STMicroelectronics SPC560P40L3BEABY

Overview

SPC560P40L3BEABY from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 320 KB Flash (256 KB code + 64 KB data flash), 20 KB ECC-protected SRAM, and dual FlexCAN interfaces-including a safety port capable of 8 Mbit/s at 64 MHz-designed for chassis control and airbag systems in ISO 26262-compliant safety-critical applications.

For engineers reviewing the SPC560P40L3BEABY datasheet, SPC560P40L3BEABY pinout, SPC560P40L3BEABY application, or SPC560P40L3BEABY equivalent, key selection considerations include its LQFP100 package with 64 GPIOs, 10-bit ADC with <1 µs conversion time and CTU cross-triggering, FlexPWM with 8 outputs synchronized to ADC, and Nexus Class 1 debug support for real-time safety verification.

Technical Context

The SPC560P40L3BEABY implements a single-issue e200z0h CPU core compliant with Power Architecture® embedded category and supports Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes ECC-protected 256 KB on-chip code flash, 64 KB data flash for EEPROM emulation, and 20 KB SRAM-all hardened for automotive temperature range (–40°C to 125°C) and ASIL-B readiness.

It integrates fail-safe features including programmable watchdog timer, non-maskable interrupt, and Fault Collection Unit (FCU) for error logging. The peripheral set includes two LINFlex channels, three DSPI controllers, two FlexCAN modules (one configured as safety port), one 10-bit ADC with 16 input channels, and an eTimer unit with quadrature decode and double-buffered capture/compare.

Key Specifications

FAQ

What is the maximum operating frequency and core architecture of the SPC560P40L3BEABY?

The SPC560P40L3BEABY 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) for improved code density and reduced Flash footprint-critical for constrained automotive firmware images.

Does the SPC560P40L3BEABY support functional safety certification per ISO 26262?

Yes-the device includes hardware safety features required for ASIL-B compliance: ECC-protected memory, Fault Collection Unit (FCU), programmable watchdog timer with windowed mode, and a dedicated safety port FlexCAN with independent clock and message RAM. These are documented in ST's SPC560P Functional Safety Manual (UM1719).

How many CAN interfaces does the SPC560P40L3BEABY provide, and what are their capabilities?

The SPC560P40L3BEABY integrates two FlexCAN 2.0B Active modules. One operates as a standard CAN interface; the second is configurable as a safety port supporting up to 8 Mbit/s at 64 MHz, with separate message buffers, error counters, and clock domain-enabling dual-redundant or safety-critical CAN communication.

What debug and programming interfaces are supported by the SPC560P40L3BEABY?

The device supports Nexus Class 1 debug interface for real-time trace, breakpoint, and fault injection, plus JTAG (IEEE 1149.1) for boundary scan and programming. It also includes an on-chip Boot Assist Module (BAM) enabling UART or CAN-based firmware updates without external debug hardware.
