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 external clock input frequency as shown below. Therefore, the following descriptions will be for the M37702M2AXXXFP unless otherwise noted.
