Product details
Overview
SPC584C74E3QEC1X 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 compliance per ISO 26262. It integrates 384 KB general-purpose SRAM, 8 MCAN interfaces with ISO CAN-FD support, and a 10/100 Mbps Ethernet controller compliant with IEEE 802.3-2008 - deployed in engine control units and advanced driver assistance systems (ADAS) domain controllers.
For engineers reviewing the SPC584C74E3QEC1X datasheet, SPC584C74E3QEC1X pinout, SPC584C74E3QEC1X application, or SPC584C74E3QEC1X equivalent, key selection criteria include dual-core lock-step safety architecture, HSM cryptographic acceleration, crossbar-switched memory access with end-to-end ECC, and multi-protocol connectivity (CAN-FD, FlexRay, LIN, Ethernet) for automotive ECU consolidation.
Technical Context
The SPC584C74E3QEC1X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers for ASIL-B fault detection, supported by FCCU, MEMU, and CRC units. Its crossbar switch enables concurrent access to Flash, SRAM, and peripherals from multiple bus masters with full end-to-end ECC protection across data paths.
It features two independent PLLs: one for stable peripheral clock domains and another for FM-modulated computational shell timing. The HSM contains dedicated 176 KB flash (144 KB code + 32 KB data) and executes cryptographic operations independently of main cores, isolating security-critical functions from application software.

FAQ
What is the maximum junction temperature rating for SPC584C74E3QEC1X?
The SPC584C74E3QEC1X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 requirements. This enables deployment in under-hood environments such as engine control modules and transmission control units without derating, provided PCB thermal design meets ST's recommended copper pour and via guidelines for the eTQFP100 package.
Does SPC584C74E3QEC1X support AUTOSAR Classic and Adaptive platforms?
Yes - the SPC584C74E3QEC1X is fully compatible with AUTOSAR Classic R4.x and supports foundational services for AUTOSAR Adaptive (e.g., POSIX-compliant OS abstraction, Ethernet AVB stack, and secure boot). ST provides certified MCAL drivers and SPC5 Studio IDE integration, enabling seamless configuration of CAN-FD, Ethernet, and safety modules per AUTOSAR specifications.
How is the Hardware Security Module (HSM) isolated from the main application cores?
The HSM is physically isolated with dedicated 176 KB flash (144 KB code + 32 KB data), separate bus interface, and independent clock domain. It runs a hardened real-time OS and exposes only authenticated APIs via mailbox registers - preventing direct memory access from main cores. All cryptographic operations (AES-128/256, SHA-256, RSA-2048) execute within the HSM boundary, with keys never exposed to main SRAM or Flash.
Can SPC584C74E3QEC1X operate in low-power modes while maintaining CAN-FD or Ethernet wake-up capability?
Yes - it supports Ultra Low Power Standby mode with RTC and Smart Wake-up Unit (WKPU), enabling wake-up via CAN-FD message filters, LIN header detection, or Ethernet magic packet. In this mode, only the WKPU, RTC, and selected peripheral clocks remain active, achieving sub-100 µA quiescent current while retaining full network responsiveness for vehicle-wide sleep/wake coordination.
