Product details
Overview
SPC560C50L3B4E0X from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z0h core, operating at 64 MHz with 60 DMIPs performance and Variable Length Encoding (VLE). It integrates 512 KB Code Flash with ECC, 64 KB Data Flash with ECC, and 48 KB SRAM with ECC, and targets body electronics control in vehicles requiring ASIL-B compliance support.
For engineers reviewing the SPC560C50L3B4E0X datasheet, SPC560C50L3B4E0X pinout, SPC560C50L3B4E0X application, or SPC560C50L3B4E0X equivalent, key selection criteria include its dual-supply capability (3.3 V/5 V), six FlexCAN 2.0B interfaces, time-triggered I/O with 56-channel PWM/MC/IC/OC support, and dedicated lighting diagnostic module with PWM-synchronized ADC measurements.
Technical Context
This MCU implements a deterministic real-time architecture with 16 priority-level interrupt controller, non-maskable interrupt (NMI), and up to 34 external interrupts including 18 wakeup lines. Its clock system combines four oscillators - FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz) - plus software-controlled FMPLL and Clock Monitor Unit (CMU) for robust timing supervision.
The peripheral set includes six FlexCAN controllers (each with 64 message objects), four LINFlex/UART modules, three DSPI/I²C interfaces, a 10-bit ADC with up to 36 channels (extendable to 64 via external mux), and a Cross-Triggering Unit (CTU) enabling synchronized ADC sampling with PWM events for lighting diagnostics.
