Product details
Overview
SPC58EC74E3FMC0X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller featuring dual e200z420n3 cores running at up to 180 MHz, 4 MB on-chip flash (4096 KB code + 128 KB data), hardware security module (HSM), and ASIL-B compliance per ISO 26262 for safety-critical powertrain and chassis control applications.
For engineers reviewing the SPC58EC74E3FMC0X datasheet, SPC58EC74E3FMC0X pinout, SPC58EC74E3FMC0X application, or SPC58EC74E3FMC0X equivalent, this MCU delivers deterministic real-time performance with dual-core lock-step support, integrated Ethernet AVB/TSN readiness, CAN-FD, FlexRay, and comprehensive safety mechanisms including FCCU, MEMU, and CRC units.
Technical Context
The SPC58EC74E3FMC0X implements a dual-issue e200z420n3 CPU architecture with Variable Length Encoding (VLE) for compact code footprint and single-precision floating-point support. It integrates two independent PLLs-one for peripheral clocking and one for FM-modulated computational domains-enabling precise timing isolation across safety-critical subsystems.
Its crossbar switch (XBAR) enables concurrent, end-to-end ECC-protected access to Flash, SRAM, and peripherals by multiple bus masters-including dual CPUs, eDMA, and HSM-while the Body Cross Triggering Unit (BCTU) synchronizes ADC conversions with eMIOS PWM edges or PIT_RTIs for deterministic sensor sampling in closed-loop control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-M7 dual-core, 320 MHz, 4 MB flash, no integrated Ethernet MAC | Lacks native 10/100 Mbps Ethernet with IEEE 1588; relies on external PHY and software timestamping | Select when ARM ecosystem tooling and AUTOSAR Classic/Adaptive compatibility outweigh need for integrated Ethernet AVB |
| Renesas RH850/U2A | 32-bit RXv3 core, 400 MHz, 8 MB flash, ASIL-D ready, no HSM | Higher core frequency but no dedicated hardware security module-requires external secure element for key storage | Select for ultra-high-performance motor control where cryptographic offload is handled externally or via software libraries |
Compared with SPC58EC74E3FMC0X, the NXP S32K344 offers higher clock speed but lacks integrated Ethernet AVB and HSM, while the Renesas RH850/U2A achieves ASIL-D readiness without hardware-enforced crypto acceleration-making the ST part uniquely balanced for Ethernet-connected, safety-certified, and secure automotive gateways.

FAQ
What is the maximum junction temperature rating for SPC58EC74E3FMC0X?
The SPC58EC74E3FMC0X 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 ECUs where ambient temperatures exceed 125 °C.
Does SPC58EC74E3FMC0X support boot from external serial flash?
No-boot is supported only from internal flash memory, including Boot Assist Flash (BAF) for factory programming via asynchronous CAN or LIN/UART. External serial flash boot requires external bootloader implementation and is not natively supported by the ROM boot loader.
How many CAN-FD interfaces does SPC58EC74E3FMC0X integrate?
The SPC58EC74E3FMC0X integrates eight fully compliant MCAN modules supporting ISO CAN-FD (up to 5 Mbps data rate), each with dedicated message RAM and shared memory scheme for flexible filtering and buffering-no external CAN transceivers are required for physical layer interfacing.
Is the Ethernet controller capable of IEEE 1588 Precision Time Protocol (PTP)?
Yes-the integrated 10/100 Mbps Ethernet MAC supports IEEE 1588-2008 hardware timestamping with a 64-bit internal timer, enabling sub-microsecond synchronization accuracy for time-sensitive networking (TSN) applications such as ADAS sensor fusion and distributed control loops.
