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)
80-pin plastic QFP (QFP80-P-1420-0.80-BL) (Product name: MSM6222B-xxGS-BL)
(Product name: MSM6222B-xxGS-L)
