SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

DESCRIPTION

The M37754M6C-XXXGP and M37754M6C-XXXHP are single-chip

microcomputers designed with high-performance CMOS silicon gate

technology. This is housed in a 100-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 M37754M6C-

XXXGP and M37754M6C-XXXHP has 6 special instructions which

contain instructions for signed multiplication/division; these added in-

structions 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 con-

verter, and so on.
