Product details
Overview
SPC564A70L7COCY from STMicroelectronics is a 32-bit Power Architecture® automotive MCU designed for powertrain control, featuring a 150 MHz e200z4 core with VLE and superscalar execution, 2 MB on-chip flash with ECC and RWW, 128 KB SRAM with standby/ECC, and integrated FlexCAN, FlexRay, eTPU2, and dual eQADCs. It targets engine control units (ECUs) requiring high-integrity real-time processing under ASIL-B conditions.
For engineers reviewing the SPC564A70L7COCY datasheet, SPC564A70L7COCY pinout, SPC564A70L7COCY application, or SPC564A70L7COCY equivalent, key selection considerations include its dual eQADC (40-channel, 12-bit, 688 ns min conversion), 3 FlexCAN modules (64 message buffers each), FlexRay v2.1 support (10 Mbit/s, 128 message objects), and fail-safe features including CRC unit, MPU, and junction temperature sensor.
Technical Context
The SPC564A70L7COCY implements a dual-issue 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 read-while-write capability and ECC, plus 128 KB SRAM segmented into 32 KB standby-capable banks with ECC protection.
Peripherals are interconnected via a 4×4 crossbar switch (XBAR) supporting concurrent access to flash, SRAM, and peripherals. Safety-critical functions are reinforced by a 16-entry MPU, three independent CRC submodules, and a dedicated junction temperature sensor - all aligned with ISO 26262 ASIL-B requirements for powertrain applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | e200z4 Power Architecture® @ 150 MHz; superscalar dual-issue with VLE for code density and deterministic timing. |
| Flash Memory | 2 MB on-chip with ECC and read-while-write (RWW); enables safe in-field firmware updates without halting execution. |
| SRAM | 128 KB total: 32 KB with standby retention + full ECC; supports low-power sleep modes while preserving critical state. |
| eQADC | Dual enhanced queued ADCs: 40 total 12-bit input channels, 688 ns minimum conversion time; suitable for fast engine sensor sampling. |
| FlexCAN | 3 modules, each with 64 message buffers; supports CAN FD-ready protocols and time-triggered communication for ECU synchronization. |
| FlexRay | Single FlexRay v2.1 controller: 10 Mbit/s, dual/single channel, 128 message objects with ECC; meets automotive x-by-wire timing determinism. |
| eTPU2 | Second-generation enhanced Time Processing Unit: 32 standard channels + 6-output reaction module; offloads precise timing-critical tasks (e.g., ignition, injection) from main core. |
Pinout & Package
SPC564A70L7COCY is packaged in LQFP176 (24 mm × 24 mm), with 176 pins arranged in quad flat pack format optimized for automotive PCB layout and thermal management. Pin functions are defined across five voltage domains (VDD, VDDIO, VDDA, VSS, VSSA) and include dedicated safety monitoring pins (e.g., TSENS, NMI, RESET).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDIO, VDDA | Power supply inputs | Separate 5 V (core/IO), 3.3 V (analog), and 1.2 V (internal regulator) rails enable noise isolation and domain-specific power gating. |
| RESET, NMI | System reset and non-maskable interrupt | Hardware-initiated recovery path for fault containment; NMI supports safety-critical event capture independent of INTC. |
| TSENS | Junction temperature sensor output | Analog voltage output proportional to die temperature; used for thermal derating and ASIL-B-compliant thermal monitoring. |
| MSCx_CLK, MSCx_DATA | Micro Second Channel clock/data | High-precision timing interface for synchronized actuator control across multiple ECUs (e.g., cylinder balancing). |
| FRAY_TX, FRAY_RX | FlexRay differential transceiver I/O | Integrated termination and slew-rate control compliant with FlexRay physical layer spec v2.1 for deterministic bus arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-Safe Protection | 16-entry MPU, triple CRC submodules, and dedicated temperature sensor enable hardware-enforced memory partitioning and runtime integrity checks per ISO 26262. |
| Real-Time Peripheral Offload | eTPU2 + reaction module handles 32+ timing-critical I/O events (e.g., spark timing, fuel pulse width) with <100 ns jitter - freeing CPU for higher-layer control logic. |
| Dual eQADC with Queue Engine | Two independent 12-bit ADCs with hardware-managed conversion queues and trigger synchronization reduce software overhead and improve sampling consistency across engine cycles. |
| Nexus Class 3+ Debug | Full-core debug visibility including instruction trace, data watchpoints, and real-time register access - essential for ASIL-B validation and certification evidence generation. |
| Flexible Clock Generation | On-chip 4–40 MHz crystal oscillator + FMPLL supports dynamic frequency scaling and clock domain isolation between safety and non-safety partitions. |
Applications

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, but 1.5 MB flash, single eQADC (32 ch), no FlexRay; uses different pinout and package (PBGA256). | Lacks FlexRay and second eQADC; suitable for cost-sensitive gasoline ECUs without x-by-wire requirements. | Select when FlexRay and dual high-speed ADCs are not required, and legacy MPC56xx toolchain compatibility is prioritized. |
| Renesas RH850/F1K | 32-bit RXv2 core @ 120 MHz, 2 MB flash, dual 12-bit eADC (32 ch), CAN FD only - no FlexRay or eTPU2. | Strong CAN FD and functional safety support (ASIL-D capable), but no hardware time-processing unit for ultra-low-jitter actuation. | Prefer for CAN FD-centric architectures needing higher ASIL coverage, where eTPU2-level timing precision is not mandatory. |
Compared with MPC5643L and RH850/F1K, the SPC564A70L7COCY uniquely combines FlexRay v2.1, dual eQADC, and eTPU2 in a single ASIL-B-certifiable package - making it optimal for next-gen gasoline/diesel ECUs requiring multi-protocol networking and sub-microsecond actuator control.

FAQ
What is the maximum operating junction temperature for SPC564A70L7COCY?
The SPC564A70L7COCY has a maximum rated junction temperature of +150 °C, validated per JEDEC JESD51-1 and specified in Section 3.3 of the preliminary datasheet (Doc ID 18078 Rev 4). Thermal derating begins above +125 °C ambient under full load, and the integrated junction temperature sensor provides real-time monitoring with ±3 °C accuracy across the full range.
Does SPC564A70L7COCY support bootloading over CAN or SCI?
Yes - the device integrates an on-chip CAN/SCI Bootstrap Loader with Boot Assist Module (BAM), enabling firmware updates via CAN frames or serial commands without external programming hardware. The BAM supports secure entry into bootloader mode using configurable pin states and checksum verification before code execution.
How many independent clock domains does the SPC564A70L7COCY support?
The SPC564A70L7COCY supports four independent clock domains: core (e200z4), peripheral (XBAR-connected modules), ADC (eQADC), and debug (Nexus/JTAG). Each domain is driven by configurable dividers from the FMPLL or internal oscillator, allowing dynamic power/performance trade-offs and ASIL-B domain isolation.
Is the LQFP176 package RoHS-compliant and qualified for automotive reflow profiles?
Yes - the SPC564A70L7COCY in LQFP176 uses ST's ECOPACK®2 lead-free packaging and is qualified for automotive-grade reflow per J-STD-020D (peak temperature 260 °C, 60-second duration). Moisture sensitivity level is MSL3, and the package meets AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) reliability requirements.
