MSM6222B-xx

SEGMENT DRIVER

The MSM6222B-xx is a dot matrix LCD controller which is fabricated in low power CMOS

The MSM6222B-xx is the equivalent of Hitachi's HD44780. There is, however, a slight difference

The MSM6222B-xx has the character generator ROM that can be programmed by custom mask.

• Easy interface with an 8-bit or 4-bit microcontroller.

• Dot matrix LCD controller/driver for lowercase (5 x 7 dots) or uppercase (5 x 10 dots).

• Automatic power ON reset.

• COMMON signal drivers (16) and SEGMENT signal drivers (40).

• Can control up to 80 characters when used in combination with MSM5259.

• Character generator ROM for 160 characters with lowercase (5 x 7 dots) and 32 characters with

• Character patterns are programmable by character generator RAM. (Lowercase: 5 x 8 dots,

• Oscillation circuit for external resistor or ceralock.

DOT MATRIX LCD CONTROLLER WITH 16-DOT COMMON DRIVER AND 40-DOT

GENERAL DESCRIPTION

silicon gate technology. Character display on the dot matrix character type LCD can be

controlled in combination with a 4-bit/8-bit microcontroller. This LSI consists of 16-dot

COMMON driver, 40-dot SEGMENT driver, display data RAM, character generator RAM,

character generator ROM and control circuit.
