Product details
Overview
SPC56AP54L5CEFAY 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, one FlexRay v2.1 module (dual/single channel, 64 message buffers), and a safety port derived from FlexCAN-enabling fail-safe communication in brake control, airbag deployment, and electronic stability control.
For engineers reviewing the SPC56AP54L5CEFAY datasheet, SPC56AP54L5CEFAY pinout, SPC56AP54L5CEFAY application, or SPC56AP54L5CEFAY equivalent, key selection criteria include its dual-core fault collection unit (FCCU), Nexus® L2+ debug interface, 10-bit ADC with 27 channels and <1 µs conversion time, and support for –40 to 125 °C ambient operation in LQFP144 packaging.
Technical Context
This MCU implements a single-issue e200z0h core running at 64 MHz with Variable Length Encoding (VLE) and integrated safety architecture including ECC on Flash/SRAM, SWT with pseudo-random servicing sequence, and dedicated Fault Collection and Control Unit (FCCU). Its crossbar switch (XBAR) enables concurrent peripheral access without arbitration bottlenecks.
The device features two independent INTC controllers, a 16-channel eDMA with multiple request sources, and hardware-level safety mechanisms: Safety Port (FlexCAN-derived), register protection scheme, and Safe Mode SoC entry. Clocking includes FMPLL, main oscillator, and 16 MHz RC oscillator with defined electrical specs per operating voltage (3.3 V or 5 V).
