MITSUBISHI MICROCOMPUTERS
M37753M6C-XXXFP, M37753M6C-XXXHP
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 M37753M6C-
XXXFP 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 con-
verter, and so on.
