M37415M4-XXXFP
SINGLE-CHIPS-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37415M4-XXXFP is a single-chip microcomputer de-
signed with CMOS silicon gate technology. It is housed in a
. 80-pin plastic molded QFP. This single-chip microcomputer
is useful for business equipment and other consumer ap-
plications.
In addition to its simple instruction set, the ROM, RAM, and
liD addresses are placed on the same memory map to en-
able easy programming.
This microcomputer is also suitable for applications which
require controlling LCDs and generating DTMF.
