Product details
Overview
SPC584C70E3GMC1X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller with dual e200z420n3 cores running at 180 MHz, 4 MB on-chip flash (4096 KB code + 128 KB data), Hardware Security Module (HSM), and ASIL-B functional safety compliance per ISO 26262 - deployed in engine control units for real-time combustion timing, sensor fusion, and secure firmware updates.
For engineers reviewing the SPC584C70E3GMC1X datasheet, SPC584C70E3GMC1X pinout, SPC584C70E3GMC1X application, or SPC584C70E3GMC1X equivalent, this page delivers verified core architecture, safety subsystem details, CAN-FD/Ethernet timing specs, and validated pin mapping for ECU hardware integration and AUTOSAR stack porting.
Technical Context
The device implements a dual-core lock-step-capable e200z420n3 CPU complex with Variable Length Encoding (VLE), 8 KB I-Cache and 4 KB D-Cache per core, and 64 KB local data RAM per core. It integrates a crossbar switch with end-to-end ECC for concurrent access to Flash, SRAM, and peripherals by multiple bus masters.
Safety is enforced via FCCU for failure notification handling, MEMU for memory error reporting, CRC units for data integrity, and a dedicated HSM with 176 KB flash (144 KB code + 32 KB data) supporting cryptographic acceleration. Clocking uses dual PLLs: one for stable peripheral domains and another for FM-modulated computational shell operation.

FAQ
What is the maximum junction temperature rating for SPC584C70E3GMC1X?
The device is rated for a junction temperature range of –40 °C to +150 °C and qualified per AEC-Q100 Grade 1. This specification is validated across process corners and lifetime stress testing, enabling deployment in under-hood environments such as engine compartments and transmission control housings without derating.
Does SPC584C70E3GMC1X support CAN FD with simultaneous classical CAN operation?
Yes - it integrates eight independent MCAN modules, each compliant with ISO 11898-1:2015 (CAN FD). Each module supports concurrent classical CAN and CAN FD frames via flexible bit-rate switching, and all share a unified message RAM architecture with configurable TX/RX buffers for mixed-protocol networks.
How is the Hardware Security Module (HSM) isolated from the main application cores?
The HSM is implemented as a physically separate subsystem with its own 176 KB flash (144 KB code + 32 KB data), dedicated e200z0 core, and isolated bus interface. Access to HSM resources is strictly controlled via firewall registers in the System Integration Unit Lite (SIUL2), preventing unauthorized read/write operations from main cores or DMA channels.
Can SPC584C70E3GMC1X operate in ultra-low-power standby mode with RTC wake-up?
Yes - it supports Smart Standby mode with RTC active, consuming less than 10 µA typical. Wake-up sources include LIN bus activity, CAN message reception, GPIO interrupts, and periodic RTC alarms. The RTC maintains timekeeping accuracy ±5 ppm over –40 °C to 105 °C using the internal 32 kHz crystal oscillator.
