The M37753M8C-XXXFP is a single-chip microcomputer designed with high-performance CMOS silicon gate technology. This is housed in a 80-pin plastic molded QFP.

M37753M8C-XXXFP, M37753M8C-XXXHP, M37753S4CFP and M37753S4CHP have a CPU and a bus interface unit. The CPU is a 16-bit parallel processor, M37753M8C-XXXFP, M37753M8C-XXXHP, M37753S4CFP and M37753S4CHP 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 M37753M8CXXXFP 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.

M37753M8C-XXXFP, M37753M8C-XXXHP, M37753S4CFP and M37753S4CHP include the ROM, RAM, multiple-function timers, motor control function, serial I/O, A-D converter, D-A converter, and so on.

The differences between M37753M8C-XXXFP, M37753M8C-XXXHP, M37753S4CFP and M37753S4CHP are listed in the table on the next page: the internal ROM, usable processor mode, and package. Therefore, the following descriptions will be for the M37753M8CXXXFP unless otherwise noted.
