Fundamental Structure
The C868 is fully compatible to the architecture of the standard 8051 microcontroller
family. While maintaining all architectural and operational characteristics of the 8051, the
C868 incorporates a CPU with 8 datapointers, a 8-bit A/D converter, a 16-bit capture/
compare unit, a 16 bit timer 2 that can be used as baudrate generator, an interrupt
structure with 2 priority levels, built-in PLL with a fixed factor of 15 and a variable divider,
an XRAM data memory as well as some enhancements in the Fail Save Mechanism
Unit. Figure 2-1 shows a block diagram of the C868.
