The MSM6222B-01 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-01 is the equivalent of Hitachi&锛�39;s HD44780. There is, however, a slight difference
between the two devices as described in the table on the last page.
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
