8-Bit Single-Chip Microcontroller

The C515C is an enhanced, upgraded version of the SAB 80C515A 8-bit microcontroller which additionally provides a full CAN interface, a SPI compatible synchronous serial interface, extended power save provisions, additional on-chip RAM, 64K of on-chip program memory, two new external interrupts and RFI related improvements. With a maximum external clock rate of 10 MHz it achieves a 600 ns instruction cycle time (1 μs at 6 MHz).
