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.
The fastest instruction at 40 MHz frequency ...................... 100 ns
Single power supply ...................................................... 5V 10 %
Low power dissipation (at 40 MHz frequency) .......125 mW (Typ.)
Interrupts ........................................................... 21 types, 7 levels
Multiple-function 16-bit timer ................................................... 5+3
(three-phase motor drive waveform or pulse motor control wave-
form output)

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.
Serial I/O (UART or clock synchronous) ..................................... 2
10-bit A-D converter ............................................ 8-channel inputs
8-bit D-A converter ............................................ 2-channel outputs
12-bit watchdog timer

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.
Programmable input/output
(ports P0—P11) ......................................................................... 87
Small package [M37754M8C-XXXHP]
•
.................................100-pin fine pitch QFP (read pitch : 0.5 mm)
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.
