STMicroelectronics SPC564B64L7C800Y

Overview

SPC564B64L7C800Y 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-bit and 12-bit), six FlexCAN interfaces, Fast Ethernet Controller, and Cryptographic Services Engine (AES-128). It targets body electronics control units requiring functional safety compliance and real-time deterministic performance.

For engineers reviewing the SPC564B64L7C800Y datasheet, SPC564B64L7C800Y pinout, SPC564B64L7C800Y application, or SPC564B64L7C800Y equivalent, key selection criteria include ASIL-B capable safety features (SWT, MPU, memory BIST), CAN/FlexRay/Ethernet connectivity for domain controllers, and dual-core timing support (e200z4d + e200z0h) for segregated real-time tasks.

Technical Context

This MCU implements a dual-core architecture: a high-performance e200z4d core (120 MHz, 200 MIPs) for main application execution and a dedicated e200z0h core (80 MHz, 75 MIPs) for safety monitoring, communication stack handling, or background diagnostics. Both cores share memory protection via a 16-entry MPU and benefit from ECC-protected Flash/SRAM/Data Flash.

The peripheral set is optimized for automotive body domain integration: six FlexCAN modules (64 buffers each), one dual-channel FlexRay controller (128 buffers), Fast Ethernet Controller (MII interface), and eMIOS with 64 channels supporting synchronized PWM generation and ADC triggering - enabling precise lighting and actuator control with hardware-coordinated timing.

FAQ

What is the maximum operating frequency of the primary core in SPC564B64L7C800Y?

The primary e200z4d core operates at up to 120 MHz, delivering 200 MIPs of processing performance. This frequency is sustained under full load within the −40 °C to +125 °C operating temperature range and specified 3.3 V or 5 V supply conditions, as validated in Section 3.4 of the datasheet (DocID17478 Rev 9).

Does SPC564B64L7C800Y support hardware-based functional safety mechanisms?

Yes - it integrates multiple hardware safety features including a Safety System Watchdog Timer (SWT), 16-entry Memory Protection Unit (MPU), ECC on Flash/SRAM/Data Flash, Clock Monitoring Unit (CMU), and Memory Built-In Self-Test (BIST). These meet requirements for ASIL-B decomposition per ISO 26262 Part 5 Annex D.

Can SPC564B64L7C800Y operate with both 3.3 V and 5 V supply rails?

Yes - the device supports single-supply operation at either 3.3 V or 5 V, with internal voltage regulation and external ballast transistor support. Electrical characteristics for both configurations are fully specified in Tables 10 and 11 (Recommended Operating Conditions), and VDD_BV options are configurable via NVUSRO register bits.

Which debug interface does SPC564B64L7C800Y provide in the LQFP176 package?

The LQFP176 variant supports Nexus 1 debug interface via standard JTAG pins (TCK/TMS/TDI/TDO), enabling boundary scan, flash programming, and real-time trace. Nexus 3+ is exclusive to LBGA256 packages and not available on this LQFP176 variant, as confirmed in Section 3.19.3 of the datasheet.
