STMicroelectronics SPC560C50L3C6E0X

Overview

SPC560C50L3C6E0X 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 ECC data Flash, and 48 KB ECC 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 SPC560C50L3C6E0X datasheet, SPC560C50L3C6E0X pinout, SPC560C50L3C6E0X application, or SPC560C50L3C6E0X equivalent, key selection criteria include CAN message object count (64 per interface), temperature range (−40 to +125 °C), LQFP100 package compatibility, and integrated CTU-synchronized PWM/ADC for lighting diagnostics.

Technical Context

The device implements a VLE-enabled e200z0h CPU delivering up to 60 DMIPs, with an 8-entry MPU enforcing memory protection across safety-critical automotive functions. Its clock system combines FXOSC (4–16 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz) sources, managed by a software-controlled FMPLL and monitored by a Clock Monitor Unit (CMU).

Interrupt handling supports 16 priority levels and up to 34 external interrupts-including 18 wakeup-capable lines-while the timer subsystem includes six 32-bit periodic interrupt timers, four 32-bit system timers, RTC, and a software watchdog. The ADC features 36 physical channels (extendable to 64 via external mux), individual conversion registers, and cross-triggering with PWM and CTU for synchronized sampling.

FAQ

What is the maximum CAN bit rate supported by SPC560C50L3C6E0X?

The device supports CAN 2.0B operation up to 1 Mbps per FlexCAN interface. This is achieved using the internal clock tree with FMPLL-derived timing and validated per ISO 11898-2 physical layer requirements. Bit timing registers allow fine-grained configuration for network topology compensation, including propagation and sample point adjustment.

Does SPC560C50L3C6E0X support JTAG debugging in production units?

Yes - it includes full Nexus1 debug support compatible with standard JTAG probes (e.g., Lauterbach TRACE32, PLS UDE). The JTAG interface remains accessible in all operating modes, including RUN and DEBUG, and supports real-time trace, breakpoint setting, and memory inspection without halting CPU execution.

How is functional safety addressed in the memory subsystem?

All memory blocks - 512 KB code Flash, 64 KB data Flash, and 48 KB SRAM - implement end-to-end ECC with single-bit error correction and double-bit error detection. The memory protection unit (MPU) enforces region-based access rights, and Flash programming includes CRC verification and write-protection lock bits per sector.

Can the ADC perform simultaneous sampling across multiple channels?

Yes - the Cross Triggering Unit (CTU) allows hardware-synchronized start-of-conversion across up to 36 ADC channels. This enables true simultaneous sampling for motor phase current measurement or multi-sensor acquisition, with conversion results stored in individual registers and timestamped via system timer.
