Challenges and Solutions

System Challenges

PXS30 Solutions

Reduce System

Costs and Simplify

Design

• Reduces design complexity and component count by putting key functional

safety features on a single chip

• Dual processing spheres, including CPU, DMA, interrupt controller, crossbar and

MPU for logic level fault detection

• Dual z7 CPU architecture provides performance to address real-time applications and

cross-checking functions common in many safety strategies, which reduces hardware

and software complexity used in multiple MCU designs. The architecture can be run in

two statistically configurable modes of operation.

• Lockstep operation provides a software environment for redundant processing

and calculations

• Independent core operation (dual parallel mode) provides a software environment

for diverse processing and calculations to increase performance or to cross

check for reliable operation

• Built-in flexible hardware self-test capabilities provide diagnostic coverage both

at logic and memory level

• Fault collection and control unit manages MCU behavior in the event internal

MCU logic faults and signals these to external system components

• FlexRay™ protocol and safety ports for robust communications

• Probability of undetected failure per hour (PFH) = 0.1 FIT (one failure per every

10 billion hours)

• Designed to target safety requirements outlined in IEC61511 and IEC61508

(SIL3), which reduces system cost and effort

Precise Control

for Real-Time

Applications

• e200 z7 CPU at 180 MHz provides computational performance targeted at

vector-oriented control of motor applications

• Dual-core architecture provides computation ability for complex applications or

cross-checking requirements of safety applications

• Precise control of integrated electric motor control periphery

• Advanced PWM for specialized multi-phase motor control requirements

• Configurable alignment

• High frequency above 100 MHz

• Dead time insertion

• Skew correction

• Cross-triggering unit coordinates ADC, timer and PWM generation and

minimizes CPU interrupt load eTimer units handle rotor position and speed

acquisition and offer six dual-action IC/OC channels with incremental/quadrature

encoder mode

• Two 12-bit ADCs offer precise conversion for an improved driving experience

• FlexRay protocol for fault-tolerant communications with other networked

modules within the vehicle

• Up to 2 MB flash

• Up to 512 KB SRAM

• Motor control library of common functions

• Ability to control two three-phase motors

The PXS30 dual-core architecture can be

statically switched from lockstep mode

to decoupled parallel mode (independent

core operation) for applications needing

maximum performance or software diversity.

A wide variety of industrial applications can

be supported, such as motion and power

control. For example, the new cross-triggering

unit allows control of up to two brushless DC

motors or multiple actuators with a minimum

interrupt load. Additional features include

Ethernet, a fault collection unit, multiple

communication modules, two 12-bit ADCs,

eTimer units and a built-in hardware self test.

SafeAssure Program:

Functional Safety. Simplified.

Freescale’s SafeAssure functional safety

program is designed to help system

manufacturers more easily achieve system

compliance with functional safety standards:

International Standards Organization (ISO)

26262 and IEC 61508. The program

highlights Freescale solutions—hardware

and software—that are optimally designed to

support functional safety implementations and

come with a rich set of enablement collateral.
