Technical details

For a production BOM that already specifies this order code, the existing allocation is still being fulfilled, but new design-ins should target the official successor or a validated second source.

Automotive-grade 8-bit MCU with CAN

On the peripheral side, it includes a CANbus controller, LINbus, I2C, SPI, and UART/USART interfaces, plus a 16-channel 10-bit ADC, PWM outputs, and a watchdog timer.

Memory and peripheral fit

The 2 KB EEPROM is useful for storing calibration parameters or fault codes that survive power loss without external EEPROM.
