DESCRIPTION
The M37212M4-XXXSP, M37212M6-XXXSP/FP are single-chip mi-
crocomputers designed with CMOS silicon gate technology. It is
housed in a 52-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 M37212M6-XXXSP/FP has a PWM output function and a OSD
display function, so it is useful for a channel selection system for TV.
The feature of the M37212EF-XXXSP/FP and the M37212EFSP/FP
are similar to those of the M37212M6-XXXSP/FP except that these
chips have a built-in PROM which can be written electrically. The
differences between the M37212M6-XXXSP/FP and M37212M4-
XXXSP are the ROM size and the RAM size as shown below. Ac-
cordingly, the following descriptions will be for M37212M6-XXXSP/
FP unless otherwise noted.
