Product details
Overview
SPC560P40L3CEFAY from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 256 KB on-chip flash memory (ECC-protected), 20 KB SRAM (ECC-protected), and 64 MHz CPU clock, designed for chassis and safety-critical systems including electronic braking and steering control. It integrates dual FlexCAN 2.0B interfaces (one configurable as a safety port up to 8 Mbit/s), LINFlex, DSPI, FlexPWM, and a 10-bit ADC with <1 µs conversion time.
For engineers reviewing the SPC560P40L3CEFAY datasheet, SPC560P40L3CEFAY pinout, SPC560P40L3CEFAY application, or SPC560P40L3CEFAY equivalent, key selection criteria include ASIL-B-ready fail-safe features (programmable watchdog, NMI, Fault Collection Unit), Nexus Class 1 debug support, LQFP100 package compatibility, and automotive-grade temperature range (–40 °C to 125 °C).
Technical Context
The SPC560P40L3CEFAY implements a single-issue e200z0h core compliant with Power Architecture® embedded category and supports Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes 256 KB main flash with ECC and erase/program controller, plus 64 KB data flash (4 × 16 KB banks) for EEPROM emulation - both with error correction and wear-leveling support.
Peripheral integration centers on functional safety: dual FlexCAN controllers (one dedicated safety port), 16-channel eDMA, programmable cross-triggering unit (CTU) linking ADC and PWM, and fail-safe modules including Software Watchdog Timer (SWT), Non-Maskable Interrupt (NMI), and Fault Collection Unit (FCU) for fault logging and system recovery coordination.
