Product details

Overview

SPC58EC80C3QMC1X from STMicroelectronics is a dual-core AEC-Q100 qualified automotive MCU based on Power Architecture e200z420n3 CPUs, operating at up to 180 MHz, with 4 MB on-chip flash (4096 KB code + 128 KB data), 384 KB general-purpose SRAM, and hardware security module (HSM) supporting ASIL-B compliance per ISO 26262. It integrates 8 MCAN interfaces with ISO CAN-FD, dual-channel FlexRay, 10/100 Mbps Ethernet with IEEE 1588 timestamping, and is deployed in engine control units (ECUs) for real-time powertrain management.

For engineers reviewing the SPC58EC80C3QMC1X datasheet, SPC58EC80C3QMC1X pinout, SPC58EC80C3QMC1X application, or SPC58EC80C3QMC1X equivalent, key selection criteria include dual-core lock-step safety architecture, HSM cryptographic acceleration, crossbar-switched memory access with end-to-end ECC, and support for AUTOSAR-compliant real-time OS scheduling across distributed vehicle networks.

Technical Context

The SPC58EC80C3QMC1X implements two e200z420n3 cores in delayed lock-step with redundancy checkers, each with 8 KB I-cache and 4 KB D-cache, and supports Variable Length Encoding (VLE) for reduced code footprint. Its crossbar switch enables concurrent access to Flash, SRAM, and peripherals by multiple bus masters, all protected by end-to-end ECC.

It features a comprehensive ASIL-B safety subsystem including FCCU for failure notification handling, MEMU for memory error reporting, CRC units for data integrity, and BCTU for deterministic ADC triggering synchronized to eMIOS/PIT events-enabling time-critical sensor sampling in closed-loop control loops.
