STMicroelectronics SPC560C50L3C6E0Y

Overview

SPC560C50L3C6E0Y from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 512 KB ECC-protected code flash, 64 KB data flash, and 48 KB SRAM. It integrates six FlexCAN 2.0B interfaces, four LINFlex/UARTs, three DSPI/I²C channels, and a 10-bit ADC with up to 36 channels-designed for body electronics control units requiring ASIL-B compliance and extended temperature operation (−40 to 125 °C).

For engineers reviewing the SPC560C50L3C6E0Y datasheet, SPC560C50L3C6E0Y pinout, SPC560C50L3C6E0Y application, or SPC560C50L3C6E0Y equivalent, key selection considerations include CAN message object count (64 per interface), VLE instruction set support for code density, clock redundancy (FXOSC/SXOSC/FIRC/SIRC), and dedicated lighting diagnostic module with time-triggered PWM and CTU-synchronized ADC.

Technical Context

This MCU implements a dual-oscillator clock system with hardware-managed FMPLL, clock monitor unit (CMU), and ultra-low-power standby mode retaining RTC, SRAM, and CAN monitoring. Its interrupt architecture supports 16 priority levels, NMI, and up to 34 external interrupts-including 18 wakeup-capable lines.

The peripheral set includes six-channel periodic interrupt timers, four-channel system timer module, software watchdog, real-time clock, and 16-bit counter time-triggered I/Os supporting PWM, motor control, input capture, and output compare across up to 56 channels-with ADC diagnostics enabled via cross-triggering unit (CTU).

FAQ

What is the maximum operating frequency and associated performance metric?

The SPC560C50L3C6E0Y operates at a maximum frequency of 64 MHz, achieving up to 60 DMIPs (Dhrystone MIPS). This performance level supports real-time execution of ASIL-B-compliant control algorithms, including PWM-based motor sequencing and multi-sensor data fusion within strict timing budgets.

Does this MCU support functional safety certification out of the box?

While the SPC560C50L3C6E0Y includes hardware safety features-ECC on flash/SRAM, MPU, clock monitoring, and NMI-it requires system-level implementation per ISO 26262 to achieve ASIL-B. ST provides safety manuals and FIT rate data, but certification depends on end-application design and toolchain qualification.

How many CAN interfaces does it support, and what is their compliance level?

The device integrates six FlexCAN interfaces compliant with ISO 11898-1 (CAN 2.0B Active), each supporting 64 message objects. All channels operate concurrently at bit rates up to 1 Mbps, enabling full-vehicle network participation as node, gateway, or zone controller without external CAN controllers.

What debug interface is available, and is it accessible on the LQFP100 package?

The SPC560C50L3C6E0Y features Nexus1 debug capability on all packages, including LQFP100. This provides real-time trace, hardware breakpoints, and memory access via JTAG. Nexus2+ is only available on LBGA208 emulation packages and is not present on this LQFP100 variant.
