Narrative:
Back in March of 2016, Intersil released into the market place the first Class V radiation hardened CANbus transceiver family of parts.
The part was designed to be compatible with standards ISO and ESA standard.
Intersil worked closely with ESA and Airbus during the developed of this family of parts to ensure that the parts meant their functional and electrical requirements.
We worked with ESA on defining Section “Resistance to electrical CAN Network faults” in ECSS-E-ST-50-15C (May 1, 2015).
Airbus put the transceiver through an extensive component evaluation and approved the transceiver for use in June I would think that many of you are already using the these Intersil transceivers in this family. We look forward to talking with you and getting your feedback on what you like and dislike about the parts. Please come and talk to us at the Intersil booth.
The family consist of three parts. They all come in a 8Ld hermetic ceramic flatpack (CDFP) package. All three parts have the same driver and receiver circuitry. The electrical performance and specifications for the most part, are identical for the three parts.
The parts only differ in ancillary functions. The ISL72026 has a low power listen mode and loopback test capability, the ISL72027 has the low power listen mode and split termination output pin , and the ISL72028 has a low power shutdown down mode and a split termination output pin.

Three Discrete Programmable Driver Speed Selections
Resistor to Ground on the RS pin determines Speed Grade
RS = 0V (High Speed Mode – 5Mbps) Typical Driver Rise / Fall Times: 55ns / 25ns
RS = 10kΩ (Medium Speed – 250kbps) Typical Driver Rise / Fall Times: 400ns / 300ns
RS = 50kΩ (Slow Speed kbps) Typical Driver Rise / Fall Times: 700ns / 650ns
Drive RS pin HIGH
ISL72026SEH Listen Mode: TX Powered Down Supply Current: 2mA max
ISL72027SEH Listen Mode: TX Powered Down Supply Current: 2mA max
ISL72028SEH Shutdown Mode: TX and RX Powered Down Supply Current: 50µA max
Narrative:
The transceivers have three discrete driver speed selections. A single resistor from the RS pin to ground selects between the three speed options. RS = 0V selects the “High speed” option and supports data rates up to 5Mbps. The RS =10k ohms selects the medium speed option and supports data rates up to 250kbps, and RS = 50kohms selects the slow speed option and supports data rates up to 125kbps.
Driving the RS pin High will put the 26 and 27 parts into a low power listen mode and will put the 28 part into a low power shutdown mode. In listen mode the driver circuitry is powered down and the supply current of the device is reduced to 2mA to save power.
In the low power shutdown mode, both the driver and the receiver are powered down and the supply current is reduced to 50uA.

6. ISL7202xSEH (legacy): RH 3.3V CAN Bus Transceiver Family26
LBK Logic Input (Pin 5): ISL72026SEH
When a “HIGH” level is applied at the LBK pin, the device enters the loopback state.
The transceiver CANH and CANL pins are disconnected from the bus.
The driver and receiver circuitry of the transceiver remains active for diagnostic testing of the node (ECU).
VREF Output (Pin 5) for Split Termination: ISL72027SEH & ISL72028SEH
Provides a VCC / 2 output voltage for split mode termination.
Split mode termination technique is shown below. It is used to stabilize the bus voltage at VCC / 2 and prevent if from drifting to high common-mode voltage during periods of inactivity. The technique improves the electromagnetic compatibility of a network.
Split mode termination is put at each end of the bus.
CL capacitor filters unwanted high frequency noise to ground. The capacitance value used is dependent on the signaling rate of the network. A typical value used for a 1Mbps CAN network is 4.7nF, which generates a 3dB point at 1.1Mbps.
27 & 28
Narrative:
Pin 5 on the 26 part is a logic input pin labeled “LBK”. When this pin is driven high the part gets put into “loopback” mode. In loopback the CANH and CANL pins are disconnected from the bus. The driver and receiver circuitry of the transmitter remains active for diagnostic testing of the electronic control unit (ECU) connected at that node.
Pin 5 on the 27 and 28 parts is an output labeled “VREF”. It provides a VCC / 2 output voltage for applications that want to implement a split mode termination. The split mode termination is shown below. It is used to stabilize the bus voltage at VCC/2 and prevent it from drifting to high common mode voltage during periods of in activity. The technique improves the electromagnetic compatibility of a network.
Split mode termination is put a each end of the bus.
The CL capacitor filters unwanted high frequency noise to ground. The capacitance value used is dependent on the signaling rate of the network. A typical value used for a 1Mbps CAN network is 4.7nF which generates a 3dB point at 1.1Mbps.

4kV HBM
2Mbps: Receiver duty cycle: 45.5%, VOD duty cycle: 51%
5Mbps: Receiver duty cycle: 42.5%, VOD duty cycle: 49.6%
Narrative:
Our CAN transceiver was specifically designed to be compatible with the electrical specifications of ISO standard.  The ISO standard gives the loading requirements and signal levels for data rate up to 1Mbps.
Lab testing shows good signaling performance up to 5Mbps.
CAN-FD (Flexible Data Rate) is a new signaling concept where the preamble and acknowledge portions of the data packet are transmitted at 1Mbps and the data portion of the packet is transmitted at a higher data rate of 2Mbps (typical) with some pushing the data rate to 5Mbps.  Antidotal lab results shows good performance at a data rate of 2Mbps with minimal degradation in the receiver duty cycle of only 46% and VOD duty cycle at 51%. At 5Mbps the receiver duty cycle degrades to 43% and VOD duty cycle degrades slightly to 49.6%. Whether our part can meet the performance criteria of a specific CAN-FD application will be up to the customer to test and characterize their system.
Lab antidotal data shows the CAN transceiver will drive a 10ft cable with acceptable performance up to 5Mbps (Acceptable performance criteria for our testing is the differential (VOD) signal duty cycle and receiver duty cycle > 40%).  At 2Mbps the receiver duty cycle is 46% with VOD duty cycle of 50% . And at 5Mbps, the receiver duty cycle degraded to 43% and VOD duty cycle of 49.6%.  Whether our part can meet the performance criteria of a specific application will be up to the user to test and characterize their system.
They driver was designed to drive 120 nodes over a common mode range of -7V to +12V which exceeds the required ISO CM range of
-2V to +7V.
The transceiver can handle fault voltages on the BUS lines of +/-20V (both with /without beam) which exceeds the ESA ECSS-E-ST-50-15C (May 2015) fault voltage of -10V to +15V.
All pins have an ESD rating of 4kV.
The parts are Cold Spare Capable. Intersil CAN transceivers when in the powered off state does not affect the communication on the bus and present a high impedance between the bus and the system supply rail > 2MΩ (typical)
To achieve this a power down transceiver has a high resistance between the bus pins and the supply rail of > 2Mohm (typical). A powered down transceiver has a resistance between CANH and CANL of 80kohms (typical).
Intersil CAN transceivers are wafer by wafer tested to 75krad(Si)
All test are performed per MIL-STD-883, TM1019 and used a dose rate of 10mrad(Si)/s
24 devices of each type were irradiated up to 75krad(Si) followed by an anneal (168 hrs, 100°C)
All devices were bin 1 compliant after testing was complete
The parts are acceptance tested to a Low Dose Rate of 75krad(Si).
There are version B parts available that are not only LDR tested but also accepted tested to 100krad(Si) HDR.
SEL/B immune to LETTH = 86.4MeV∙cm2/mg.
Destructive SEE test summary
No SEL (single event latch-up) or SEB (single event burnout) for ions with 86MeV•cm2/mg while operating at or below the voltages of VCC = 5.5V and bus common-mode voltages of ±20V.
Single Event Transients (SET) summary
No SET detected for LET = 2.7MeV•cm2/mg (no bit errors at 1Mbps).
No missing bits but glitches on transition bits at 1Mbps and fast slew with LET = 20MeV•cm2/mg to a cross section of 4x10-7 cm2
Only single bit errors at 1Mbps and fast slew with LET = 43MeV•cm2/mg to a cross section of 4x10-6 cm2
SET was defined as any transition in the receiver output for static biasing conditions and any received bit outside of 40% to 60% duty-cycle for a 50% transmitted bit stream (250kHz and 500kHz)
SET testing results shows for a geosynchronous mission a part would experience a transmit error to heavy ion exposure no more than once every 11 years.

8. ISL7202xSEH (legacy): RH 3.3V CANbus Transceiver Family
Narrative:
The Intersil data sheets in the “Typical Performance Curves” section, has many graphs (23) that show the performance of our transceiver.
As an example:
The graph shown here, taken from the data sheet, provides a good way to see how the loading of the bus will affect the differential voltage (VOD) of the CAN signal. The graph shows how the output current of the driver changes as the VOD voltage (or loading) of the bus changes. There are three “Driver Output Current vs VOD vs Temperature” curves shown for the driver at 25degC, 85degC, and at 125degC. As you can see from the graph, the drive current goes down as the temperature is increased.
Also, superimposed on the graph are varies load lines at 20ohm, 30ohm, 60ohm, and 120ohms.
With the bus lines shorted together the part draws around 90mA (short circuit current) and with the bus floating (Not Loaded) VOD is around 3.3V.
From the graph looking where the Output current curves cross the 60ohm load line (60ohms is the standard termination load of a CAN network) the VODs can be approximated to be
2.2V at 25degC
2V at 85degC
1.9V at 125degC
ISO gives limits for differential bus voltage: 1.2Vmin to 3.0Vmax with typical value of 2.0V.
The Intersil part was designed to drive 120nodes: 120//120//666 = 55ohms. Extrapolating a 55ohm load line on the graph will show that the VOD at 55 ohms is around 1.9V to 2V. Which is well within the ISO min limit of 1.2V.

Three Parts in the Family (SMD )
All parts have the same driver and receiver circuitry
ISL72026ASEH = Listen Mode & Loopback
ISL72027ASEH = Listen Mode & Split Termination
ISL72028ASEH = Low Power Mode & Split Termination
Intersil RLR: June 2017
Product Launch: July 2017
SMD Released: August / September 2017
Intersil will be releasing the ISL7202xASEH (version A) family of the Rad Hard 3.3V CAN bus transceivers in July. The SMD should be available in September Samples, evaluation board, and Pspice models for version A parts are available.
The three parts in the family are equivalent in fit, form, function, and electrical performance to the parts in the legacy family except the medium speed selection has total loop delays and edges to support data rates up to 500kbps vs 250kbps for the legacy transceiver and slow speed has prop delays and edges to support data rates up to 250kbps vs 125kbps for the legacy parts.
Back when we developed the ISL7202xSEH legacy parts, Air Bus requested a speed grade optimized for 500kbps. The version A was developed to satisfy this customer requirement. The medium speed driver skew and rise / fall times are optimized to give good EMI performance at 500kbps and has a total loop delay to support cable lengths up to 50meters.
The slow speed driver skew and rise / fall times are optimized to give good EMI performance at 250kbps and has a total loop delay to support cable lengths up to 150meters.
The version A medium speed and slow speed circuitry was improved to give better skew performance across temperature. The version A part has tighter limits for skew than the legacy parts.
The version A family also has three parts in the family with the same ancillary functions described for the legacy parts.

Narrative:
As a reference, here is a chart that shows a comparison between the version A transceivers and the legacy transceivers signal parameter values for propagation delays, skew, rise/fall times, and total loop delays) for medium speed mode (RS= 10kohms) and slow speed mode (RS = 50kohms).
High speed is not shown because the values of the parameters between the version A parts and legacy parts are very similar.
From the chart you can see that for medium speed operation: the prop delays, skew, rise/fall times and total loop delays have been decreased for the version A parts from the legacy values to allow the version A to support 500kbps rather than 250kbps for the legacy parts.
Also from the chart you can see for slow speed that the values have decreased for the version A part from the legacy values to allow the version A to support 250kbps rather than 125kbps for the legacy parts.
Finally from the chart you can see that the 250kbps max limit for the version A parts is 400ns while the 250kbps limit for the legacy parts is 510ns. The version A has tighter limits for skew.

12. Intersil Radiation Tolerant Plastic Products Initiative Powering the Next Generation of Satellite Constellations
There is growing trend in private sector for satellite manufacturers to move away from using radiation hardened microcircuits, towards commercial off the shelf (COTs). The idea of building multiple cost effective redundant satellites verses building one satellite with redundant hardened microcircuits strives to drive the cost per satellite down in order to tolerate a single point failure in a mega-constellation.

13. Intersil Confidential Information
Introduction
Current Industry Trends and Needs
Innovation in space is being driven more by private industry giving rise to “the business of space”
Emergence of mega-constellations by the use of “small–sats” in low earth orbits
SpaceX, OneWeb, and Google the most notable examples
Reduce cost to drive reasonable profitability
Industry Solution
Migrating from traditional radiation hardened microcircuits to commercial off the shelf (COTS)
Reduce cost, increase capability by access of modern technology, decrease size (SWaP)
Industry Misconception
Limited issues will be encountered when qualifying and operating COTS devices in what is commonly thought of to be a benign low earth orbit (LEO) space environment.
Narrative:
There is a growing trend in the private sector to build many (mega-constellations) small satellites and deployed them into low earth orbits. Companies such as SpaceX, OneWeb and Google are notable companies leading this activity. In order for this mega-constellation of satellites to be profitable they are driven to reduce the cost per satellite by migrating away from traditional radiation hardened microcircuits to using commercial off the shelf (COTs) devices. Using COTs components reduce cost, gives increase capability by access of modern technology and the small footprint of COTs will decrease the satellite circuitry and overall satellite size.
We at Intersil believe an industry misconception is that minimal / limited issues will be encountered when qualifying and operating COTs devices in what they think is a relative benign environment. We feel the complexity, risk, and cost to test and qualify COTs devices is being under estimated by the manufactures of these satellites.

14. Program Profile for Next Generation Satellite Constellations
Expected Life Cycle ≤ 5 years
Satellites will be replaced with system upgrades
Total radiation exposure = krad(Si)
Margin may be needed, devices may need to meet as high as 60krad(Si)
SEE expectations = LET of 30 – 43MeV∙cm2/mg
Non-destructive SEE can be typically handled with redundancy, EDAC, filtering, etc.
Adds system level design complexity and cost
May not even be fully effective
Destructive SEE causes early termination of satellite life cycle

15. The Need for Radiation Tolerant ICs in Next Generation Constellation
Cost
Using COTS devices require up-screening before they are found suitable for space applications
The most notable tests include total ionizing dose (TID), possibly both high dose rate and low dose rate, and Single Events Effects testing.
This testing is very expensive and what seemed a less expensive alternative can end up costing more.
Risk
Radiation testing and characterization of a device today does not indicate the next lot will work
Variations in fabrication or even a change in location can affect performance with regards to radiation tolerance. These changes are often not communicated to the customer as it does not affect the electrical performance of the device.
Reliability
NASA has published reports indicating that a large percentage of “small-sats” are dead on arrival or cease operation much before the expected life. Using more reliable devices suited for the harsh environments of space will help with assuring mission success.
Narrative:
Intersil feels there is market for Radiation Tolerant ICs for these next generation constellations satellites for the following reasons:
Cost: Using COTs devices require up screening before they are found suitable for space applications. Most notably tests needed are total ionizing dose (TID) possibly both high dose rate and low dose rate, and Single Events Effects testing. This testing is very expensive and what seemed a less expensive alternative can end up being very costly.
Risk: Radiation testing and characterization of a COTs device today, does not indicate that the next lot of the COTs device will work – variations in fabrication or even change in manufacturing location can affect performance with regards to radiation tolerance. These changes are often not communicated to the customer by the commercial IC manufacturer as it does not affect the electrical performance of the device.
Reliability: NASA has published reports indicating that a large percentage of small satellites are dead on arrival or cease operation much before the expected life. Using more reliable devices suited for the harsh environment of space will help assuring mission success.
As a result Intersil is developing a family of Radiation Tolerant Plastic ICs as an alternative to using COTs devices. During development, an Intersil radiation tolerant (RL) IC goes through TID testing and SEE testing during the characterization of the IC. The results of the TID testing and SEE testing are included in the data sheet for the part.

There are two parts in the ISL70x17SEH “Instrumentation Amplifier with Integrated ADC Driver” family. The ISL70517SEH and ISL70617SEH. The 517 has a singled ended output while the 617 has a differential output. The parts come in a 24Ld ceramic flat-pack package.
The parts have a wide supply range of +/-4V to +/-18V. They have a programmable gain range of 0.1 to 10,000. They feature excellent CMRR and PSRR and ultra low offset voltage and very low input bias current.
They are radiation acceptance tested to a low dose rate of 75krad(Si). They are SEB tested to an LET of 60MeV.
The parts feature an Integrated Rail to Rail ADC driver output stage that can be powered from a different supply voltage than the input state, which allows the output of the IN Amp to be powered from the same supply of the ADC to be able to maximize the dynamic range of the ADC. They have the ability to attenuate and gain for added flexibility.
Evaluation Boards are available. Intersil data sheet, SMD, Evaluation board documentation, Pspice model, radiation reports both ELDRs and SEE, and a white paper are available at the Intersil web site.

Cold Spare Capability
Reliability is an essential requirement in space applications and single point failures must be avoided
To achieve a high reliable communication system a node will use two CAN transceivers in parallel
One transceiver will be active while the other transceiver will be a cold spare (in a powered down condition)
The cold spare transceiver gets used if the active transceiver malfunctions
Intersil CAN transceivers when in the powered off state does not affect the communication on the bus and present a high impedance between the bus and the system supply rail > 2MΩ (typical)

38. Total Ionizing Dose Performance
Intersil CAN transceivers are wafer by wafer tested to 75krad(Si)
All test are performed per MIL-STD-883, TM1019 and used a dose rate of 10mrad(Si)/s
24 devices of each type were irradiated up to 75krad(Si) followed by an anneal (168 hrs, 100°C)

39. Single Event Effects (SEE) Performance
Destructive SEE test summary
No SEL (single event latch-up) or SEB (single event burnout) for ions with 86MeV•cm2/mg while operating at or below the voltages of VCC = 5.5V and bus common-mode voltages of ±18V.
Single Event Transients (SET) summary
No SET detected for LET = 2.7MeV•cm2/mg (no bit errors at 1Mbps).
No missing bits but glitches on transition bits at 1Mbps and fast slew with LET = 20MeV•cm2/mg to a cross section of 4x10-7 cm2
Only single bit errors at 1Mbps and fast slew with LET = 43MeV•cm2/mg to a cross section of 4x10-6 cm2
SET was defined as any transition in the receiver output for static biasing conditions and any received bit outside of 40% to 60% duty-cycle for a 50% transmitted bit stream (250kHz and 500kHz)
SET testing results shows for a geosynchronous mission a part would experience a transmit error to heavy ion exposure no more than once every 11 years.
