Product details
Overview
SPC560P54L5BEAAY from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 1088 KB Flash (1024 KB code + 64 KB EEPROM emulation), 80 KB ECC-protected SRAM, and AEC-Q100 qualification for chassis/safety systems. It integrates dual FlexCAN 2.0B interfaces, FlexRay v2.1, 2 LINFlex, 5 DSPI, 2 eTimer units, 10-bit ADC with 27 channels, and fail-safe features including FCCU, safety port, and Nexus® L2+ debug.
For engineers reviewing the SPC560P54L5BEAAY datasheet, SPC560P54L5BEAAY pinout, SPC560P54L5BEAAY application, or SPC560P54L5BEAAY equivalent, this device supports deterministic real-time control in brake-by-wire, electronic stability control, airbag controllers, and chassis domain ECUs requiring ASIL-B compliance, functional safety monitoring, and multi-protocol vehicle networking.
Technical Context
The SPC560P54L5BEAAY implements a single-issue e200z0h CPU core running at 64 MHz with Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes ECC-protected Flash and SRAM, coupled with a crossbar switch (XBAR) enabling concurrent access to peripherals and memory by CPU and eDMA.
Fail-safe operation is enforced via dedicated hardware: Fault Collection and Control Unit (FCCU) monitors internal errors, Safety Port provides redundant CAN communication, and Software Watchdog Timer (SWT) uses pseudo-random servicing sequences. The system supports dual-voltage I/O (3.3 V or 5 V) and operates across −40 °C to 125 °C ambient temperature.

FAQ
What is the maximum junction temperature specification for SPC560P54L5BEAAY?
The SPC560P54L5BEAAY is rated for operation up to 150 °C junction temperature, validated per AEC-Q100 stress test conditions. Thermal characteristics for the LQFP144 package are specified in DocID18340 Rev 6 Table 12, with θJA = 26.5 °C/W under standard JEDEC PCB conditions.
Does SPC560P54L5BEAAY support JTAG and Nexus® simultaneously?
No-JTAG and Nexus® share physical pins (TCK/TMS/TDI/TDO/TRST) and are mutually exclusive modes. Nexus® L2+ is enabled via configuration of the NEXUS_EN bit in the SIUL_MSCR register; JTAG requires disabling Nexus and asserting TRST to enter boundary-scan mode.
How is EEPROM emulation implemented in the 64 KB data flash section?
ST's proprietary EEPROM emulation uses wear-leveling and atomic page-write algorithms across the 64 KB data flash region. It provides byte-addressable read/write access, 100k write cycles endurance, and automatic background garbage collection managed by the Flash Program/Erase Controller (FPEC).
Can the safety port operate concurrently with CAN0 and CAN1 interfaces?
Yes-the safety port is implemented as a third FlexCAN instance (CAN2) with independent message buffers and registers. It shares the same physical CAN transceiver pins only when configured in "safety port" mode; otherwise, it functions as a standard FlexCAN interface alongside CAN0/CAN1.
