Fundamental Structure
The C505 is fully compatible to the architecture of the standard 8051/C501 microcontroller family.
While maintaining all architectural and operational characteristics of the C501, the C505
incorporates a CPU with 8 datapointers, an 8-bit A/D converter, a 4-channel capture/compare unit,
a Full-CAN controller unit (C505C only), an XRAM data memory as well as some enhancements in
the Fail Save Mechanism Unit. Figure 2-1 shows a block diagram of the C505.
