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.
