Product details
Overview
SPC584C80E3G0C0X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller with dual e200z420n3 cores running at up to 180 MHz, 4 MB on-chip flash (4096 KB code + 128 KB data), Hardware Security Module (HSM), and ASIL-B compliance per ISO 26262 for safety-critical powertrain and chassis control applications.
For engineers reviewing the SPC584C80E3G0C0X datasheet, SPC584C80E3G0C0X pinout, SPC584C80E3G0C0X application, or SPC584C80E3G0C0X equivalent, this MCU delivers deterministic real-time performance with dual-core lock-step support, integrated Ethernet AVB/TSN, CAN-FD, FlexRay, and comprehensive safety mechanisms including FCCU, MEMU, and end-to-end ECC across memory and crossbar paths.
Technical Context
The SPC584C80E3G0C0X implements a dual-core e200z420n3 architecture with Variable Length Encoding (VLE) and single-precision floating-point units, each with 64 KB local data RAM, 8 KB I-Cache, and 4 KB D-Cache. It uses a crossbar switch (XBAR) with end-to-end ECC to enable concurrent access to Flash, SRAM, and peripherals by multiple bus masters.
Safety is enforced via a dedicated Fault Collection and Control Unit (FCCU), Memory Error Management Unit (MEMU), and dual PLLs-one for stable peripheral clocking and one for FM-modulated computational domains-alongside hardware CRC units and delayed lock-step redundancy checkers for core-level fault detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-M7 dual-core, 320 MHz, 4 MB flash, ASIL-D capable; lacks integrated Ethernet MAC and FlexRay. | Better suited for ASIL-D safety islands but requires external PHY and FlexRay transceiver; higher power consumption in active mode. | Select when ASIL-D decomposition is required and Ethernet/FlexRay are implemented externally. |
| Renesas RH850/U2A | 32-bit RXv3 core, 240 MHz, 4 MB flash, ASIL-B certified; no HSM, limited CAN-FD channels (4), no Ethernet. | Optimized for legacy automotive body control; lacks hardware-accelerated crypto and time-sensitive networking features. | Select for cost-sensitive body ECU designs where Ethernet and secure OTA are not required. |
Compared with S32K344 and RH850/U2A, the SPC584C80E3G0C0X uniquely integrates Ethernet AVB, FlexRay, and a certified HSM in a single ASIL-B package-reducing BOM count and PCB area while enabling secure, time-deterministic domain controller architectures without external co-processors.

FAQ
What is the maximum junction temperature rating for SPC584C80E3G0C0X?
The SPC584C80E3G0C0X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 stress testing. This enables deployment in under-hood environments such as engine control units and transmission control modules without derating.
Does SPC584C80E3G0C0X support AUTOSAR OS and MCAL drivers?
Yes, ST provides certified AUTOSAR 4.3+ MCAL drivers and OS integration packages for SPC584C80E3G0C0X, including support for dual-core scheduling, memory protection unit (MPU) configuration, and safety monitor services aligned with ISO 26262 Part 6.
How is the Hardware Security Module (HSM) isolated from the main CPU subsystem?
The HSM is physically isolated with dedicated 1.2 V power rails (HSM_VDD/HSM_VSS), separate clock domains, and private bus interface to its 176 KB flash and 32 KB data RAM. Access is strictly controlled via TrustZone-like gatekeepers and authenticated mailbox protocols-no direct CPU read/write access permitted.
Can SPC584C80E3G0C0X operate in stop mode with Ethernet and CAN-FD active?
No-Ethernet MAC and MCAN modules require active clock domains and cannot retain full functionality in STOP mode. However, the device supports Smart Standby mode with LIN/CAN wake capability and RTC operation at <10 µA, allowing selective peripheral retention while maintaining network presence.
