STMicroelectronics SPC564B64L8C9E0Y

Overview

SPC564B64L8C9E0Y 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 1.5 MByte on-chip Flash with ECC, 256 KByte SRAM with ECC, dual ADCs (10- and 12-bit), six FlexCAN interfaces, Fast Ethernet Controller, and Cryptographic Services Engine (AES-128). Designed for body electronics control units including door modules and lighting controllers.

For engineers reviewing the SPC564B64L8C9E0Y datasheet, SPC564B64L8C9E0Y pinout, SPC564B64L8C9E0Y application, or SPC564B64L8C9E0Y equivalent, key selection considerations include its dual-core timing architecture (e200z4d + e200z0h), safety features (SWT, MPU, memory BIST), automotive-grade temperature range (−40 to 125 °C), and integrated CAN/Ethernet connectivity for distributed vehicle networks.

Technical Context

This MCU implements a dual-core configuration: a high-performance e200z4d core (120 MHz) for real-time control tasks and a dedicated e200z0h core (80 MHz) for background diagnostics and communication stack handling. Both cores share access to on-chip memory protected by ECC and are managed via a 16-entry MPU.

The peripheral set is architected for automotive body domain integration: six FlexCAN controllers (64-message buffers each), 10 LINFlex/UART channels, eight DSPI interfaces, and a dedicated Fast Ethernet Controller supporting MII interface - enabling gateway and domain controller functionality in modern vehicle architectures.

FAQ

What is the maximum operating frequency of the e200z4d core in SPC564B64L8C9E0Y?

The e200z4d core operates at up to 120 MHz under recommended conditions (3.3 V supply, −40 to 125 °C), delivering 200 MIPs performance. This frequency is sustained using the FMPLL with a 4–40 MHz external crystal or internal 16 MHz RC oscillator as reference, and is validated across the full automotive temperature range per AEC-Q100 Grade 1.

Does SPC564B64L8C9E0Y support hardware-based secure boot?

Yes - the integrated Cryptographic Services Engine (CSE) enables secure device boot mode using AES-128 encryption and CMAC authentication. Boot ROM validates signed firmware images before execution, and keys are stored in tamper-resistant memory. This implementation meets EVITA Medium profile requirements and supports ISO/SAE 21434 threat mitigation for ECU boot integrity.

How many CAN interfaces does SPC564B64L8C9E0Y provide, and what is their buffer capacity?

It integrates six FlexCAN controllers, each with 64 message buffers - totaling 384 configurable message objects. Each controller supports CAN 2.0A/B protocols, bit rates up to 1 Mbps, and hardware timestamping. Buffers are allocated dynamically via the Message Buffer Descriptor Table (MBDT), enabling flexible filtering and prioritization for multi-bus body network topologies.

Is Nexus debug supported on the LQFP208 package of SPC564B64L8C9E0Y?

No - Nexus 3+ interface is available only on LBGA256 packages. The LQFP208 variant (including SPC564B64L8C9E0Y) supports Nexus 1, providing basic instruction trace and breakpoint capabilities compatible with standard JTAG debuggers. Full real-time trace and data streaming require Nexus 3+, which is physically routed only on the LBGA256 ball grid array variant.
