DOT MATRIX LCD CONTROLLER WITH 16-DOT COMMON DRIVER AND 40-DOT
GENERAL DESCRIPTION
The MSM6222B-xx is a dot matrix LCD controller which is fabricated in low power CMOS
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.
The MSM6222B-xx is the equivalent of Hitachi's HD44780. There is, however, a slight difference
between the two devices as described in the table on the last page.
The MSM6222B-xx has the character generator ROM that can be programmed by custom mask.
MSM6222B-01 is a standard version having 160 characters with lowercase (5 x 7 dots), and 32
characters with uppercase (5 x 10 dots) in this ROM.
FEATURES
• 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
uppercase (5 x 10 dots).
• Character patterns are programmable by character generator RAM. (Lowercase: 5 x 8 dots,
8 kinds, uppercase: 5 x 11 dots, 4 kinds).
• Oscillation circuit for external resistor or ceralock.
• 1/8 duty (1 line; 5 x 7 dots + cursor), 1/11 duty (1 line; 5 x 10 dots + cursor), or 1/16 duty (2
lines; 5 x 7 dots + cursor), selectable.
• Clear display even at 1/5 bias, 3.0V LCD driving voltage.
• Package options:
80-pin plastic QFP (QFP80-P-1420-0.80-L) (Product name: MSM6222B-xxGS-L)
80-pin plastic QFP (QFP80-P-1420-0.80-BL) (Product name: MSM6222B-xxGS-BL)
xx indicates code number.
