Product details
Overview
SPC574K72E5C6FAR from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture® automotive MCU featuring dual e200z4 CPU cores in lockstep (2624 KB flash, 64 KB SRAM), one e200z2 I/O processor with LSP APU for DSP, GTM122 timer (88 channels), triple MCAN (2× CAN-FD + 1× TTCAN), 10/100 Ethernet, FlexRay, and mixed-signal ADC subsystem (4× 12-bit SAR + 2× 16-bit Sigma-Delta) - deployed in engine control units and safety-critical powertrain systems.
For engineers reviewing the SPC574K72E5C6FAR datasheet, SPC574K72E5C6FAR pinout, SPC574K72E5C6FAR application, or SPC574K72E5C6FAR equivalent, key selection criteria include lockstep CPU redundancy, CAN-FD/TTCAN coexistence, GTM-based real-time motor timing, and integrated EEPROM emulation for ASIL-B software storage.
Technical Context
The device implements a dual-core lockstep architecture where two e200z4 CPUs execute identical instructions with cycle-by-cycle comparison to detect transient faults - essential for ISO 26262 ASIL-D compliance in powertrain control. The dedicated e200z2 I/O processor offloads peripheral management and supports LSP APU instructions for fast filtering and FFT-like operations in sensor preprocessing.
Its GTM122 module contains three programmable multi-threaded timer cores with 26 KB SRAM and hardware acceleration for spark/fuel injection timing, valve control, and rotor position tracking - synchronized via shared memory with the main CPUs and MCAN/FlexRay interfaces for deterministic latency under 1 µs.
Key Specifications

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 lockstep, 4 MB flash, no integrated FlexRay or TTCAN | Targets chassis and ADAS domains; lacks native TTCAN for time-triggered brake networks | Select when ARM toolchain compatibility and higher flash density outweigh need for FlexRay/TTCAN |
| Renesas RH850/U2A | 32-bit RXv3 core, 3 MB flash, 2× CAN-FD but no Ethernet or FlexRay | Focused on body electronics and gateway functions; limited real-time timer capability vs. GTM122 | Select for cost-sensitive body control modules where Ethernet and FlexRay are unnecessary |
Compared with SPC574K72E5C6FAR, S32K344 offers broader ARM ecosystem support but omits FlexRay and TTCAN required for brake-by-wire; RH850/U2A provides strong CAN-FD performance but lacks the GTM's deterministic timing precision needed for engine control.

FAQ
What is the maximum operating junction temperature for SPC574K72E5C6FAR?
The maximum operating junction temperature is 150 °C, validated per AEC-Q100 Grade 0 qualification. Thermal derating begins above 125 °C ambient in eTQFP144 package, with θJA = 32 °C/W measured per JEDEC JESD51-2. This rating supports under-hood deployment in turbocharged engine compartments.
Does SPC574K72E5C6FAR support bootloading over LIN or CAN only?
Yes - Boot Assist Flash (BAF) supports serial bootloader activation exclusively via asynchronous CAN or LINFlexD interfaces, as specified in Section 1.5 of DocID023601 Rev 6. UART is not supported for factory programming; secure boot authentication uses embedded hash verification before code execution.
How many independent clock domains does the GTM122 module use?
GTM122 operates with three independent clock domains: one for global timer management (GTM_CLK), one for each of its two programmable timer cores (TOM_CLK and ATOM_CLK), and a fourth for its dedicated 26 KB SRAM interface. These domains are synchronized via hardware handshake logic to prevent metastability during cross-domain signal transfers.
Is the 16-bit Sigma-Delta ADC calibrated at production?
Yes - each 16-bit Sigma-Delta ADC undergoes full-scale gain and offset calibration during final test, with coefficients stored in one-time-programmable (OTP) memory. Runtime self-calibration is supported via internal reference injection, achieving ±0.5 LSB INL over -40°C to 150°C after calibration.
