Description

The M37207MF-XXXSP/FP and M37207M8-XXXSP are single-chip microcomputers designed with CMOS silicon gate technology. M37207MF-XXXSP/FP and M37207M8-XXXSP are 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 programming.

The M37207MF-XXXSP/FP has a PWM function and an OSD function, so it is useful for a channel selection system for TV. The features of the M37207EFSP/FP are similar to those of the M37207MFXXXSP/ 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 descriptions will be for the M37207MF-XXXSP/FP unless otherwise noted.
