The C515C is a derivative of the C500 family of 8-bit-microcontrollers with new peripherals. It combines the well known functionality of the standard 80C515A microcontroller with enhanced features.
The C515C features a SPI compatible interface and a CAN module which meets version 2.0B of the Controller Area Network specification.
The high peripheral performance and the CAN feature is ideal for automotive and industrial control applications. Due to EMC/RFI enhancements and power consumption reduction this design excels especially for car radio applications.
