C515A
2 Fundamental Structure
The C515A is fully compatible to the architecture of the standard 8051/C501 microcontroller family.
While maintaining all architectural and operational characteristics of the C501, the C515A
incorporates a 10-bit A/D converter, a timer 2 with capture/compare functions, an on-chip XRAM
data memory, as well as some enhancements in the Fail Save Mechanism unit. Figure 2-1 shows
a block diagram of the C515A.
