Product details
Overview
SPC574K72E7C6FAY from STMicroelectronics is an AEC-Q100 qualified 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 for engine/motor control. It includes 3 MCAN interfaces (2 ISO CAN-FD, 1 TTCAN), 10/100 Mbps Ethernet, dual FlexRay, and enhanced ADC subsystem with 4×12-bit SAR + 2×16-bit Sigma-Delta converters - deployed in powertrain ECUs and advanced driver assistance systems (ADAS) domain controllers.
For engineers reviewing the SPC574K72E7C6FAY datasheet, SPC574K72E7C6FAY pinout, SPC574K72E7C6FAY application, or SPC574K72E7C6FAY equivalent, key selection criteria include lockstep CPU safety compliance, GTM122 hardware timing support for real-time motor control, CAN-FD/TTCAN coexistence, and dual-core VLE instruction set compatibility with AUTOSAR BSW layers.
Technical Context
The device implements a dual-core lockstep architecture with two e200z4 CPUs sharing instruction and data caches (4 KB I-Cache / 2 KB D-Cache), each backed by dedicated local SRAM (16 KB iSRAM + 64 KB dSRAM). The auxiliary e200z2 I/O processor supports DSP workloads via LSP APU instructions and operates with its own 16 KB iSRAM and 48 KB dSRAM.
System-level timing is managed by the GTM122 module - a multi-threaded, fine-grain programmable timer with 88 channels (24 input, 64 output), 26 KB dedicated SRAM, and hardware acceleration for engine ignition, fuel injection, and safety-critical PWM generation per ISO 26262 ASIL-D requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Dual e200z4 (VLE-compliant, lockstep), plus e200z2 I/O processor - enables ASIL-D fault detection via hardware redundancy and independent safety monitor path. |
| Flash Memory | 2624 KB on-chip flash with EEPROM emulation (64 KB) - supports field firmware updates without external non-volatile memory. |
| RAM | 64 KB general-purpose SRAM + 112 KB CPU-embedded RAM (16+64+16+48 KB across three cores) - eliminates need for external RAM in compact ECU designs. |
| Timer System | GTM122 with 88 channels, 3 programmable cores, 26 KB SRAM - provides deterministic, cycle-accurate timing for up to 16 cylinder engines and multi-motor vector control. |
| Analog Converters | 1×12-bit supervisor SAR + 4×12-bit fast SAR + 2×16-bit Sigma-Delta ADCs - enables simultaneous high-speed current sensing (motor phase) and high-resolution position feedback (resolver). |
| Communication | 3×MCAN (2×CAN-FD, 1×TTCAN), 5×LINFlexD, 5×DSPI, 1×10/100 Ethernet, dual FlexRay - supports time-triggered and event-driven communication in zonal E/E architectures. |
| Power Supply | Single 5 V ±10% supply, cold-start capable down to 3.0 V - simplifies power tree design and eliminates need for secondary bias rails in 12 V automotive systems. |
Pinout & Package
SPC574K72E7C6FAY is packaged in eLQFP176 (24 mm × 24 mm × 1.4 mm), a thermally enhanced, AEC-Q200 qualified lead-free package with 176 pins and 0.4 mm pitch. Pin assignments are defined per STMicroelectronics DocID023601 Rev 6, Section 2.1–2.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| CLKIN | External oscillator input | Accepts 4–40 MHz crystal or CMOS clock source for FMPLL - primary timing source for all system clocks including CAN-FD bit rate generation. |
| TXD0/RXD0 | LINFlexD0 UART channel | Full-duplex LIN/UART interface supporting LIN 2.2A and ISO 9141-2 protocols - used for diagnostic bootload and ECU configuration during vehicle assembly. |
| MCAN0_TX/MCAN0_RX | CAN-FD physical layer interface | Differential transceiver pins for first CAN-FD channel - supports data rates up to 5 Mbps and payload lengths up to 64 bytes for OTA update distribution. |
| GTM_TOUT0_0 | GTM output channel | Programmable PWM output from GTM122 core 0 - delivers sub-microsecond jitter timing for IGBT gate drivers in traction inverters. |

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 DSPI instead of DSPI+FlexRay | Targets chassis domain with strong functional safety but lacks hardware-accelerated motor control timing | Select when migrating to ARM ecosystem or requiring larger flash for OTA stacks; not drop-in for GTM-dependent timing code. |
| Renesas RH850/U2A | 32-bit RXv3 core, 2 MB flash, 128 KB RAM, supports CAN-FD but no TTCAN or Ethernet | Focused on body electronics and gateway applications; limited real-time motor control capability | Choose for cost-sensitive body control modules where Ethernet and TTCAN are unnecessary; requires redesign of GTM timer logic. |
Compared with SPC574K72E7C6FAY, the S32K344 offers higher flash density and ARM toolchain alignment but lacks GTM122's deterministic timing for engine control, while the RH850/U2A provides lower power consumption in sleep modes but omits Ethernet and TTCAN required for next-gen ADAS domain integration.

FAQ
What is the maximum operating junction temperature for SPC574K72E7C6FAY?
The maximum junction temperature is +150 °C, validated per AEC-Q100 Grade 0 qualification. Thermal derating begins at +125 °C ambient under full CPU and GTM load, with thermal resistance θJA = 28.5 °C/W for eLQFP176 package. Operation above 150 °C risks permanent parametric shift in flash retention and ADC offset stability.
Does SPC574K72E7C6FAY support AUTOSAR 4.3 and later?
Yes - ST provides certified AUTOSAR Basic Software (BSW) modules compliant with AUTOSAR 4.3 and 4.4, including MCAL drivers for GTM122, MCAN, LINFlexD, and ADC. The dual e200z4 lockstep architecture is validated for use with AUTOSAR OS Safety Extension and SafeWatch monitoring libraries.
How is EEPROM emulation implemented in the on-chip flash?
ST's Flash EEPROM Emulation (FEE) library allocates 64 KB of the 2624 KB flash for wear-leveling and atomic write operations. It uses a sector-based shadow page mechanism with CRC-32 checksums and rollback recovery, achieving >100,000 write cycles and data retention >10 years at +125 °C junction temperature.
Can the GTM122 module operate independently of the CPU cores?
Yes - GTM122 runs autonomously using its three programmable microcode engines and 26 KB SRAM. It can execute complex timing sequences (e.g., multi-phase PWM bursts, encoder counting, or capture-triggered ADC sampling) without CPU intervention, reducing interrupt load and enabling deterministic response times below 50 ns jitter.
