DescriptionThe M37754M8C-XXXGP is a single-chip microcomputer designed with high-performance CMOS silicon gate technology. This is housed in a 100-pin plastic molded QFP.
M37754M8C-XXXGP 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 M37754M8CXXXGP 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.
The differences between M37754M8C-XXXGP, M37754M8C-XXXHP, M37754S4CGP and M37754S4CHP 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 M37754M8CXXXGP unless otherwise noted.
