Product details
Overview
SPC58EC80E7QMC0X 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, transmission controllers, and battery management systems.
For engineers reviewing the SPC58EC80E7QMC0X datasheet, SPC58EC80E7QMC0X pinout, SPC58EC80E7QMC0X application, or SPC58EC80E7QMC0X equivalent, key selection considerations include dual-core lock-step readiness for safety-critical firmware, integrated CAN-FD and Ethernet AVB support, HSM cryptographic acceleration, and eLQFP176 package compatibility with automotive PCB thermal constraints.
Technical Context
The SPC58EC80E7QMC0X implements a dual-core delayed lock-step architecture with redundancy checkers and dedicated memory error management (MEMU) for ASIL-B compliance. It integrates two independent PLLs - one for peripheral clock domains and one for FM-modulated computational shell timing - enabling deterministic real-time execution under voltage/temperature variation.
Its crossbar switch (XBAR) supports concurrent ECC-protected access to Flash, SRAM, and peripherals by up to six bus masters, while the Body Cross Triggering Unit (BCTU) synchronizes ADC conversions with eMIOS PWM edges or PIT_RTI timers - critical for closed-loop motor control and sensor sampling alignment.
Key Specifications

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, 32-bit, 320 MHz; 4 MB flash; ASIL-D capable; no integrated Ethernet MAC. | Targets higher-ASIL domains (e.g., brake-by-wire); lacks native 10/100 Ethernet but offers more flexible safety partitioning. | Select when ASIL-D certification is mandatory and Ethernet is handled externally or via companion PHY. |
| Renesas RH850/U2A | 32-bit RXv3 core, 240 MHz; 4 MB flash; ASIL-B certified; 10/100 Ethernet; no HSM or CAN-FD in base config. | Optimized for powertrain with ultra-low-jitter timer subsystem; requires add-on security IP for HSM-equivalent functionality. | Select for legacy RH850 ecosystem migration where CAN FD and Ethernet are secondary requirements. |
Compared with SPC58EC80E7QMC0X, the S32K344 delivers higher compute throughput for complex algorithms but requires external Ethernet PHY and lacks on-die HSM flash; the RH850/U2A offers superior real-time determinism for timing-critical engine control but adds cost and complexity for cryptographic functions.

FAQ
What is the maximum junction temperature rating for SPC58EC80E7QMC0X?
The SPC58EC80E7QMC0X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 stress testing. This allows deployment in under-hood environments such as engine compartments and transmission control modules without derating, provided PCB thermal design meets the eLQFP176 package's θJA = 28.5 °C/W specification.
Does SPC58EC80E7QMC0X support AUTOSAR OS and MCAL?
Yes - STMicroelectronics provides full AUTOSAR 4.3-compliant MCAL drivers (including CAN, LIN, SPI, ADC, PWM, and ETH) and OS integration support for the SPC58EC80E7QMC0X. The dual-core architecture supports both split-core and lock-step AUTOSAR configurations, with pre-certified safety libraries for ASIL-B applications.
How is the Hardware Security Module (HSM) isolated from the main application cores?
The HSM is physically isolated via dedicated bus fabric, separate 176 KB flash and SRAM, and an embedded Cortex-M0+ core that executes only signed, encrypted firmware. Communication with main cores occurs exclusively through defined mailbox registers with hardware-enforced access control - preventing unauthorized data leakage or code injection even under fault conditions.
Can SPC58EC80E7QMC0X operate in single-core mode for non-safety applications?
Yes - the device supports flexible core activation via the Mode Entry Module (MEM). Either e200z420 core can be independently enabled or disabled at boot or runtime; the second core may be powered down to reduce dynamic power consumption in non-safety applications while retaining full peripheral access and real-time responsiveness from the active core.
