Product details
Overview
SPC564A70L7CFAY 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 SPC564A70L7CFAY datasheet, SPC564A70L7CFAY pinout, SPC564A70L7CFAY application, or SPC564A70L7CFAY equivalent, key selection considerations include its triple FlexCAN (64-message buffers each), dual eQADC (40×12-bit channels, 688 ns min conversion), eTPU2 with 32 standard + 6 reaction channels, and support for LQFP176/PBGA324 packages in AEC-Q100 Grade 1 environments.
Technical Context
The SPC564A70L7CFAY 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 2 MB flash with ECC and RWW capability, 128 KB SRAM (32 KB with standby mode), and an 8 KB configurable instruction cache.
Peripheral integration centers on deterministic real-time I/O: three FlexCAN modules (64 message buffers each), one FlexRay v2.1 controller (128 message objects, ECC), two eQADCs (40 input channels, 688 ns conversion), and second-generation eTPU2 with dedicated reaction module (6 channels × 3 outputs). Clocking uses an on-chip FMPLL with 4–40 MHz crystal input.

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 older DSPI instead of downstream MSC-enhanced DSPI. | Lacks FlexRay v2.1 and dual eQADC; suitable for legacy CAN-only powertrain designs without high-speed deterministic bus requirements. | Select when FlexRay integration is unnecessary and cost-sensitive CAN-based architectures dominate. |
| Renesas RH850/F1L | 32-bit RXv2 core (not Power Architecture), 1.5 MB flash, 192 KB RAM, supports CAN FD but no FlexRay; different toolchain and safety certification path. | Targets ASIL-B/D applications with strong compiler/tooling ecosystem; lacks eTPU2-level deterministic I/O for spark timing. | Prefer for new designs prioritizing long-term toolchain continuity and CAN FD over FlexRay, especially outside strict Power Architecture migration paths. |
Compared with MPC5643L and RH850/F1L, the SPC564A70L7CFAY uniquely delivers FlexRay v2.1 + triple FlexCAN + eTPU2 in a single die-enabling consolidated high-speed deterministic networking and ultra-low-latency I/O critical for next-gen ICE/hybrid powertrain ECUs.

FAQ
What is the maximum junction temperature rating for SPC564A70L7CFAY?
The SPC564A70L7CFAY is rated for maximum junction temperature of +150 °C and operates across ambient temperatures from −40 °C to +125 °C (AEC-Q100 Grade 1). Thermal characteristics are validated per JEDEC JESD51 standards, with θJA = 22.5 °C/W for LQFP176 and 14.2 °C/W for PBGA324 packages under defined PCB layout conditions.
Does SPC564A70L7CFAY support hardware-based functional safety features for ISO 26262 compliance?
Yes. The device integrates hardware safety mechanisms including ECC on flash and SRAM, 16-entry MPU for memory isolation, CRC unit with three independent submodules, error correction status module (ECSM), and Nexus Class 3+ debug for runtime verification-supporting ASIL-B system-level compliance per ISO 26262 Part 5 Annex D.
Can SPC564A70L7CFAY execute code from RAM while writing to flash?
Yes. The 2 MB on-chip flash supports true read-while-write (RWW) operation, allowing execution from one flash block while programming or erasing another. This capability is essential for safe in-field firmware updates and bootloader implementations without halting real-time control tasks.
What package variants are offered for SPC564A70L7CFAY, and are they pin-compatible?
The SPC564A70L7CFAY is offered in LQFP176 and PBGA324 packages. These are not pin-compatible: LQFP176 uses perimeter leads with 0.5 mm pitch; PBGA324 uses area-array balls with 1.0 mm pitch and distinct signal mapping per Figures 2 and 4–7 in Doc ID 18078 Rev 4. Designers must select package-specific reference layouts and routing rules.
