C504
Functional Description
The C504 basic architecture is fully compatible to the standard 8051 microcontroller family. While
maintaining all architectural and operational characteristics of the SAB 80C52 / C501, the C504
incorporates some enhancements such as on-chip XRAM, A/D converter, fail save mechanisms,
and a versatile capture/compare unit.
Figure 3 shows a block diagram of the C504.
