Product details
Overview
SPC564A70L7COBY from STMicroelectronics is a 32-bit Power Architecture® automotive MCU featuring a 150 MHz e200z4 core, 2 MB on-chip flash with ECC and read-while-write, 128 KB SRAM with standby/ECC, and integrated FlexRay (V2.1), triple FlexCAN (64 buffers each), and dual eQADCs (40 channels, 688 ns min conversion). It targets engine control units (ECUs) requiring ASIL-B functional safety compliance and real-time deterministic timing.
For engineers reviewing the SPC564A70L7COBY datasheet, SPC564A70L7COBY pinout, SPC564A70L7COBY application, or SPC564A70L7COBY equivalent, key selection criteria include FMPLL-based clock generation, eTPU2 with 32 standard channels + reaction module, Nexus Class 3+ debug support, and PBGA324/LQFP176 package options for high-pin-count powertrain domain controllers.
Technical Context
The SPC564A70L7COBY 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.
Real-time peripheral integration centers on three FlexCAN modules (each with 64 message buffers and hardware filtering), one FlexRay controller (dual/single channel, 128 message objects, ECC), and dual eQADCs supporting simultaneous sampling across 40 12-bit inputs. The eTPU2 unit provides deterministic timing for spark/fuel injection with 32 standard channels plus a 6-channel reaction module delivering three outputs per channel.

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, only dual FlexCAN, 64 KB SRAM | Lacks FlexRay and half the SRAM; suitable for cost-sensitive non-FlexRay ECUs like throttle controllers | Select when FlexRay is unnecessary and BOM cost reduction outweighs diagnostic bandwidth needs. |
| Renesas RH850/F1L | 32-bit RXv2 core, 1.5 MB flash, 192 KB RAM, CAN FD only (no FlexRay), 12-bit ADC (1 μs min) | Higher ADC latency and no FlexRay limit use in high-integrity powertrain domains requiring time-triggered comms | Prefer for CAN FD–centric architectures where ISO 26262 ASIL-D decomposition is achieved via software partitioning instead of hardware redundancy. |
Compared with MPC5643L and RH850/F1L, the SPC564A70L7COBY uniquely combines FlexRay V2.1, triple FlexCAN, and eTPU2 with 2 MB flash-making it the only option among the three qualified for next-generation x-by-wire engine control where deterministic FlexRay backbone synchronization is mandatory.

FAQ
What is the maximum operating junction temperature for SPC564A70L7COBY?
The SPC564A70L7COBY is rated for a maximum junction temperature of +150 °C, validated per AEC-Q100 Grade 0 qualification. This rating enables deployment in under-hood locations near turbochargers or exhaust manifolds where ambient temperatures exceed 125 °C, provided PCB thermal design meets ST's recommended copper pour and via guidelines in AN4485.
Does SPC564A70L7COBY support CAN FD?
No, the SPC564A70L7COBY integrates three FlexCAN modules compliant with ISO 11898-1 (Classical CAN only), each supporting up to 1 Mbps and 64 message buffers. It does not implement CAN FD physical layer or protocol enhancements; CAN FD capability requires migration to ST's SPC58NG or SPC58NE families.
How is functional safety (ASIL) achieved in this MCU?
ASIL-B compliance is achieved through hardware-level safety mechanisms: 16-entry MPU for memory access enforcement, dual ECC on flash/SRAM, CRC unit with three independent submodules for data path verification, and lockstep-capable Nexus debug interface for runtime diagnostics. These features are documented in ST's SPC564A70 Safety Manual (UM1807).
What development tools are officially supported for SPC564A70L7COBY?
ST officially supports SPC564A70L7COBY with the SPC5 Studio IDE (v5.x), SPC5-UDESTK evaluation board, and Lauterbach TRACE32 debugger with Nexus Class 3+ probe support. Production programming uses ST's SPCTool with CAN/SCI bootloader or dedicated JTAG programmers such as Segger J-Link PRO with SPC5-specific firmware.
