Product Summary

The P80C32X2BA is a Single-Chip 8-Bit Microcontroller. It can address up to 64K of external memory. The P80C32X2BA,512 has four 8-bit I/O ports, three 16-bit timer/event counters, a multi-source, four-priority-level, nested interrupt structure, an enhanced UART and on-chip oscillator and timing circuits. For systems that require extra memory capability up to 64k bytes, each can be expanded using standard TTL-compatible memories and logic. The P80C32X2BA also has a more versatile serial channel that facilitates multiprocessor communications.
