Product details
Overview
SPC574K72E5C6FAY 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 (88 channels), designed for engine control units (ECUs) and safety-critical motor control systems.
For engineers reviewing the SPC574K72E5C6FAY datasheet, SPC574K72E5C6FAY pinout, SPC574K72E5C6FAY application, or SPC574K72E5C6FAY equivalent, key selection considerations include AEC-Q100 qualification, triple CAN-FD/TTCAN support, 12-bit/16-bit ADC subsystem, and eTQFP144 package compatibility with cold-start 3.0–5.5 V operation.
Technical Context
This MCU implements a fault-tolerant dual-core architecture where two e200z4 CPUs execute identical instructions in lockstep with hardware comparator monitoring, enabling ASIL-D capable safety mechanisms. The dedicated e200z2 I/O processor handles peripheral offload and supports LSP-APU DSP instructions for real-time signal processing.
The GTM122 module integrates three fine-grain multi-threaded timer cores with 26 KB SRAM and hardware acceleration for engine timing, PWM generation, and safety-related time-triggered tasks. Dual MCAN interfaces support ISO CAN-FD up to 5 Mbps, while the third MCAN complies with TTCAN for deterministic time-triggered communication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Dual e200z4 (VLE-compliant, lockstep), plus e200z2 I/O processor - enables functional safety via hardware-checked redundancy and peripheral offload. |
| Flash Memory | 2624 KB on-chip flash with 64 KB EEPROM emulation - supports robust firmware storage and parameter retention without external EEPROM. |
| RAM | 64 KB general-purpose SRAM + 112 KB CPU-local RAM - sufficient for real-time control stacks and safety monitor buffers. |
| Analog Converters | 1× 12-bit SAR supervisor ADC + 4× fast 12-bit SAR ADCs + 2× 16-bit Sigma-Delta ADCs - enables simultaneous high-speed and high-precision sensing (e.g., crankshaft position + current sensing). |
| Timer System | GTM122 with 88 channels (24 input, 64 output) and 3 programmable timer cores - delivers cycle-accurate engine timing, variable-frequency PWM, and safe torque control. |
| Communication | 3× MCAN (2× CAN-FD, 1× TTCAN), 5× LINFlexD, 5× DSPI, 1× 10/100 Mbps Ethernet, 2× FlexRay - meets full ECU connectivity requirements for modern vehicle domains. |
| Supply Voltage | Single 5 V ±10% supply, cold-start capable down to 3.0 V - ensures reliable boot and operation during battery dip conditions in automotive environments. |

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-M7 dual-core, 8 MB flash, no integrated GTM; uses SENT/PSI5 instead of Sigma-Delta ADCs. | Better suited for software-defined vehicle architectures requiring AUTOSAR Adaptive; lacks native engine timing hardware acceleration. | Select when migrating to ARM ecosystem or requiring Linux-capable real-time OS support. |
| Renesas RH850/P1M | 32-bit RXv2 core, 4 MB flash, 1.5 MB RAM; includes GPTA timer but no lockstep CPU; supports CAN FD only (no TTCAN/FlexRay). | Optimized for body electronics and infotainment gateways; limited safety certification scope (ASIL-B max). | Select for cost-sensitive body control modules where full ASIL-D capability is not required. |
Compared with SPC574K72E5C6FAY, the S32K344 offers higher flash density and ARM toolchain familiarity but lacks GTM-based deterministic timing; the RH850/P1M provides larger RAM and lower active power but omits TTCAN and lockstep enforcement needed for powertrain safety integrity.

FAQ
What is the maximum junction temperature rating for SPC574K72E5C6FAY?
The device is rated for maximum junction temperature of +150 °C under continuous operation, validated per AEC-Q100 stress test conditions. Thermal derating begins above +125 °C ambient, and the built-in temperature sensor (±2.5 °C accuracy) enables real-time thermal monitoring for safety shutdown logic.
Does SPC574K72E5C6FAY support flash programming in-circuit via JTAG or SWD?
No - it uses Nexus Class 3 debug interface (IEEE-ISTO 5001) instead of JTAG/SWD. Flash programming is supported via Boot Assist Flash (BAF) using asynchronous CAN or LIN/UART, or through Nexus-enabled debug probes like Lauterbach TRACE32 for development and calibration.
How many independent clock domains does the GTM122 timer support?
The GTM122 integrates three independent programmable timer cores (TOM, ATOM, and SERC), each with its own clock input, prescaler, and local 26 KB SRAM. This allows concurrent execution of engine timing, motor control PWM, and safety watchdog functions without resource contention.
Is the 16-bit Sigma-Delta ADC calibrated at factory, and can it be re-calibrated in-system?
Yes - each 16-bit Sigma-Delta ADC undergoes full-scale and offset calibration during final test. In-system recalibration is supported via dedicated CALIB command register and reference voltage injection, enabling drift compensation during vehicle lifetime without external equipment.
