Product details
Overview
SPC564L70L3CBFSY from STMicroelectronics is a 32-bit Power Architecture® automotive microcontroller with dual e200z4d 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 FlexRay (2 channels, 10 Mbit/s), three FlexCAN 2.0B interfaces, and dual 12-bit ADCs with cross-triggering-deployed in electronic brake control units (EBCU) and steer-by-wire ECUs.
For engineers reviewing the SPC564L70L3CBFSY datasheet, SPC564L70L3CBFSY pinout, SPC564L70L3CBFSY application, or SPC564L70L3CBFSY equivalent, key selection criteria include lock-step core redundancy, FCCU fault reporting latency, RWW EEPROM emulation capability, and Nexus Class 3+ debug support for ISO 26262 ASIL-D development workflows.
Technical Context
The device implements a Sphere of Replication (SoR) architecture covering CPU cores, eDMA controllers, and crossbar switch-monitored by a dedicated Fault Collection and Control Unit (FCCU) that aggregates errors from replicated outputs via RCCU. Boot-time hardware-triggered MBIST/LBIST and software-triggered ADC/flash BIST provide deterministic safety coverage.
It supports Decoupled Parallel mode for non-safety high-performance tasks while maintaining lock-step operation for safety partitions; clock monitoring units (CMU) supervise both main oscillator and FMPLL outputs, and the 16-region MPU enforces memory isolation between safety and non-safety software partitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC56EL70L3CBKAY | LQFP144 package (20 × 20 mm), same core/peripherals but higher pin count for expanded I/O and additional CAN/FlexRay routing flexibility. | Better suited for multi-sensor chassis controllers requiring >80 GPIOs and separate power domains for analog/digital sections. | Select when board layout requires larger I/O fanout or thermal dissipation margin beyond LQFP100 limits. |
| TC297TP128F200NAC | TriCore™ architecture (Infineon), 200 MHz, 4 MB flash, ASIL-D certified-but lacks native FlexRay PHY and uses different safety library ecosystem. | Preferred in German OEM platforms with existing AURIX™ toolchain investment and CAN FD + Ethernet focus over FlexRay. | Choose only if migrating from legacy TriCore designs or when Ethernet AVB integration is mandatory. |
Compared with SPC564L70L3CBFSY, the SPC56EL70L3CBKAY offers identical safety architecture in a larger package for complex I/O routing, while the TC297TP128F200NAC trades FlexRay integration for higher clock speed and Ethernet readiness-requiring revalidation of safety drivers and debug toolchains.

FAQ
What is the maximum junction temperature rating for SPC564L70L3CBFSY?
The device is qualified for a junction temperature range of −40 °C to 150 °C, validated per JEDEC JESD22-A108 and reflected in thermal resistance values (θJA = 32.5 °C/W for LQFP100). This enables deployment in under-hood environments near powertrain components without forced cooling.
Does SPC564L70L3CBFSY support RWW (Read-While-Write) for EEPROM emulation?
Yes-it features built-in RWW capability in its 2 MB flash memory with ECC, allowing concurrent code execution from one flash bank while programming another. This enables seamless firmware updates and robust data logging without interrupting safety-critical tasks.
How does the Fault Collection and Control Unit (FCCU) interface with the Redundancy Control and Checker Unit (RCCU)?
The RCCU continuously compares outputs from replicated modules (e.g., CPU ALU results, eDMA descriptors) and sends mismatch flags directly to the FCCU. The FCCU then logs the fault type, location, and timestamp, and can assert NMI or initiate a controlled shutdown-meeting ASIL-D fault reaction time requirements (<10 ms).
Can the SPC564L70L3CBFSY operate with a single 3.3 V supply?
Yes-the device operates from a single 3.0 V to 3.6 V supply, internally generating all required voltage domains (core, analog, I/O) via integrated regulators. No external LDOs are needed for basic operation, though separate VDDA/VDD decoupling per datasheet Table 10 is mandatory for ADC accuracy and EMC compliance.
