Product details
Overview
SPC574K72E7C6FAR from STMicroelectronics is a 32-bit Power Architecture® automotive MCU featuring dual e200z4 CPU cores in lockstep, 2624 KB on-chip flash, 64 KB general-purpose SRAM, and integrated GTM122 timer with 88 channels for engine/motor control. It includes 3 MCAN interfaces (2 supporting CAN-FD), Ethernet 10/100 Mbps, FlexRay, and AEC-Q100 Grade 1 qualification for under-hood applications.
For engineers reviewing the SPC574K72E7C6FAR datasheet, SPC574K72E7C6FAR pinout, SPC574K72E7C6FAR application, or SPC574K72E7C6FAR equivalent, key selection criteria include lockstep CPU safety architecture, GTM122 timing precision for real-time powertrain control, multi-protocol connectivity (CAN-FD/FlexRay/Ethernet), and cold-start 3.0 V operation capability.
Technical Context
The device implements a dual-core lockstep execution model using two e200z4 VLE-compliant CPUs with shared 16 KB instruction SRAM and 64 KB data SRAM, plus dedicated 4 KB I-Cache and 2 KB D-Cache. The auxiliary e200z2 I/O processor supports DSP via LSP APU instructions and operates with 16 KB instruction SRAM and 48 KB data SRAM.
System-level timing is managed by the GTM122 module - a fine-grained multi-threaded timer with 26 KB dedicated SRAM, hardware acceleration for engine ignition and valve timing, and deterministic response under ASIL-B/D conditions. Dual PLLs provide clock synthesis, including one frequency-modulated PLL for EMI reduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-R52 dual-core, 4 MB flash, no integrated GTM; uses eDMA-based timer subsystem | Lacks hardware-accelerated engine timing engine; requires software-based timing compensation | Preferred when ARM ecosystem tooling and AUTOSAR Classic/Adaptive support are mandatory |
| Renesas RH850/U2A | 32-bit RXv3 core, 2 MB flash, 1.5 MB SRAM; includes GTM-equivalent GPTP but no CAN-FD native support | Requires external CAN-FD transceivers and lacks Ethernet MAC; higher static power consumption | Selected where legacy RH850 software investment and functional safety certification reuse are prioritized |
Compared with SPC574K72E7C6FAR, the S32K344 offers broader ARM toolchain compatibility but lacks GTM-level timing determinism, while the RH850/U2A provides proven safety certification history but requires external components to match full connectivity scope.

FAQ
What is the maximum junction temperature rating for SPC574K72E7C6FAR?
The device is rated for maximum junction temperature of +150°C per AEC-Q100 Grade 1 qualification. Thermal characteristics for eLQFP176 package specify θJA = 26.5°C/W (JEDEC Std-51-2), enabling operation at full performance in ambient temperatures up to +125°C with appropriate PCB copper pour and airflow.
Does SPC574K72E7C6FAR support secure boot and cryptographic acceleration?
Yes - it integrates a Hardware Security Module (HSM) compliant with EVITA Medium profile, supporting AES-128/256, SHA-256, RSA-2048, and TRNG. Secure boot verifies signed firmware images stored in protected flash sectors before execution, meeting UNECE R155 cybersecurity management system requirements.
Can the GTM122 module replace an external FPGA for motor control timing?
Yes - GTM122 provides 88 independent timing channels with hardware state machines, 26 KB dedicated SRAM, and sub-microsecond resolution. It offloads complex PWM generation, dead-time insertion, and encoder quadrature decoding from the CPU, eliminating need for external timing logic in most traction inverter designs.
What debug interfaces are supported, and is JTAG required for production programming?
The device supports Nexus Development Interface (NDI) per IEEE-ISTO 5001-2003 and JTAG (IEEE 1149.1). Production programming uses Boot Assist Flash (BAF) via CAN, LIN, or UART - JTAG is optional for development and failure analysis, not required for manufacturing line flashing.
