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 programming. 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 following descriptions will be for the M37210M3-XXXSP/FP unless otherwise noted. |
