Product details
Overview
SPC564L70L3BCOSR 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 FlexCAN 2.0B, FlexRay v2.1, LINFlexD, DSPI, eTimer, FlexPWM, dual 12-bit ADCs, and Nexus Class 3+ debug.
For engineers reviewing the SPC564L70L3BCOSR datasheet, SPC564L70L3BCOSR pinout, SPC564L70L3BCOSR application, or SPC564L70L3BCOSR equivalent, key selection criteria include ASIL-D lock-step safety architecture, dual-core decoupled parallel mode, RWW EEPROM emulation, replicated FCCU/RCCU, 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) aggregates errors from replicated paths and manages fail-safe responses including NMI assertion and safe state entry.
Its safety architecture includes redundant clock monitoring units (CMU), replicated junction temperature sensors, 16-region MPU, Cyclic Redundancy Check (CRC) unit, and dual-channel FlexRay supporting 10 Mbit/s data rates - all validated for ISO 26262 ASIL-D compliance in chassis control 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 |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-R52 dual-core, 320 MHz max, 4 MB flash, AURIX-style safety peripherals but different diagnostic coverage model | Targets next-gen zonal architectures with Ethernet AVB; less mature toolchain for legacy Power Architecture migration | Prefer when migrating to ARM-based AUTOSAR Adaptive platforms or requiring integrated Ethernet MAC |
| Renesas RH850/P1M | 32-bit RXv3 core, 200 MHz, 2 MB flash, ISO 26262 ASIL-D certified but lacks FlexRay and native RWW EEPROM emulation | Better suited for body control modules than chassis due to limited high-speed deterministic bus support | Choose where CAN/LIN dominance suffices and cost-sensitive production volumes require mature Japanese automotive supply chain |
Compared with SPC564L70L3BCOSR, the S32K344 offers higher compute throughput but requires architectural revalidation for Power Architecture-based legacy software, while the RH850/P1M delivers strong CAN/LIN integration but omits FlexRay - making SPC564L70L3BCOSR uniquely balanced for ASIL-D chassis systems needing FlexRay + lock-step + RWW in a single die.

FAQ
What is the maximum ambient temperature rating for SPC564L70L3BCOSR?
The device is rated for ambient temperatures from –40 °C to 125 °C per its LQFP100 package specification (DocID023953 Rev 5, Section 3.3). This rating applies to board-level thermal conditions meeting JEDEC JESD51-2 guidelines, with junction temperature limited to 150 °C under continuous operation.
Does SPC564L70L3BCOSR support CAN FD?
No. The device integrates three FlexCAN 2.0B controllers only, compliant with ISO 11898-1:2015 (Classical CAN). It does not implement CAN FD frame format, bit-rate switching, or enhanced payload length - confirmed in Section 1.5.26 of the datasheet and functional block diagram (Figure 1).
How is RWW (Read-While-Write) implemented in the flash memory?
RWW is enabled via dedicated flash sectors configured for concurrent read and write operations using the Platform Flash Memory Controller (PFMC). The device supports background programming of one sector while executing code from another, verified in Section 1.5.7 and electrical characteristics Table 26 (Flash program/erase specs).
Is Nexus Class 3+ debug supported in production silicon?
Yes. Nexus Class 3+ interface is fully implemented in SPC564L70L3BCOSR production silicon, including real-time trace, data watchpoints, and non-intrusive execution monitoring. This capability is documented in Section 1.5.38 (Nexus port controller) and validated in ST's SPC5 Studio IDE and Lauterbach TRACE32 toolchain support notes.
