It is housed in a 32-pin shrink plastic molded DIP. The M37471M2-XXXSP/FP is a single-chip mi- crocomputer 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 equip- ment 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 dissi- pation 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.
