Product details
Overview
SPC58EC80E5QMC0X 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. It integrates 384 KB general-purpose SRAM, 64-channel eDMA, 8 MCAN interfaces with ISO CAN-FD support, and dual-channel FlexRay for powertrain and chassis control systems.
For engineers reviewing the SPC58EC80E5QMC0X datasheet, SPC58EC80E5QMC0X pinout, SPC58EC80E5QMC0X application, or SPC58EC80E5QMC0X equivalent, key selection criteria include dual-core lock-step capability, HSM cryptographic acceleration, ASIL-B safety architecture (FCCU, MEMU, CRC), and multi-protocol connectivity (CAN-FD, FlexRay, Ethernet 10/100 Mbps with IEEE 1588 timestamping).
Technical Context
The SPC58EC80E5QMC0X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers per core, enabling real-time fault detection for ASIL-B compliance. Its crossbar switch (XBAR) supports concurrent access to Flash, SRAM, and peripherals with end-to-end ECC protection across all memory and bus paths.
It features two independent PLLs: PLL0 provides stable clock domains for peripherals and system logic, while PLL1 delivers FM-modulated clocks for computational shell timing. The HSM includes dedicated 176 KB flash (144 KB code + 32 KB data) and hardware cryptographic co-processing for secure boot and runtime key management.
