DESCRIPTION
The M37207MF-XXXSP/FP and M37207M8-XXXSP are single-chip
microcomputers designed with CMOS silicon gate technology. It is
housed in a 64-pin shrink plastic molded DIP or a 80-pin plastic molded
QFP.
In addition to their simple instruction sets, the ROM, RAM and I/O
addresses are placed on the same memory map to enable easy pro-
gramming.
The M37207MF-XXXSP/FP has a PWM function and an OSD func-
tion, so it is useful for a channel selection system for TV. The fea-
tures of the M37207EFSP/FP are similar to those of the M37207MF-
XXXSP/FP except that these chips have a built-in PROM which can
be written electrically. The difference between M37207MF-XXXSP/
FP and M37207M8-XXXSP are the ROM size, RAM size, ROM size
for display and kinds of character. Accordingly, the following descrip-
tions will be for the M37207MF-XXXSP/FP unless otherwise noted.
