STMicroelectronics SPC560P40L1BEFBY

Overview

SPC560P40L1BEFBY 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 safety port up to 8 Mbit/s), LINFlex, DSPI, 10-bit ADC with <1 µs conversion time, and fail-safe features including NMI, programmable watchdog, and fault collection unit.

For engineers reviewing the SPC560P40L1BEFBY datasheet, SPC560P40L1BEFBY pinout, SPC560P40L1BEFBY application, or SPC560P40L1BEFBY equivalent, key selection criteria include ECC-protected memory architecture, ASIL-B-capable safety features, LQFP64 package compatibility, and support for CAN FD-ready timing via safety port configuration.

Technical Context

The device 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 64 KB data flash (4×16 KB banks) for EEPROM emulation - both with ECC.

Real-time peripheral coordination is enabled by a 120-interrupt INTC, 16-channel eDMA, and Cross Triggering Unit (CTU) linking ADC sampling with PWM events. Safety enforcement relies on dedicated hardware: Fault Collection Unit (FCU), non-maskable interrupt (NMI), and Nexus Class 1 debug interface for trace and fault analysis.

FAQ

What is the maximum operating frequency and voltage range for SPC560P40L1BEFBY?

The SPC560P40L1BEFBY operates at up to 64 MHz CPU frequency. Its I/O supply (VDD_HV_IOx) supports 3.0–5.5 V, and its ADC reference supply (VDD_HV_REG) accepts 3.0–5.5 V, with absolute maximum ratings of –0.3 V to 6.0 V. These ranges are validated per ST's Doc ID 16100 Rev 7, Section 3.4.

Does SPC560P40L1BEFBY support CAN FD?

No, SPC560P40L1BEFBY implements FlexCAN 2.0B Active only, supporting up to 1 Mbit/s standard CAN frames. It does not include CAN FD protocol logic or extended data length handling. The safety port operates at up to 8 Mbit/s but remains constrained to CAN 2.0B frame format and arbitration rules.

How is ECC implemented across memory blocks?

ECC is implemented separately for each memory block: 256 KB code flash uses SEC-DED (Single Error Correction, Double Error Detection) with dedicated hardware controller; 20 KB SRAM applies byte-level ECC with automatic correction on read; 64 KB data flash employs sector-level ECC with background scrubbing. All are enabled at power-on reset without software initialization.

What debug interface does SPC560P40L1BEFBY provide?

The device integrates Nexus Class 1 Development Interface (NDI) with 5-pin serial trace output, supporting real-time instruction trace, data watchpoints, and exception capture. It complies with IEEE-ISTO 5001-2003 and is compatible with Lauterbach TRACE32 and iSystem winIDEA debug tools for ASIL-B development workflows.
