SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 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.
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 M37754M8C-
XXXGP 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.
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 M37754M8C-
XXXGP unless otherwise noted.
