Product details
Overview
SPC564B64L8C9E0X from STMicroelectronics is a 32-bit automotive-grade MCU based on the Power Architecture® e200z4d core, operating up to 120 MHz (200 MIPs), with 1.5 MByte on-chip Flash (ECC), 256 KByte SRAM (ECC), and integrated FlexCAN, DSPI, LINFlex, Ethernet, and CSE cryptographic engine - deployed in body control modules for vehicle lighting, door control, and gateway functions.
For engineers reviewing the SPC564B64L8C9E0X datasheet, SPC564B64L8C9E0X pinout, SPC564B64L8C9E0X application, or SPC564B64L8C9E0X equivalent, key selection criteria include dual-core timing capability (e200z4d + e200z0h), ASIL-B-ready safety features (SWT, MPU, BIST), automotive temperature range (−40 to +125 °C), and LQFP208 package compatibility with CAN/LIN/Ethernet coexistence requirements.
Technical Context
This MCU integrates two independent Power Architecture® cores: a high-performance e200z4d (120 MHz) for main application tasks and a dedicated e200z0h (80 MHz) for real-time safety monitoring and diagnostics. Core coupling is managed via shared memory and inter-core interrupts, not cache coherency.
The peripheral set is architected for automotive body electronics: six FlexCAN controllers (64 buffers each), one Fast Ethernet Controller (MII interface), eight DSPI channels, ten LINFlex/UARTs, and dual ADCs (10-bit + 12-bit) with synchronized PWM sampling - all supported by a configurable clock tree with FMPLL, multiple oscillators (4–40 MHz crystal, 32 kHz aux, 16/128 kHz RC), and Clock Monitoring Unit (CMU).

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC564B70L8C9E0X | 2 MByte Flash (vs. 1.5 MByte), same LQFP208 package and peripheral set | Supports larger AUTOSAR OS images and complex diagnostic stacks requiring extended code space | Select when firmware size exceeds 1.3 MByte or future-proofing for feature expansion is required |
| SPC56EC64L8C9E0X | Same Flash/RAM, but adds e200z4d-only single-core configuration and enhanced EEPROM emulation | Better suited for cost-sensitive entry-level BCMs where dual-core safety monitoring is not mandated | Choose for non-ASIL-B designs needing identical pinout and toolchain compatibility but lower unit cost |

The SPC564B64L8C9E0X features dual Power Architecture® cores: an e200z4d core running up to 120 MHz (200 MIPs) for primary application processing, and an e200z0h core running up to 80 MHz (75 MIPs) for safety monitoring and diagnostics. Both cores operate independently with shared memory and inter-core interrupt signaling.
Does this MCU support AUTOSAR-compliant development environments?
Yes - the SPC564B64L8C9E0X is fully supported by the SPC5 Studio IDE, EB tresos, and Vector DaVinci tools. Its memory protection unit (MPU), Nexus 1 debug interface, and ASIL-B-ready peripherals (SWT, BIST, ECC memory) meet AUTOSAR OS and RTE requirements for BSW module integration and safety certification.
What packaging and thermal specifications apply to the LQFP208 variant?
The SPC564B64L8C9E0X in LQFP208 uses a 28 × 28 × 1.4 mm body with 0.5 mm lead pitch. Thermal resistance (θJA) is 28.5 °C/W under JEDEC JESD51-7 conditions. It supports operation from −40 to +125 °C ambient, with junction temperature limited to +150 °C per AEC-Q100 stress testing.
How does the Cryptographic Services Engine (CSE) function in secure boot?
The CSE implements AES-128 encryption and CMAC authentication to verify signed firmware images during boot. It enforces secure device boot mode by checking digital signatures before loading code into executable memory - preventing unauthorized or corrupted firmware execution, and supporting ISO/SAE 21434 threat mitigation.
