2 Owner : JOCA Cypress Confidential Sales Training 3/15/2013 CYPRESS INTERNAL USE ONLY TI UCD90160 Overview TI UCD90160 is a 64-pin, 16-rail power supply sequencer and monitor featuring : 12-bit ADC with 0.5% internal Vref and sampling rate of 400 µs for all rails Closed loop margining for 10 rails 4 programmable OV/UV thresholds per monitor Non volatile Flash based fault entries (x12) JTAG and I2C/SMBus/PMBus interfaces TI UCD90160 finds application in : Industrial equipment Telecommunication and networking equipment Servers and storage systems Any system requiring sequencing and monitoring of multiple power rails TI UCD90160 is a fast power sequencer and monitor backed by TI’s expertise in power management solution TI UCD90160

3 Owner : JOCA Cypress Confidential Sales Training 3/15/2013 CYPRESS INTERNAL USE ONLY Challenges Using TI UCD Increased # of power rails increases costs and decreases system reliability Newer designs have 20+ power rails that require 2+ TI UCD90160s for sequencing and voltage monitoring Additional functions like current monitoring, temperature sensing etc. require more TI UCD90160s and/or other ICs Higher # of ICs increases the # of PoFs which reduces the system reliability 2. Power rails demand better accuracy than 1% Accurate voltage and current monitoring is critical to system reliability Latest FPGAs and DSPs have low-voltage rails (<1 V ) requiring sub-0.5% monitoring accuracy TI UCD90160 has a low internal VRef accuracy which leads to a low ADC monitoring accuracy (>1%) 3. Each board requires complex customization Each design has different number of power rails needing different functionality on each rail TI UCD90160 has an inflexible I/O system that limits customization PSoC 3 solves these problems Supports up to 32 power rails per chip, 2x that of TI UCD90160, and integrates more functions on the same chip; Reduces BOM cost and # of PoFs Monitors voltage and current with 0.26% accuracy Creates customized power rail configurations PSoC 3 provides a One-chip, Customized, Reliable Power Supervision Solution Each server would require 2-4 TI UCD90160s Rack Mounted Servers

5 Owner : JOCA Cypress Confidential Sales Training 3/15/2013 CYPRESS INTERNAL USE ONLY Customer Objections to Adopting PSoC 3 over TI UCD90160 “The design only needs support for < 16 rails” PSoC 3 solution is customizable and can be used to support just the required # of rails Flexible I/O system allows the remaining pins to be used to integrate functions like temperature sensing, fan control, I2C mux etc. “TI UCD90160 is a cheaper solution” PSoC 3 solution can integrate other functions that would have required separate ICs PSoC 3 has been able to reduce BOM costs by 50% in certain design wins “Previous design was using TI UCD90160” / “More familiar with TI UCD90160” PSoC 3 offers better features and performance than the TI UCD90160 Easy-to-use ‘ Drag and Drop’ implementation on PSoC Creator and supporting training modules allow for easy migration

6 Owner : JOCA Cypress Confidential Sales Training 3/15/2013 CYPRESS INTERNAL USE ONLY Sales Cautions for PSoC 3 32x and 34x PSoC devices have a lower ADC accuracy These devices have a 1% reference voltage accuracy (as opposed to a 0.1% accuracy for 36x and 38x devices) This leads to a lower ADC accuracy rating between 0.6% to 1% which is still comparable to other devices in the market
