STMicroelectronics SPC560P40L3CEFAR

Overview

SPC560P40L3CEFAR from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 256 KB on-chip Flash (ECC-protected), 20 KB SRAM (ECC-protected), and 64 MHz CPU clock, designed for chassis and safety-critical systems including electronic braking and steering control. It integrates dual FlexCAN 2.0B interfaces (one configurable as a safety port up to 8 Mbit/s), LINFlex, DSPI, FlexPWM, and a 10-bit ADC with <1 µs conversion time.

For engineers reviewing the SPC560P40L3CEFAR datasheet, SPC560P40L3CEFAR pinout, SPC560P40L3CEFAR application, or SPC560P40L3CEFAR equivalent, key selection considerations include ECC-protected memory architecture, ASIL-B-capable fault collection unit (FCU), Nexus Class 1 debug support, and dual CAN with safety port capability for ISO 26262-compliant chassis domain controllers.

Technical Context

The SPC560P40L3CEFAR implements a single-issue e200z0h core compliant with Power Architecture® embedded category and supports Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes 256 KB main Flash with erase/program controller and ECC, plus 64 KB data Flash (4 × 16 KB banks) for EEPROM emulation - both accessible via crossbar switch (XBAR) with deterministic latency.

Real-time peripheral coordination is managed by an integrated Cross Triggering Unit (CTU), enabling synchronized ADC sampling with FlexPWM outputs and eTimer events. The interrupt system routes 120 sources through a 16-level priority INTC, with dedicated hardware support for fail-safe operation including non-maskable interrupt (NMI), programmable watchdog timer (SWT), and Fault Collection Unit (FCU) for error logging and safe state entry.

FAQ

What is the maximum operating frequency and core architecture of the SPC560P40L3CEFAR?

The SPC560P40L3CEFAR operates at up to 64 MHz using the e200z0h 32-bit CPU core compliant with Power Architecture® embedded category. It supports Variable Length Encoding (VLE) to reduce code size by ~30% versus standard encoding, improving Flash utilization in safety-critical firmware.

Does the SPC560P40L3CEFAR support functional safety standards like ISO 26262?

Yes - it includes hardware safety mechanisms required for ASIL-B compliance: ECC on Flash and SRAM, Fault Collection Unit (FCU), programmable software watchdog timer (SWT), non-maskable interrupt (NMI), and Nexus Class 1 debug interface for runtime trace and fault analysis.

How many CAN interfaces does the SPC560P40L3CEFAR support, and what are their capabilities?

It supports two FlexCAN 2.0B interfaces, each with 32 message buffers. One can be configured as a safety port capable of up to 8 Mbit/s at 64 MHz - physically isolated with dedicated CAN_H/CAN_L pins and independent buffer management for fail-operational redundancy.

What package type and pin count does the SPC560P40L3CEFAR use?

The SPC560P40L3CEFAR uses a 100-pin LQFP package (14 × 14 × 1.4 mm), with 64 general-purpose I/Os multiplexed across dedicated peripheral functions including CAN, LIN, DSPI, FlexPWM, and ADC inputs - fully documented in ST's Doc ID 16100 Rev 7.
