7471 General Description

The 7470/7471 group is a single-chip microcomputer designed with CMOS silicon gate technology. It is housed in a 32-pin shrink plastic molded DIP. The M37471M2-XXXSP/FP is a single-chip microcomputer designed with CMOS silicon gate technology. It is housed in a 42-pin shrink plastic molded DIP or a 56-pin plastic molded QFP.

These single-chip microcomputer are useful for business equipment and other consumer applications.

In addition to its simple instruction set, the ROM, RAM, and I/O addresses are placed on the same memory map to enable easy programming .

The differences between the M37471M2-XXXSP and the M37471M2-XXXFP are the package outline and the power dissipation ability (absolute maximum ratings).

The differences among M37470M2-XXXSP, M37470M4-XXXSP,M37470M8-XXXSP, M37471M2-XXXSP/FP, M37471M4-XXXSP/FP and M37471M8-XXXSP/FP are noted below.
