Product details
Overview
SPC564L54L5CBFSY from STMicroelectronics is a 32-bit Power Architecture® automotive microcontroller featuring dual e200z4d cores, 1 MB Flash with ECC, 128 KB SRAM with ECC, and SIL3/ASILD-certified safety architecture including LockStep mode, FCCU, RCCU, and boot-time MBIST/LBIST. It integrates FlexCAN 2.0B, FlexRay v2.1, LINFlexD, DSPI, eTimer, FlexPWM, dual 12-bit ADCs, and Nexus Class 3+ debug - deployed in chassis control units and electronic braking systems.
For engineers reviewing the SPC564L54L5CBFSY datasheet, SPC564L54L5CBFSY pinout, SPC564L54L5CBFSY application, or SPC564L54L5CBFSY equivalent, key selection criteria include ASIL-D safety certification, dual-core LockStep vs. Decoupled Parallel operation modes, FlexRay channel count (2) and message buffer depth (64), flash ECC coverage, and LFBGA257 thermal performance at 150 °C junction temperature.
Technical Context
The SPC564L54L5CBFSY implements a replicated sphere-of-replication (SoR) covering CPU cores, eDMA, and crossbar switch, with redundant outputs verified by RCCU and aggregated into FCCU for fault classification and safe state management. Its dual e200z4d cores support both LockStep (for functional safety) and Decoupled Parallel (for performance) execution modes, managed via MC_ME module configuration.
Memory subsystem includes 1 MB on-chip Flash with single-bit error correction/detection and 128 KB SRAM with ECC, both supporting RWW for EEPROM emulation. Safety-critical peripherals - including dual 12-bit ADCs with CTU synchronization, FlexCAN with 32 message objects, and FlexRay with 10 Mbit/s data rate - are integrated within the SoR or monitored via dedicated CRC/FCCU paths.

FAQ
What safety certifications does the SPC564L54L5CBFSY hold?
The SPC564L54L5CBFSY is certified to ISO 26262 ASIL-D at the device level and IEC 61508 SIL3, validated through integrated safety mechanisms including LockStep core replication, FCCU fault classification, RCCU output checking, boot-time MBIST/LBIST, and replicated temperature sensing - all documented in ST's safety manual UM1823.
Does this MCU support concurrent FlexRay and FlexCAN operation?
Yes - the SPC564L54L5CBFSY simultaneously operates its FlexRay v2.1 module (2 channels, 64 message buffers) and two FlexCAN 2.0B interfaces (32 message objects each) without resource conflict, enabled by the crossbar switch and independent DMA channels; timing coherency is maintained via shared system clock and Nexus-triggered synchronization.
What is the maximum achievable ADC sampling rate with CTU synchronization?
With CTU triggering, the dual 12-bit ADCs achieve synchronized sampling at up to 1.2 MSps per channel (2.4 MSps aggregate), limited by conversion time (≤833 ns) and CTU propagation delay; full 16-channel scan completes in ≤13.3 µs, enabling real-time motor current reconstruction in EPS applications.
Is external RAM required for typical ASIL-D chassis applications?
No - the integrated 128 KB SRAM with ECC is sufficient for ASIL-D runtime data, stack, safety monitor variables, and communication buffers; ST's reference designs (e.g., SPC56EL-KIT) demonstrate full ESC/EPS firmware operation using only on-chip memory, eliminating external RAM BOM cost and failure modes.
