STMicroelectronics SPC560B54L5C6E0X

Overview

SPC560B54L5C6E0X 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 768 KB on-chip Code Flash with ECC, 64 KB Data Flash with ECC, and 96 KB SRAM with ECC, and targets body electronics control in vehicles requiring ASIL-B capable processing, CAN/LIN communication, and PWM-synchronized diagnostics.

For engineers reviewing the SPC560B54L5C6E0X datasheet, SPC560B54L5C6E0X pinout, SPC560B54L5C6E0X application, or SPC560B54L5C6E0X equivalent, key selection criteria include its LQFP144 package with 121 GPIOs, dual ADC subsystem (10-bit + 12-bit, up to 53 channels), 6 FlexCAN 2.0B interfaces, and dedicated lighting diagnostic module supporting time-triggered PWM and CTU-synchronized measurements.

Technical Context

This MCU implements a deterministic real-time architecture with an 8-channel periodic interrupt timer, 4-channel system timer, watchdog, and RTC-all synchronized via a shared clock tree. Its eMIOS unit provides 64 programmable 16-bit timed I/O channels supporting PWM, input capture, output compare, and quadrature decoding, with 10 independent counter bases for flexible timing resource allocation.

The cross-triggering unit (CTU) enables hardware-coordinated sampling between ADCs and PWM generators, while the dedicated lighting diagnostic module integrates advanced PWM generation, fault injection logic, and ADC synchronization-enabling ISO 26262-compliant LED driver control without CPU intervention during critical timing windows.
