Product details

Overview

SPC560B50L3C4E0X 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/UART channels, three DSPI/I²C peripherals, and a dedicated lighting diagnostic module for body electronics control in door modules, seat controllers, and lighting ECUs.

For engineers reviewing the SPC560B50L3C4E0X datasheet, SPC560B50L3C4E0X pinout, SPC560B50L3C4E0X application, or SPC560B50L3C4E0X equivalent, key selection criteria include CAN message object count (64 per interface), temperature grade (–40 to 125 °C), LQFP100 package compatibility, and hardware-level PWM-synchronized ADC diagnostics for lighting control systems.

Technical Context

This MCU implements a variable-length encoding (VLE) Power Architecture® core delivering up to 60 DMIPs, with an 8-entry memory protection unit (MPU) and Nexus1 debug interface standard across all packages. Its clock system combines FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz) oscillators with software-controlled FMPLL for flexible domain-specific frequency synthesis.

The peripheral set includes a 16-bit counter time-triggered I/O subsystem supporting up to 56 PWM/MC/IC/OC channels, cross-triggered by the CTU for synchronized ADC sampling, and a dedicated lighting diagnostic module enabling time-triggered fault detection and advanced PWM generation for LED driver control.
