C502
The SAB-C502-L/C502-2R described in this document is compatible with the SAB 80C52 and can
be used for all present SAB 80C52 applications.
The SAB-C502-2R contains a non-volatile 16 K
8 read-only program memory, a volatile 256
8
read/write data memory, four ports, three 16-bit timers/counters, a six source, two priority level
interrupt structure, a serial port and versatile fail save mechanisms. The SAB-C502-L/C502-2R
incorporates 256
8 additional on-chip RAM called XRAM. For higher performance eight
datapointers are implemented. The SAB-C502-L is identical, except that it lacks the program
memory on chip. Therefore the term SAB-C502 refers to both versions within this specification
unless otherwise noted.
