Product details
Overview
SPC564L70L3CBFSR from STMicroelectronics is a 32-bit Power Architecture® automotive microcontroller with dual e200z4d CPU cores operating up to 120 MHz, 2 MB flash with ECC, 192 KB SRAM with ECC, and SIL3/ASIL-D safety certification for chassis and safety-critical systems. It integrates FlexCAN 2.0B, FlexRay v2.1, LINFlexD, DSPI, eTimer, FlexPWM, dual 12-bit ADCs, and Nexus Class 3+ debug.
For engineers reviewing the SPC564L70L3CBFSR datasheet, SPC564L70L3CBFSR pinout, SPC564L70L3CBFSR application, or SPC564L70L3CBFSR equivalent, key selection criteria include ASIL-D lock-step safety architecture, dual-core decoupled parallel mode, RWW EEPROM emulation, replicated FCCU/RCCU/temperature sensor/watchdog, and automotive-grade junction temperature range (–40 °C to 150 °C).
Technical Context
The device implements a Sphere of Replication (SoR) covering CPU cores, eDMA, and crossbar switch, with hardware-triggered MBIST/LBIST at boot and software-triggered ADC/flash BIST. Fault Collection and Control Unit (FCCU) receives error signals from Redundancy Control and Checker Unit (RCCU) on SoR outputs, enabling fail-safe state transitions and NMI assertion.
Its memory subsystem includes 2 MB flash with single-bit error correction and double-bit error detection (ECC), 192 KB on-chip SRAM with ECC, and RWW capability for seamless EEPROM emulation. Clock integrity is enforced via dual CMUs monitoring main oscillator, FMPLL, and RC sources, while power management uses a dedicated PMU supporting multiple low-power modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC56EL70L3CBFSR | LQFP100, 1.5 MB flash, 128 KB SRAM - smaller footprint and memory vs. SPC564L70L3 | Targeted at space-constrained modules where full LQFP144 pin count is unnecessary | Select when board area is limited and 1.5 MB flash suffices for application code + safety monitor partitioning |
| MC9S12XEQ512MAL | 16-bit HCS12X core, no FlexRay, no dual-core lock-step, ASIL-B only - legacy architecture with lower safety assurance | Suitable for cost-sensitive, non-ASIL-D chassis modules (e.g., basic power seat control) | Choose only for brownfield designs requiring pin-for-pin upgrade path; not recommended for new ASIL-D designs |
Compared with SPC56EL70L3CBFSR, the SPC564L70L3CBFSR offers higher memory capacity and LQFP144 pin count for expanded peripheral routing, while MC9S12XEQ512MAL lacks modern safety mechanisms and performance - making the SPC564L70L3CBFSR the optimal choice for new ASIL-D chassis controllers requiring FlexRay and dual-core redundancy.

FAQ
What is the maximum ambient temperature rating for SPC564L70L3CBFSR?
The device is rated for ambient temperatures from –40 °C to 125 °C, verified per AEC-Q100 Grade 1 qualification. This specification ensures reliable operation in engine bay and transmission control module environments where thermal stress is extreme and sustained.
Does SPC564L70L3CBFSR support over-the-air (OTA) firmware updates?
Yes - its 2 MB flash with RWW (Read-While-Write) capability enables concurrent execution and programming. The built-in flash controller supports atomic sector erase/write and ECC scrubbing, allowing safe OTA updates without halting safety-critical control tasks.
How does the FCCU interact with the RCCU in fault handling?
The RCCU monitors outputs of the Sphere of Replication (SoR) and flags mismatches to the FCCU, which then triggers NMI, initiates fail-safe state transitions, logs fault signatures, and can assert external error signals - forming a closed-loop hardware safety mechanism independent of software.
Can SPC564L70L3CBFSR operate without an external crystal?
Yes - it includes an internal 16 MHz RC oscillator qualified for startup and low-speed operation. However, for FlexRay, CAN FD, or precise timing-critical control loops, the external crystal (4–40 MHz) feeding the FMPLL is required to meet jitter and accuracy specifications.
