Product details
Overview
SPC564A70B4 from STMicroelectronics is a 32-bit Power Architecture® e200z4-based automotive MCU targeting powertrain control units (PCUs), featuring 150 MHz core frequency, 2 MB on-chip flash with ECC and read-while-write, 128 KB SRAM with standby/ECC, and integrated FlexRay v2.1 (10 Mbit/s, dual-channel) for engine management systems.
For engineers reviewing the SPC564A70B4 datasheet, SPC564A70B4 pinout, SPC564A70B4 application, or SPC564A70B4 equivalent, key selection criteria include ASIL-B capable safety architecture (MPU, CRC, temperature sensor), multi-protocol serial connectivity (3×FlexCAN, 3×DSPI, 3×eSCI, FlexRay), and automotive-grade power management (5 V/3.3 V/1.2 V supply scheme).
Technical Context
The SPC564A70B4 implements a superscalar e200z4 core with Variable Length Encoding (VLE), supporting up to two integer or floating-point instructions per cycle and four MAC operations per cycle. Its memory subsystem includes 2 MB flash with ECC and RWW capability, 128 KB SRAM (32 KB in standby mode with ECC), and an 8 KB configurable instruction cache.
Peripherals are interconnected via a 4×4 crossbar switch (XBAR) and managed by a 24-entry MMU. Safety features include a 16-entry MPU, triple-CRC unit, junction temperature sensor, and Class 3+ Nexus debug support for core and Class 1 for eTPU2 - all aligned with ISO 26262 requirements for powertrain ECUs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive powertrain microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MPC5643L | Same e200z4 core, 128 MB flash, no FlexRay; uses Qorivva platform with different peripheral set (no eTPU2) | Lacks FlexRay and reaction module; suited for mid-tier powertrain but not ASIL-D FlexRay domains | Select when FlexRay is unnecessary and legacy Qorivva toolchain compatibility is required. |
| Renesas RH850/P1M | 32-bit RXv2 core (not Power Architecture), 2 MB flash, 256 KB SRAM, supports CAN FD and Ethernet AVB but no FlexRay | Stronger functional safety certification (ASIL-D ready), broader automotive software ecosystem, but no native FlexRay PHY | Prefer for new designs requiring ASIL-D compliance and future-proofing beyond FlexRay-dependent architectures. |
Compared with the SPC564A70B4, the MPC5643L offers comparable compute but lacks FlexRay and eTPU2 for advanced timing-critical functions, while the RH850/P1M delivers higher safety certification and modern networking but requires external FlexRay transceivers and re-architected timing firmware.

FAQ
What is the maximum operating junction temperature for the SPC564A70B4?
The SPC564A70B4 is rated for a maximum junction temperature of +150 °C, validated per AEC-Q100 Grade 1 qualification. Thermal characteristics are specified in Doc ID 18078 Rev 4, Table 12, with θJA = 22.5 °C/W for PBGA324 under JEDEC JESD51-2 conditions. This rating enables deployment in engine bay locations near exhaust manifolds or turbochargers.
Does the SPC564A70B4 support bootloading over CAN without external hardware?
Yes - the device integrates an on-chip CAN/SCI Bootstrap Loader with Boot Assist Module (BAM), allowing firmware updates via CAN messages without external programming hardware. The BAM validates checksums and supports secure flash programming through protected memory regions defined by the MPU.
How many independent CAN message buffers does each FlexCAN module support?
Each of the three FlexCAN modules supports exactly 64 message buffers, configurable as transmit, receive, or FIFO buffers. Buffer allocation is managed via the Message RAM (MRAM) with hardware-assisted filtering and prioritization - enabling concurrent handling of engine, transmission, and chassis CAN traffic without CPU intervention.
Is the eTPU2 in the SPC564A70B4 backward-compatible with first-generation eTPU code?
No - the eTPU2 is a second-generation implementation with enhanced instruction set, larger local RAM (14 + 3 KB vs. 8 KB), and added reaction module functionality. While timing-critical channel logic can be ported, assembly-level eTPU code requires modification due to architectural changes in event processing and resource mapping.
