DESCRIPTION

The M37753M6C-XXXFP and M37753M6C-XXXHP are single-chip microcomputers designed with high-performance CMOS silicon gate technology. This is housed in a 80-pin plastic molded QFP.

This microcomputer has a CPU and a bus interface unit. The CPU is a 16-bit parallel processor that can also be switched to perform 8-bit parallel processing, and the bus interface unit enhances the memory access efficiency to execute instructions fast.

In addition to the 7700 Family basic instructions, the M37753M6CXXXFP has 6 special instructions which contain instructions for signed multiplication/division; these added instructions improve the servo arithmetic performance to control hard disk drives and so on. This microcomputer also include the ROM, RAM, multiple-function timers, motor control function, serial I/O, A-D converter, D-A converter, and so on.
