SPC570Sx Getting Started
Introduction
®
The SPC570Sx devices family is built on Power Architecture
technology and is targeted for
ABS and airbag applications that require a high safety integrity level (ISO 26262 for ASIL-D
safety integrity).
In order to minimize additional software and module level features to reach this target, an
on-chip redundancy is offered for the critical components (see Functional Safety chapter of
RM) of the microcontroller by an e200z0Hn2p core, a DMA controller and an interrupt
controller in a delayed lockstep configuration, a crossbar bus system, a memory protection
unit, a fault collection and control unit (FCCU), Flash and SRAM with end-to-end error
correction coding (ECC) and End to end (E2E) protection on the data path and memory
ECC.
This family operates up to 80MHz and offers a high performance processing power specially
if compared with the previous family (SPC56) within a similar power envelope.
Some hardware in the new family also helps to prevent and control critical electronics
system faults and protects against harmful hacks.
This application note details the steps required to properly initialize the SPC570Sx devices
family from power-up to the code execution.
A development flow is described throughout the application note to explain the steps.
It is intended that this application note is read along with the SPC570Sx reference manual,
that can be obtained from the STMicroelectronics website at

(see
Section D.1: Reference
documents).
