Product details
Overview
SPC564A70L7CFBR from STMicroelectronics is a 32-bit Power Architecture® e200z4-based automotive MCU designed for powertrain control, featuring a 150 MHz core, 2 MB on-chip flash with ECC and read-while-write, 128 KB SRAM with ECC and standby mode, and integrated FlexCAN, FlexRay, eTPU2, and eQADC subsystems. It targets engine control units (ECUs), transmission control modules, and hybrid vehicle power management systems.
For engineers reviewing the SPC564A70L7CFBR datasheet, SPC564A70L7CFBR pinout, SPC564A70L7CFBR application, or SPC564A70L7CFBR equivalent, key selection considerations include its dual-channel FlexRay v2.1 support (10 Mbit/s), 64-message-buffer FlexCAN triple interface, 32-channel eTPU2 with reaction module, 40-channel 12-bit eQADC (688 ns min conversion), and LQFP176/PBGA324 package options for ECU layout flexibility.
Technical Context
The SPC564A70L7CFBR implements a superscalar e200z4 core with Variable Length Encoding (VLE), enabling up to two integer or floating-point instructions per cycle and four MAC operations per cycle. Its memory subsystem includes a 4-way configurable 8 KB instruction cache, 24-entry MMU, and 14 + 3 KB dedicated eTPU code/data RAM.
Peripherals are interconnected via a 4 × 4 crossbar switch (XBAR) supporting concurrent access to flash, SRAM, and peripherals. Safety-critical operation is reinforced by a 16-entry MPU, CRC unit with three submodules, junction temperature sensor, and Class 3+ Nexus debug support for core and Class 1 for eTPU.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive powertrain control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MPC5643L | 120 MHz e200z4 core; 1.5 MB flash; no FlexRay; single eQADC (32 ch) | Lacks FlexRay v2.1 and second eQADC; lower ASIL scalability | Preferred for cost-sensitive ICE-only ECUs without FlexRay networking needs |
| Renesas RH850/F1K | 32-bit RXv2 core; 2 MB flash; 192 KB RAM; 2x CAN FD; no FlexRay or eTPU | Different architecture; CAN FD instead of FlexRay; no hardware timer co-processor | Suitable where CAN FD suffices and software-defined timing replaces eTPU2 offload |
Compared with MPC5643L and RH850/F1K, the SPC564A70L7CFBR uniquely combines FlexRay v2.1, dual eQADC, and eTPU2 in a single die-enabling deterministic sub-microsecond control loops essential for high-pressure common rail and hybrid torque arbitration, where alternatives require external timing ASICs or compromise on network bandwidth.

FAQ
What is the maximum junction temperature rating for SPC564A70L7CFBR?
The SPC564A70L7CFBR has a maximum junction temperature of +150 °C, validated per JEDEC JESD51-2 and supported by on-die junction temperature sensor with ±3 °C accuracy across –40 °C to +150 °C. Thermal derating begins at 125 °C ambient under full load in LQFP176 package with 4-layer PCB and 1-in² copper pour.
Does SPC564A70L7CFBR support bootloading over CAN FD?
No. The on-chip CAN/SCI Bootstrap Loader supports only classical CAN 2.0B (up to 1 Mbit/s) and SCI UART interfaces. CAN FD is not implemented in the BAM hardware; firmware updates over higher-speed networks require external host processor or bootloader extension via FlexRay or DSPI.
How many message buffers does each FlexCAN module support?
Each of the three integrated FlexCAN modules supports exactly 64 message buffers, configurable as transmit, receive, or FIFO buffers. Buffer allocation is managed by the Message Buffer Descriptor (MBD) table in SRAM, with individual buffer sizes ranging from 8 to 64 bytes depending on ID filtering and payload requirements.
Is the eTPU2 in SPC564A70L7CFBR backward compatible with first-generation eTPU code?
No. The eTPU2 is a redesigned second-generation unit with enhanced instruction set, larger local RAM (14 KB vs. 8 KB), and added reaction module functionality. Legacy eTPU1 code requires recompilation and functional validation; register maps and microcode syntax differ significantly, and no hardware emulation mode is provided.
