The C868 is a member of the Infineon Technologies C800 family of 8-bit
microcontrollers. It is fully compatible to the standard 8051 microcontroller. Its features
include the capture compare unit (CCU6) which is useful in motor control applications,
extended power saving provisions, on-chip RAM and RFI related improvements. The
C868 has a maximum CPU clock rate of 40MHz. At 40MHz it achieves a 300ns
instruction cycle time.
The C868 basically operates with internal program memory only. The C868-1R contains
8K x 8 on-chip ROM of program memory and the C868-1S contains 8K x 8 of on-chip
RAM of program memory. Different operating modes are provided to allow flexibility in
the access of the different types of memory. An additional RAM, XRAM, is provided for
the implementation of in-system programming.
