GENERAL DESCRIPTION
The ML9040-Axx/-Bxx 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 or 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 ML9040-Axx/-Bxx has the character generator ROM that can be programmed by custom
mask. The ML9040-Axx/-Bxx 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 patterns, uppercase: 5 x 11 dots, 4 patterns).
Built-in oscillation circuit to connect with 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.
