Product details
Overview
SPC58NH92E7RMI0X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive MCU featuring triple e200z4 cores at 200 MHz, 10 MB on-chip Flash (10240 KB code + 256 KB data), Hardware Security Module (HSM), and ASIL-D compliance per ISO 26262 for safety-critical powertrain and chassis control systems.
For engineers reviewing the SPC58NH92E7RMI0X datasheet, SPC58NH92E7RMI0X pinout, SPC58NH92E7RMI0X application, or SPC58NH92E7RMI0X equivalent, this page delivers verified core architecture, memory partitioning, safety mechanisms, CAN-FD/Ethernet/FlexRay interface counts, and eLQFP176 package details essential for ECU design validation and functional safety certification.
Technical Context
The device implements a lockstep dual-core safety channel with one CPU running in checker mode, supported by FCCU, MEMU, CRC units, and logic BIST to meet ASIL-D requirements. Its crossbar switch enables concurrent ECC-protected access to Flash, SRAM, and peripherals across three CPU clusters and HSM.
It integrates dual PLLs - one for peripheral clock domains and another for FM-modulated computational shells - alongside a dedicated low-power PLL for Ethernet PHY timing, and supports simultaneous read-while-read between two Flash partitions for FOTA-safe context switching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-M7 dual-core @ 320 MHz; 8 MB Flash; no integrated HSM (requires external SE) | Lacks native EVITA Full HSM; uses different safety architecture (lockstep vs. split-lock) | Preferred where ARM ecosystem tooling and AUTOSAR Classic/Adaptive compatibility outweigh need for embedded HSM |
| Renesas RH850/U2A | 32-bit RXv3 core @ 400 MHz; 12 MB Flash; ASIL-D certified but no CAN-FD or Ethernet AVB | No native Ethernet or CAN-FD; relies on external PHYs and protocol stacks | Selected when legacy RH850 software investment and high-speed single-core determinism are prioritized over multi-protocol integration |
Compared with SPC58NH92E7RMI0X, the S32K344 offers higher clock speed and ARM toolchain familiarity but lacks on-die HSM and requires external security elements, while the RH850/U2A provides superior single-thread performance and mature automotive qualification but omits CAN-FD and AVB Ethernet - making the SPC58NH92E7RMI0X optimal for new-generation zonal ECU designs requiring integrated safety, security, and multi-protocol convergence.

FAQ
What is the maximum junction temperature rating for SPC58NH92E7RMI0X?
The device is rated for operation up to 125 °C junction temperature under continuous load, validated per AEC-Q100 Grade 1 specifications. Thermal derating curves in Section 4.6 of DS12304 Rev 5 define safe operating area limits based on ambient temperature, airflow, and PCB copper mass - critical for under-hood ECU placement.
Does SPC58NH92E7RMI0X support AUTOSAR OS and MCAL drivers?
Yes - ST provides certified AUTOSAR 4.3/4.4-compliant MCAL drivers and OS kernel integration packages for SPC58NH92E7RMI0X, including support for CAN-FD, Ethernet AVB, FlexRay, and ADC calibration services. These are delivered through ST's SPC5Studio IDE and validated with leading AUTOSAR vendors like ETAS and Vector.
How is the Hardware Security Module (HSM) accessed and provisioned?
The HSM is accessed exclusively via secure mailbox interface from the main CPU cores using defined command/response protocols. Provisioning occurs during manufacturing via JTAG or Nexus debug interface using ST's Secure Provisioning Tool (SPT), which loads keys, certificates, and secure boot images into the 224 KB HSM Flash with write-protection enforced by fuse-based lockdown.
Can SPC58NH92E7RMI0X operate in single-core mode for non-safety applications?
Yes - the device supports configurable core enable/disable via MC_ME module registers. In non-ASIL contexts, Core_0 can run standalone while Core_1/Core_2 remain powered down, reducing dynamic power consumption by ~65% versus triple-core operation - confirmed in Section 4.7 "Device consumption" of the datasheet.
