Product details
Overview
SPC564A70L7COCR from STMicroelectronics is a 32-bit Power Architecture® e200z4-based automotive MCU targeting powertrain control units, 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), 3× FlexCAN (64 msg buffers each), and dual eQADCs (40 channels, 12-bit, 688 ns min conversion). It supports LQFP176 packaging and operates under AEC-Q100 Grade 1 conditions.
For engineers reviewing the SPC564A70L7COCR datasheet, SPC564A70L7COCR pinout, SPC564A70L7COCR application, or SPC564A70L7COCR equivalent, key selection considerations include its dual eTPU2 + reaction module for real-time engine timing, FMPLL clock synthesis with 4–40 MHz oscillator support, fail-safe features (MPU, CRC, junction temp sensor), and multi-rail power architecture (5 V / 3.3 V / 1.2 V).
Technical Context
The SPC564A70L7COCR 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 24-entry MMU, 8 KB instruction cache (configurable 2-/4-way), and 14+3 KB dedicated eTPU RAM.
Real-time peripheral coordination is handled by a 4×4 crossbar switch (XBAR), supporting concurrent access to flash, SRAM, and peripherals. The fail-safe architecture integrates a 16-entry MPU, triple-CRC submodules, and a junction temperature sensor - all validated for ASIL-B compliant powertrain software stacks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive powertrain microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5643L | Same e200z4 core, but 1.5 MB flash, no FlexRay, single eQADC (32 ch), LQFP176 only | Lacks FlexRay and second eQADC - unsuitable for x-by-wire or high-channel-count combustion analysis | Select when FlexRay and dual ADC are not required; lower cost for legacy powertrain designs |
| SPC574S50E1 | ARM Cortex-M4F core, 2 MB flash, 384 KB SRAM, no eTPU2, FlexRay v2.1, dual eQADC | Different architecture (ARM vs Power Architecture); lacks hardware time-processing unit for ultra-low-latency event handling | Prefer for new AUTOSAR Classic projects requiring ARM ecosystem tools; avoid where eTPU2-level timing determinism is mandatory |
Compared with MPC5643L, SPC564A70L7COCR adds FlexRay and dual eQADC for next-gen architectures; versus SPC574S50E1, it retains eTPU2 for sub-microsecond engine event response - critical for gasoline direct injection timing accuracy.

FAQ
What is the maximum junction temperature rating for SPC564A70L7COCR?
The SPC564A70L7COCR is qualified for AEC-Q100 Grade 1 operation, with a maximum junction temperature of +125 °C. Thermal characteristics are specified across LQFP176, LBGA208, and PBGA324 packages, and the integrated junction temperature sensor provides real-time monitoring with ±3 °C accuracy over the full operating range.
Does SPC564A70L7COCR support JTAG boundary scan and Nexus debugging simultaneously?
Yes - the device implements a 5-pin JTAG interface compliant with IEEE 1149.1 and Nexus Class 3+ debug architecture. Both interfaces share the same physical TDI/TDO/TMS/TCK pins but operate in mutually exclusive modes; Nexus provides real-time trace and complex breakpoint capabilities, while JTAG supports boundary scan testing and flash programming.
How many CAN 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 via the Message Buffer Descriptor Table (MBDT) in SRAM, with hardware arbitration and priority encoding ensuring deterministic latency for safety-critical messages like throttle position or brake status.
Is the SPC564A70L7COCR pin-compatible with other members of the SPC564A70 family?
No - SPC564A70L7COCR uses the LQFP176 package, while SPC564A70B4 is offered in LBGA208 and PBGA324 variants. Pinouts differ significantly across packages due to distinct ball/pin assignments, power rail distribution, and peripheral multiplexing. Migration requires PCB redesign and signal routing validation per package-specific datasheet figures (Fig. 2–4).
