Product details
Overview
SPC560P34L1CEFAY from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 192 KB on-chip Flash (ECC-protected), 20 KB SRAM (ECC-protected), and 64 MHz CPU clock, designed for chassis and safety-critical systems including airbag controllers and brake control units.
For engineers reviewing the SPC560P34L1CEFAY datasheet, SPC560P34L1CEFAY pinout, SPC560P34L1CEFAY application, or SPC560P34L1CEFAY equivalent, key selection criteria include FlexCAN 2.0B compliance with 32 message buffers, LINFlex dual-channel support (1× Master/Slave + 1× Master-only), and integrated safety features including Fault Collection Unit (FCU) and programmable watchdog timer.
Technical Context
The SPC560P34L1CEFAY 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 192 KB main flash with ECC and erase/program controller, plus 64 KB data flash (4 × 16 KB banks) for EEPROM emulation.
It integrates fail-safe peripherals including a non-maskable interrupt (NMI), Nexus Class 1 debug interface, and a Safety Port based on FlexCAN capable of 8 Mbit/s at 64 MHz - usable as a second CAN interface when not configured for safety-critical messaging.
