STMicroelectronics SPC560P40L1BEAAY

Overview

SPC560P40L1BEAAY from STMicroelectronics is a 32-bit Power Architecture® e200z0h-based automotive MCU with 256 KB on-chip flash memory (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 units. It integrates dual FlexCAN 2.0B interfaces (one configurable as safety port up to 8 Mbit/s), LINFlex, DSPI, FlexPWM, and a 10-bit ADC with <1 µs conversion time.

For engineers reviewing the SPC560P40L1BEAAY datasheet, SPC560P40L1BEAAY pinout, SPC560P40L1BEAAY application, or SPC560P40L1BEAAY equivalent, key selection criteria include ASIL-B-capable fail-safe features (programmable watchdog, NMI, Fault Collection Unit), Nexus Class 1 debug support, and LQFP64 package compatibility with automotive-grade thermal and ESD robustness (±2 kV HBM).

Technical Context

The SPC560P40L1BEAAY 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 ECC and erase/program controller, plus 64 KB data flash (4 × 16 KB banks) for EEPROM emulation - both featuring error correction and wear-leveling support.

Peripheral integration centers on functional safety: dual FlexCAN controllers (32 message buffers each), one configurable as a dedicated safety port; a 120-interrupt INTC with 16 priority levels; and fail-safe peripherals including programmable watchdog timer (SWT), non-maskable interrupt (NMI), and Fault Collection Unit (FCU) for runtime fault logging and system recovery coordination.

FAQ

What is the maximum operating frequency and core architecture of the SPC560P40L1BEAAY?

The SPC560P40L1BEAAY operates at up to 64 MHz using the e200z0h 32-bit CPU core, compliant with the Power Architecture® embedded category and supporting Variable Length Encoding (VLE). This core delivers deterministic real-time performance with single-issue execution and low-latency interrupt response essential for automotive safety functions.

Does the SPC560P40L1BEAAY support functional safety standards such as ISO 26262?

Yes - the device includes hardware safety mechanisms required for ASIL-B compliance: ECC on flash/SRAM, Fault Collection Unit (FCU), programmable software watchdog timer (SWT), non-maskable interrupt (NMI), and Nexus Class 1 debug interface. These features are documented in ST's safety manual (UM1805) and qualified per ISO 26262 Part 5.

How many CAN interfaces does the SPC560P40L1BEAAY provide, and what are their capabilities?

The SPC560P40L1BEAAY integrates two FlexCAN 2.0B interfaces, each with 32 message buffers. One can be configured as a safety port supporting up to 8 Mbit/s at 64 MHz clock, while the other operates as a standard CAN interface. Both support self-test, loopback mode, and error counters for diagnostic coverage.

What package type and pin count does the SPC560P40L1BEAAY use?

The SPC560P40L1BEAAY uses an LQFP64 package (10 × 10 × 1.4 mm) with 37 general-purpose I/O pins. Pin assignments include dedicated CANH/CANL, LINRX/LINTX, DSPI, FlexPWM, ADC, and system-level signals (RESET, CLKIN, VDD rails), fully detailed in Section 2.1 of the datasheet (Doc ID 16100 Rev 7).
