NEXT SLIDE COMPANY PROFILE

3. Vinculum Vinculum (pl. vincula) stands for a bond or tie.
VNC1 is a dual USB Host/Slave interface with an 8 bit CPU and 32 bit coprocessor. .
Lots of very happy customers designing into a multitude of applications from coffee machines, commercial ovens to CNC.
BUT – “can we have the capability to write our own firmware”
“can we have more flexibility in hardware”
“can we have smaller and larger packages with more resources”
Wanted to be able to programme themselves with own code
Comes with various “flavours” of FTDI’s tested and proven embedded firmware which is programmed into the internal, easily upgradeable, Flash memory
Price expectation for some applications too low – change technology and geometry.
NEXT SLIDE PRODUCT INTRODUCTION

4. Product Introduction VNC2
Vinculum-II (VNC2) is FTDI’s 2nd generation of dual USB Host/Slave ICs.
Programmable SoC device with a powerful general purpose embedded 16 bit CPU core – it just so happens it also has USB host/slave capability !!
Hardware designed to handle all USB data transfers, freeing up external processing power for the user application plus the ability to run in low power modes.
Flexible hardware system solution with a programmable selection of available interfaces on all 6 package options.
Integrated ‘C’ based software design environment (compiler, assembler, linker, debugger, RTOS, drivers) provides an “easy to use” firmware design solution.
-2nd generation. Building on FTDIs USB experience and what the customer wants.
Custom designed CPU with increased processing capability over the VNC1L – allowing for a system cost reduction based on the fact that any existing system using an external PIC to run the VNC1L can be removed from the system.
Building on FTDIs competitive advantage of fully supporting designers and customers by delivering a complete solution, VNC2 enhances the initial member of the Vinculum family, the VNC1L, by reducing the device cost as well as introducing the capability for designers to develop their own application firmware and programme the host controller themselves.
Flexibility of hardware/system design and lower power solutions as well as the added flexibility offered by the software IDE.
With VINC2, FTDI are not moving into the uchip space. FTDI are a silicon company operating in the niche USB market space, and we provide a complete solution to our customers.
FTDI have listened to their customers requests – they know what we can deliver and they know what they would like to see
FTDI have developed VNC2 as an answer to these requests – delivering the USB solution – USB made easy./
NEXT SLIDE HARDWARE ACHITECTURE

5. HW Architecture NEXT SLIDE HARDWARE FEATURES
And here is a block diagram of the hardware.
Without trying to go into too much depth, the heart of the IC is the embedded 16bit custom built CPU – custom built means efficient. – which uses the embedded flash and RAM which is the memory within the brain.
Briefly mention the interfaces which will be discussed in the next 2 slides
Briefly mention the IO interfacing and how it provides system flexibility.
Briefly mention possible applications.
NEXT SLIDE HARDWARE FEATURES

6. HW Features
Dual full-speed/low-speed USB 2.0 interfaces which can be independently configured as either USB host or slave.
Custom designed, 16 bit SoC CPU powerful enough that no external CPU required to handle USB engine .
Increased Flash and RAM memory provide large user areas of memory for customised applications.
Flexible peripheral interface selection (next slide).
Powerful debugger interface.
Reduced power modes available, including suspend current of <200uA.
Flexible product package offering – 6 different packages.
The 48 pin LQFP package is backward compatible with Vinculum-I device.
So what’s under the hood?
FTDI have developed a custom CPU and increased the memory capability over the VNC1L. Why a new CPU ?– efficiency of silicon area and performance.
The hardware has been designed to answer designers “flexible hardware” requirements with the flexible peripheral interface – which we will look at on next slide.
The hardware also adds an extremely powerful debug capability which allows designers to explore what is happening in the silicon through a single pin.
FTDI have also recognised the requirement for reduced power modes – hence the 3 different power operating capabilities
But they have added even more choice for the designer offering a range of packages from 32pin to 64 pin – including a backward compatible 48 pin offering – resolving PCB area verses functional requirements of some application.

Also mention support for Bulk, Interrupt, Isochronous and Control USB transfers.
NEXT SLIDE PERIPHERAL INTERFACES

7. Peripheral Interfaces
Other than the dual USB Host/Slave capability, VNC2 has the following resources which are available in all package sizes:
Universal Asynchronous Receiver Transmitter (UART)
2 Serial Peripheral Interface (SPI) Slaves
SPI Master
Debugger Interface
Parallel FIFO Interface (245 mode)
General Purpose Timers
8 Pulse Width Modulation blocks (PWM)
General Purpose Input Output (GPIO)
Selection of ‘resources  IO’ is made via the I/O Multiplexer .
The VNC2 has a number of peripheral interfaces – as listed here.
The beauty of VNC2 is that a designer has the option to chose which of these peripherals he needs to use.
Every package size has all the peripherals. The designer can pick-n-mix whish ones he needs.
He also has the flexibility of routing these peripheral to a number of different pins – a very flexible solution.
SO how do we use all these magnificent features.
There is a choice of 3 package sizes.
Internally all 3 packages have access to all these peripheral.... But the limitation of their use is the number of pins on the package. Each of these peripherals requires to use a number of package pins – for example the UART needs at least 4 pins. Each package has a number of available pins which these peripherals can be routed to.The user decides what he wants and he programs the peripherals to connect to external pins. This is achieved using the I/O mux.
There is an obvious limitation that the smaller packages.
Lets look at the overall software architecture of the how the VNC2 talks to a user application and what tools FTDI provide to “make USB easy”

Lets take a brief look at the actual tools available to the deisgner
A designer has an application.
The application wants to talk to the device –how?
VNC1L has a monolithic firmware model which does not make provision for users to develop their own application code.
With VNC2 the firmware model has evolved to provide flexibility, code maintainability, performance, stability and ease of use.
The firmware application has a layered architecture consisting of:
User application.
Device Manager (FTDI-supplied) – provides user application access to the IC. Layered on top of the Kernel services
Kernel Services (FTDI-supplied) – provides RTOS, interrupt servicing and application profiling.
In complete the solution, FTDI have also provided the hardware drivers and the upper level USB specific drivers which talk to the hardware.
Last but not least is the tool-chain – a set of tools which gets us back to the user and helps him with his application – llets take a closer look at the toolchain.
