Product Summary

The R6501Q is an One-Chip Microprocessor. The R6501Q is a complete, high performance 8-bit NM08-3 microcomputer on a single chip and is compatible with all members of the R6500 family. The R6501Q consists of an enhanced 6502 CPU, an internal clock oscillator, 192 bytes of Random Access Memory (RAM), and versatile interface circuitry. The interface circuitry includes two-16-bit programmable timer/counters, 32 bidirectional input/output lines (including four edge-sensitive lines and input latching on one 8-bit port), a full-duplex serial I/O channel, ten interrupts, and bus expandability.
