Product details
Overview
SPC564L54L5CBFSR from STMicroelectronics is a 32-bit Power Architecture® automotive MCU 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 at up to 120 MHz and supports FlexRay (10 Mbit/s), dual FlexCAN 2.0B, and LINFlexD for chassis control systems.
For engineers reviewing the SPC564L54L5CBFSR datasheet, SPC564L54L5CBFSR pinout, SPC564L54L5CBFSR application, or SPC564L54L5CBFSR equivalent, key selection criteria include ASIL-D functional safety compliance, dual-core LockStep vs. Decoupled Parallel mode operation, FlexRay V2.1 Rev. A timing validation, and LFBGA257 thermal performance at 150 °C junction temperature.
Technical Context
The SPC564L54L5CBFSR implements a replicated Sphere of Replication (SoR) covering CPU cores, eDMA, and crossbar switch, with hardware-triggered MBIST/LBIST and software-triggered ADC/Flash BIST. Its Fault Collection and Control Unit (FCCU) aggregates errors from SoR outputs via Redundancy Control and Checker Unit (RCCU).
It integrates dual 12-bit ADCs with programmable Cross Triggering Unit (CTU) for synchronized sampling with eTimer and FlexPWM, plus a Sine Wave Generator (SWG) with integrated low-pass filter for analog actuator control in real-time chassis applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC564L60L5CBFSR | 1.5 MB Flash, 256 KB SRAM, same safety architecture and peripheral set | Higher memory capacity required for complex chassis middleware stacks or OTA update partitions | Select when >1 MB code+data footprint or dual-bank RWW for seamless firmware updates is mandatory |
| TC297TP128F200NAC | TriCore™ architecture, 200 MHz, AURIX™ safety concept (HSM + CCU), no FlexRay | Requires migration from Power Architecture toolchain; lacks native FlexRay but adds HSM for secure boot | Choose for new designs prioritizing AUTOSAR-compliant TriCore ecosystem and hardware security over FlexRay legacy integration |
Compared with SPC564L54L5CBFSR, the SPC564L60L5CBFSR offers scalable memory for evolving chassis software, while the TC297TP128F200NAC shifts to TriCore with stronger security features but abandons FlexRay-making it suitable only where FlexRay is deprecated and HSM is required.

FAQ
What safety certifications does the SPC564L54L5CBFSR hold?
The SPC564L54L5CBFSR is certified to SIL3 per IEC 61508 and ASIL-D per ISO 26262, validated through its LockStep architecture, FCCU/RCCU safety monitors, boot-time MBIST/LBIST, and production-tested failure modes. Certification evidence is documented in ST's safety manual UM1823 and FMEDA reports.
Does this MCU support FlexRay communication out of the box?
Yes - the SPC564L54L5CBFSR integrates a fully compliant FlexRay v2.1 Rev. A module with two independent channels, 64 message buffers, and configurable data rates up to 10 Mbit/s. Hardware initialization, frame transmission, and error handling are supported by the FRAY driver library in SPC5 Studio.
What is the purpose of the Sine Wave Generator (SWG) peripheral?
The SWG generates precise analog sine waves via digital-to-analog conversion followed by an on-chip low-pass filter. It is used for biasing analog sensors (e.g., resolver excitation), driving voice coil actuators in active suspension, or providing reference signals in closed-loop chassis control systems.
Can the dual e200z4d cores operate independently, or only in LockStep?
Both modes are supported: LockStep for ASIL-D critical tasks (e.g., torque calculation), and Decoupled Parallel mode for non-safety background processing (e.g., diagnostics, CAN message routing). Mode selection is controlled via MC_ME register configuration at boot or runtime.
