Description

This is SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER. MITSUBISHI MICROCOMPUTERS M37212M4, M8 XXXSP, M37212M6 XXXSP, FP M37212EFSP, FP SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER with ON-SCREEN DISPLAY CONTROLLER 1. DESCRIPTION The M37212M6-XXXSP, FP, M37212M4, M8-XXXSP are single-chip microcomputers designed with CMOS silicon gate technology. They have a OSD, I2C-BUS interface, and PWM, so it is useful for a channel selection system for TV. The feature of 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, M8-XXXSP are the ROM size and the RAM size as shown below. Accordingly, the following descriptions will be for M37212M6-XXXSP, FP unless otherwise noted. q OSD function Display characters ................................... 24 characters ! 2 lines (It is possible to display 3lines or more by software) Kinds of characters .............................................
