Product Summary

The MC68701U4S-1 is an 8-bit single chip microcomputer unit which significantly enhances the capabilities of the M6800 family of parts. MC68701U4S-1 can be used in production systems to allow for easy firmware changes with minimum delay or it can be used to emulate the MC6801 for software development. MC68701U4S-1 includes an upgraded M6800 microprocessor unit with upward source and object code compatibility. Execution times of key instructions have been improved and several new instructions have been added including an unsigned multiply. The MC68701U4S-1 MCU can function as a monolithic microcomputer or can be expanded to a 64K byte address space.
