STMicroelectronics SPC584C74E5FMC1X

Overview

SPC584C74E5FMC1X 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. It integrates 384 KB general-purpose SRAM, 64-channel eDMA, 8 MCAN interfaces with ISO CAN-FD support, and a 10/100 Mbps IEEE 802.3-2008 Ethernet controller - deployed in engine control units for real-time combustion management and fault-tolerant powertrain communication.

For engineers reviewing the SPC584C74E5FMC1X datasheet, SPC584C74E5FMC1X pinout, SPC584C74E5FMC1X application, or SPC584C74E5FMC1X equivalent, key selection considerations include dual-core lock-step capability for ASIL-B diagnostics, HSM-based cryptographic acceleration for secure boot, crossbar-switch ECC memory arbitration, and MCAN-FD timing compliance in high-noise powertrain environments.

Technical Context

The device implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers and dedicated Memory Error Management Unit (MEMU) to detect and report memory faults across Flash, SRAM, and peripheral registers. Each e200z420n3 core includes 8 KB I-Cache and 4 KB D-Cache, supports Variable Length Encoding (VLE), and executes single-precision floating-point operations.

Its safety subsystem comprises FCCU for failure notification handling, CRC units for memory/data integrity checking, and end-to-end ECC on XBAR interconnect, Flash, and SRAM arrays. Clocking uses dual PLLs: one for stable peripheral domain timing, another for FM-modulated computational shell operation - enabling deterministic latency for time-critical AUTOSAR modules like STM and RTC/API.

FAQ

What is the maximum junction temperature rating for SPC584C74E5FMC1X?

The SPC584C74E5FMC1X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 requirements. This enables direct placement in high-thermal-load locations such as near engine manifolds or transmission housings without external heatsinking.

Does SPC584C74E5FMC1X support secure boot with cryptographic verification?

Yes - the integrated Hardware Security Module (HSM) includes AES-128/256, SHA-256, and RSA-2048 accelerators that perform signature verification and decryption during Boot Assist Flash (BAF) execution. Secure boot is enforced before main application code loads.

How many CAN-FD interfaces does SPC584C74E5FMC1X provide, and what memory architecture do they use?

The device integrates eight MCAN interfaces compliant with ISO CAN-FD, each with dedicated message RAM and advanced shared memory scheme supporting flexible data rates up to 5 Mbps. Message RAM is partitioned per channel and accessible via XBAR with ECC protection.

Is Ethernet connectivity supported natively, and what IEEE standards are implemented?

Yes - SPC584C74E5FMC1X includes a fully integrated 10/100 Mbps Ethernet MAC compliant with IEEE 802.3-2008, featuring hardware timestamping per IEEE 1588-2008, AVB support (IEEE 802.1AS/802.1Qav), VLAN tag detection (IEEE 802.1Q), and IPv4/IPv6 checksum offload.
