Product Summary

The M66500FP is a large-scale integrated circuit chip for programmable high-speed I/O intergace, manufactures using a Bi-CMOS process and is suitable for 8-and 16-bit high speed CPU I/O ports. The M66500FP is oprated by a single 5V power supply and consists of three sets of 8-bit I/O ports, twp sets of 8-bit high-withstand voltage output-only ports, and one 4-bit input-only port. The applications of the M66500FP include I/O port expander for microprocessors.
