Product details
Overview
SPC564B74B3B9E0Y from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z4d core, operating up to 120 MHz and delivering 200 MIPs. It integrates 3 MByte on-chip Flash with ECC, 256 KByte SRAM with ECC, dual ADCs (10-bit and 12-bit), six FlexCAN interfaces, Fast Ethernet Controller, and Cryptographic Services Engine (AES-128, CMAC) for secure boot-targeting body control modules in vehicles rated for -40 to 125 °C operation.
For engineers reviewing the SPC564B74B3B9E0Y datasheet, SPC564B74B3B9E0Y pinout, SPC564B74B3B9E0Y application, or SPC564B74B3B9E0Y equivalent, key selection criteria include dual-core timing architecture (e200z4d + e200z0h), safety-critical peripherals (SWT, MPU, memory BIST), CAN/FlexRay/Ethernet coexistence, and ASIL-B-ready diagnostic features for automotive body electronics.
Technical Context
The device implements a dual-core architecture: a high-performance e200z4d core (120 MHz, 200 MIPs) for main application tasks and a dedicated e200z0h core (80 MHz, 75 MIPs) for real-time safety monitoring and background diagnostics. Both cores share access to on-chip memory with ECC protection and are managed by a 16-entry Memory Protection Unit (MPU).
Peripheral integration supports automotive domain consolidation: six independent FlexCAN controllers (64-message buffers each), one dual-channel FlexRay module (128 buffers), Fast Ethernet Controller (MII interface), and eMIOS units enabling synchronized PWM generation and ADC sampling-critical for lighting and actuator control with deterministic timing.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-M7 core (320 MHz), 4 MB Flash, no FlexRay, includes HSE crypto accelerator | Lacks FlexRay but adds PCIe and more CAN FD channels; targets next-gen zonal architectures | Select when migrating to ARM ecosystem or requiring CAN FD over FlexRay |
| Renesas RH850/P1M | 32-bit RXv2 core (240 MHz), 2 MB Flash, 6 FlexCAN, no Ethernet, supports G3-PLC modem interface | Focused on powertrain and chassis; no Fast Ethernet but higher analog integration for motor control | Select for cost-sensitive chassis applications where Ethernet is unnecessary |
Compared with SPC564B74B3B9E0Y, the NXP S32K344 offers higher compute throughput and CAN FD but omits FlexRay and automotive Ethernet; the Renesas RH850/P1M provides stronger motor control peripherals but lacks networking convergence-making SPC564B74B3B9E0Y uniquely suited for legacy FlexRay/Ethernet hybrid gateways.

FAQ
What is the maximum operating frequency and associated performance metric of the primary CPU core?
The primary CPU core is the e200z4d, which operates at up to 120 MHz and delivers 200 MIPs (Million Instructions Per Second). This performance level is validated under AEC-Q100 Grade 1 conditions (-40 to 125 °C) with full memory ECC enabled and all safety monitors active, ensuring deterministic timing for real-time automotive tasks.
Does SPC564B74B3B9E0Y support functional safety certification out of the box?
Yes-SPC564B74B3B9E0Y includes hardware safety mechanisms required for ISO 26262 ASIL-B compliance: lockstep-capable dual-core architecture, memory protection unit (MPU), memory BIST, safety watchdog timer (SWT), clock monitoring unit (CMU), and error-correcting code (ECC) on all on-chip memories. ST provides certified safety manuals and FMEDA reports for integration into certified systems.
How many CAN interfaces does this MCU support, and what buffer depth is allocated per channel?
SPC564B74B3B9E0Y supports up to six independent FlexCAN interfaces, each with 64 message buffers. These buffers are configurable as transmit or receive slots and support mailbox prioritization, timestamping, and automatic retransmission-enabling robust handling of mixed CAN 2.0A/B traffic in body domain networks.
Is Fast Ethernet implemented as a full MAC+PHY or MAC-only interface?
SPC564B74B3B9E0Y implements a full Media Access Controller (MAC) with MII (Media Independent Interface) support only-requiring an external PHY chip for physical layer connectivity. The MII interface provides 4-bit parallel RX/TX data paths, control signals (RX_DV, TX_EN), and management channel (MDIO/MDC), compliant with IEEE 802.3u for 10/100 Mbps operation.
