Features

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 with.
