GENERAL DESCRIPTION
Character display on the dot matrix character type LCD can be controlled in combination with a 4-bit or 8-bit microcontroller. 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.
