Product details
Overview
SPC58EC80E7QMC1X 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), 384 KB general-purpose SRAM, and integrated Hardware Security Module (HSM) supporting ASIL-B compliance per ISO 26262. It targets engine control units (ECUs), transmission control modules, and advanced driver assistance systems (ADAS) domain controllers requiring high-integrity real-time processing.
For engineers reviewing the SPC58EC80E7QMC1X datasheet, SPC58EC80E7QMC1X pinout, SPC58EC80E7QMC1X application, or SPC58EC80E7QMC1X equivalent, key selection criteria include dual-core lock-step safety architecture, ISO CAN-FD support across 8 MCAN interfaces, IEEE 802.3-2008 10/100 Mbps Ethernet with IEEE 1588 timestamping, and HSM-based cryptographic acceleration for secure boot and OTA updates.
Technical Context
The SPC58EC80E7QMC1X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers and dedicated Memory Error Management Unit (MEMU) to detect and report memory errors in flash, SRAM, and peripheral registers. Its crossbar switch (XBAR) enables concurrent bus master access to peripherals, Flash, and RAM with end-to-end ECC protection across all data paths.
It integrates two independent phase-locked loops: PLL0 provides stable clock domains for peripherals and communication interfaces, while PLL1 supplies the FM modulation domain for computational shell timing. The device supports AUTOSAR-compliant real-time operation via 8 PIT channels, RTC/API, and 568-source interrupt controller (INTC) with configurable priority levels.

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, 2 MB flash, no integrated Ethernet MAC; uses external PHY for 100BASE-T1. | Lacks native IEEE 1588 timestamping and AVB support; requires additional silicon for time-sensitive networking. | Preferred when ARM toolchain compatibility and lower cost outweigh need for integrated Ethernet features. |
| Renesas RH850/U2A | 32-bit RXv3 core, 4 MB flash, 512 KB SRAM; supports ASIL-D but lacks HSM with crypto accelerators. | Requires external secure element for OTA key management; higher power consumption in active mode (120 MHz max). | Selected where highest ASIL level (D) is mandatory and cryptographic offload is handled externally. |
Compared with NXP S32K344 and Renesas RH850/U2A, the SPC58EC80E7QMC1X uniquely combines ASIL-B certification, integrated 10/100 Ethernet with AVB/IEEE 1588, and on-die HSM crypto acceleration-enabling single-chip domain controller designs without external PHYs or secure elements.

FAQ
What is the maximum junction temperature rating for SPC58EC80E7QMC1X?
The SPC58EC80E7QMC1X is rated for continuous operation at junction temperatures from –40 °C to +150 °C, validated per AEC-Q100 Grade 0 stress testing. This enables deployment in under-hood environments such as engine compartments and power inverters without derating.
Does SPC58EC80E7QMC1X support AUTOSAR OS and MCAL drivers?
Yes, STMicroelectronics provides certified AUTOSAR 4.3+ MCAL drivers and OS support for the SPC58EC80E7QMC1X through its SPC5 Studio development ecosystem. These drivers cover all on-chip peripherals including MCAN, DSPI, eMIOS, and Ethernet, and are qualified for ASIL-B applications.
How is the Hardware Security Module (HSM) accessed and configured?
The HSM is accessed exclusively via dedicated mailbox registers over the internal AXI bus; it runs proprietary firmware stored in its 176 KB dedicated flash. Configuration is performed during boot via Boot Assist Flash (BAF) using serial CAN or LIN/UART, with keys provisioned through JTAG-secured debug interfaces.
Can SPC58EC80E7QMC1X operate in a lock-step configuration with external watchdog supervision?
No-lock-step operation is internal and hardware-enforced between the two e200z420n3 cores with built-in redundancy checkers and FCCU reporting. External watchdog supervision is unnecessary for ASIL-B compliance; the integrated Software Watchdog Timer (SWT) and Fault Collection and Control Unit (FCCU) provide complete failure detection and reaction.
