Product details
Overview
SPC564L54L3CCFQY 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 operates from −40 °C to 125 °C ambient and supports FlexRay (10 Mbit/s), dual FlexCAN 2.0B, and LINFlexD for chassis control systems.
For engineers reviewing the SPC564L54L3CCFQY datasheet, SPC564L54L3CCFQY pinout, SPC564L54L3CCFQY application, or SPC564L54L3CCFQY equivalent, key selection criteria include ASIL-D safety certification, dual-core LockStep execution, on-chip RWW EEPROM emulation, FlexRay V2.1 Rev. A compliance, and LFBGA257 package thermal performance at 150 °C junction temperature.
Technical Context
The SPC564L54L3CCFQY implements a dual-issue, five-stage pipeline e200z4d CPU core running up to 120 MHz with Variable Length Encoding (VLE) and Signal Processing Engine (SPE). Its memory subsystem includes 1 MB flash with ECC and 128 KB SRAM with ECC, both supporting RWW operation for real-time firmware updates.
Safety-critical operation is enabled by Sphere of Replication (SoR) covering CPU cores, eDMA, and crossbar switch; Fault Collection and Control Unit (FCCU); Redundancy Control and Checker Unit (RCCU); and hardware-triggered MBIST/LBIST. It integrates FlexRay v2.1 Rev. A (2 channels, 64 message buffers), two FlexCAN 2.0B interfaces (32 message objects each), and dual 12-bit ADCs with CTU synchronization.

The SPC564L54L3CCFQY is rated for a maximum junction temperature of 150 °C, validated per JEDEC JESD51 standards and supported by thermal characterization data in Section 3.5 of the datasheet. This rating enables reliable operation in under-hood environments such as EPS motor housings and brake control modules where ambient temperatures exceed 125 °C.
Does SPC564L54L3CCFQY support boot-time self-test for flash memory?
Yes - the device supports software-triggered boot-time Built-In Self-Test (BIST) for flash memory, as documented in Section 1.5.41 and Table 30 of the datasheet. This test verifies flash integrity before application code execution and is part of the ISO 26262 ASIL-D safety mechanism suite.
Can SPC564L54L3CCFQY operate in Decoupled Parallel mode?
Yes - the dual e200z4d cores support Decoupled Parallel mode, allowing independent instruction streams for high-performance non-safety tasks while retaining LockStep mode for safety-critical routines. This mode is configured via MC_ME module registers and detailed in Section 1.5.1 of the datasheet.
Which package variants are offered for SPC564L54L3CCFQY?
The SPC564L54L3CCFQY is exclusively available in the LFBGA257 package (14 mm × 14 mm, 0.8 mm pitch) with exposed thermal pad, as specified in Section 4.2 and Table 44 of the datasheet.
