Product details
Overview
SPC58NH92C5RMI0X from STMicroelectronics is a triple-core AEC-Q100 qualified automotive MCU based on Power Architecture e200z4 cores, operating at 200 MHz with 10 MB on-chip Flash (10240 KB code + 256 KB data), 1088 KB general-purpose SRAM, and ASIL-D safety compliance per ISO 26262. It integrates HSM security, dual Ethernet controllers (10/100 Mbps + 10/100/1000 Mbps), 16 CAN-FD interfaces, and dual FlexRay for domain controller and ADAS gateway applications.
For engineers reviewing the SPC58NH92C5RMI0X datasheet, SPC58NH92C5RMI0X pinout, SPC58NH92C5RMI0X application, or SPC58NH92C5RMI0X equivalent, key selection criteria include triple-core lockstep execution, 10 MB Flash partitioning for FOTA, end-to-end ECC across crossbar and memory subsystems, and hardware support for AUTOSAR-compliant safety mechanisms including FCCU, MEMU, and CRC units.
Technical Context
The SPC58NH92C5RMI0X implements a triple-e200z4 core architecture with one lockstep checker channel, VLE instruction encoding, single-precision floating-point units, and LSP DSP acceleration on all three cores. Each core has 32 KB instruction RAM, 64 KB data RAM, 16 KB I-Cache, and 8 KB D-Cache.
Its dual PLL system provides independent clock domains: PLL0 for peripherals and PLL_ETH for Ethernet MAC timing; the crossbar switch enables concurrent access to Flash, SRAM, and peripherals with end-to-end ECC protection. The HSM module includes 224 KB dedicated Flash (192 KB code + 32 KB data) and complies with EVITA Full security requirements.

FAQ
What is the maximum junction temperature rating for SPC58NH92C5RMI0X?
The SPC58NH92C5RMI0X is rated for operation up to 125 °C junction temperature (TJ), validated per AEC-Q100 Grade 1 specifications. Thermal derating begins above 105 °C ambient, and the device includes an on-die temperature sensor with ±2.5 °C accuracy across −40 °C to 125 °C for real-time thermal monitoring and throttling.
Does SPC58NH92C5RMI0X support AUTOSAR 4.x and 5.x configurations?
Yes - the SPC58NH92C5RMI0X is fully compatible with AUTOSAR Classic Platform 4.3 and Adaptive Platform 19-11 through ST's SPC5 Studio IDE and certified MCAL drivers. Its Nexus Class 3+ debug interface, memory protection units (SMPU), and ASIL-D safety mechanisms meet AUTOSAR requirements for both platforms.
How is Flash partitioning implemented for FOTA use cases?
SPC58NH92C5RMI0X uses hardware-assisted Flash context switching between two independent 5120 KB code partitions. The Boot Assist Flash (BAF) enables secure boot validation, while the Flash controller supports simultaneous read-from-one-partition and program-to-another - allowing background OTA updates without halting application execution.
What external components are required for HSM cryptographic operations?
No external components are required: the HSM integrates AES-128/256, SHA-256, and RSA-2048 accelerators, TRNG, and 224 KB dedicated Flash. Secure key storage uses fuse-based OTP and volatile key registers protected by bus encryption - meeting EVITA Full and UNECE R155 CSMS requirements without external secure elements.
