The C515 is fully compatible to the architecture of the standard 8051/C501 microcontroller family.
While maintaining all architectural and operational characteristics of the C501, the C515
incorporates a 8-bit A/D converter, a timer 2 with capture/compare functions, as well as some
enhancements in the Fail Save Mechanism unit. Figure 2-1 shows a block diagram of the C515.
