SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37702M2AXXXFP is a single-chip microcomputers
designed with high-performance CMOS silicon gate technology.
This is housed in a 80-pin plastic molded QFP. This single-chip
microcomputer has a large 16 M bytes address space, three in-
struction queue buffers, and two data buffers for high-speed
instruction execution. The CPU is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. This
microcomputer is suitable for office, business, and industrial
equipment controller that require high-speed processing of large
data.
The differences between M37702M2AXXXFP, M37702M2BXXXFP,
M37702S1AFP and M37702S1BFP are the ROM size and the ex-
ternal clock input frequency as shown below. Therefore, the
following descriptions will be for the M37702M2AXXXFP unless
otherwise noted.

typewriters, facsimiles, word processors, and personal computers
Control devices for industrial equipment such as ME, NC, commu-
nication and measuring instruments.
NOTE
Refer to “Chapter 5 PRECAUTIONS” when using this microcom-
puter.
The M37702M2AXXXFP and M37702S1AFP satisfy the timing
requirements and the switching characteristics of the former
M37702M2-XXXFP and M37702S1FP.
