Fundamental Structure
The C508 is fully compatible with the architecture of the standard 8051/C501
microcontroller family. While maintaining all architectural and operational characteristics
of the C501, the C508 incorporates a CPU with eight datapointers, a 10-bit A/D
Converter, a 16-bit Capture/Compare Unit, a Timer 2 with capture/compare functions, an
improved interrupt structure with four priority levels, built-in PLL with a fixed factor of 2,
and an XRAM data memory, as well as some enhancements in the Fail Save Mechanism
Unit. Figure 2-1 shows a block diagram of the C508 microcontroller.
