SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER
with ON-SCREEN DISPLAY CONTROLLER
DESCRIPTION
The M37210M3-XXXSP/FP is a single-chip microcomputer designed
with CMOS silicon gate technology. It is housed in a 52-pin shrink
plastic molded DIP or a 64-pin plastic molded QFP. This single-chip
microcomputer is useful for the channel selection system for TVs
because it provides PWM function, OSD display function and so on.
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 features of the M37210E4-XXXSP/FP and the M37210E4SP/FP
are similar to those of the M37210M4-XXXSP except that these
chips have a built-in PROM which can be written electrically.
The differences between the M37210M3-XXXSP/FP, the M37210
M4-XXXSP, and the M37211M2-XXXSP are the ROM size, the RAM
size, and the PWM outputs as shown below. Accordingly, the follow-
ing descriptions will be for the M37210M3-XXXSP/FP unless other-
wise noted.

to “0” because the internal RAM of the M37211M2-XXXSP is
in only the zero page.
