Qualified for the engine bay: AEC-Q100 and 125°C junction
The STMicroelectronics SPC560P40L1CEFBR is a 32-bit single-core microcontroller from the SPC56 automotive family, built around the e200z0h Power Architecture core.
256 KB Flash and 64 MHz — what the memory and speed budget buys
With 256 KB of Flash (organized as 256K x 8) and 20 KB of RAM, this MCU can hold a moderate automotive application stack — a CANopen protocol layer, sensor fusion, and a real-time control loop — without external memory. The 64 MHz core clock provides enough headroom for PID loops running at several kilohertz and the DMA engine (listed among the peripherals) can move ADC results or CAN frames without loading the CPU. The 16-channel 10-bit ADC covers the analog inputs typical in a body controller or motor position sensor interface.
CAN, LIN, and the peripheral set for automotive networking
The 37 I/O pins, PWM timers, and watchdog timer (WDT) are configured for load-dump-tolerant designs. An internal oscillator keeps the system running without an external crystal, though the datasheet's clock tree should be reviewed for the CAN bit-timing accuracy target.
Package and footprint: 64-LQFP with 10x10 body
The surface-mount assembly uses standard reflow profiles; no exposed pad is called out on the supplier device package, so thermal dissipation relies on the leadframe and board copper.
