Product details
Overview
SPC564L54L3CCFQR 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 for chassis and safety-critical systems. It operates up to 120 MHz, supports FlexRay (10 Mbit/s), dual FlexCAN 2.0B, and 2×12-bit ADCs with CTU synchronization - deployed in electric power steering (EPS) and brake-by-wire control units.
For engineers reviewing the SPC564L54L3CCFQR datasheet, SPC564L54L3CCFQR pinout, SPC564L54L3CCFQR application, or SPC564L54L3CCFQR equivalent, key selection criteria include LockStep vs. Decoupled core mode configuration, FCCU/RCCU fault-handling integration, FlexRay channel count and message buffer depth, and LFBGA257 thermal performance under 150 °C junction conditions.
Technical Context
The device implements a dual-core e200z4d CPU with Variable Length Encoding (VLE), MMU, 4 KB instruction cache with EDC, and Signal Processing Engine (SPE). Core operation supports both LockStep mode for ASIL-D compliance and Decoupled Parallel mode for high-throughput deterministic tasks.
Safety architecture includes Sphere of Replication (SoR) covering CPU, eDMA, and crossbar switch; Fault Collection and Control Unit (FCCU); Redundancy Control and Checker Unit (RCCU); boot-time MBIST/LBIST; and replicated junction temperature sensors. Clocking uses FMPLL with main oscillator and 16 MHz RC reference.

FAQ
What is the maximum ambient temperature rating for SPC564L54L3CCFQR?
The device is rated for ambient temperatures from –40 °C to +125 °C, with a junction temperature limit of +150 °C. This specification is validated per JEDEC JESD51-2 and applies to LFBGA257 packaging under defined PCB copper area and airflow conditions per ST's AN4217 thermal guidelines.
Does SPC564L54L3CCFQR support CAN FD?
No. The device integrates two FlexCAN 2.0B interfaces only, supporting up to 1 Mbit/s classical CAN. CAN FD capability is not implemented in the SPC564L54x series; it is available in later-generation SPC58x and SPC57x families.
How is the LockStep mode configured and verified?
LockStep is enabled via MC_ME.ME.PCTL[1].B.CORE0 = 1 and verified by FCCU.FCCU_STAT[0].CORE_LOCKSTEP = 1 after reset. Output comparison occurs at the RCCU level, and mismatch triggers immediate NMI with fault address capture in FCCU.FCCU_FES[0].
Is the on-chip flash memory capable of EEPROM emulation?
Yes. The 1 MB flash supports Read-While-Write (RWW) operation with dedicated EEPROM emulation drivers in ST's SPC56ELxx/SPC564Lxx Standard Peripherals Library. It enables wear-leveling across 16 KB sectors and achieves >100 k write/erase cycles with built-in ECC correction.
