DESCRIPTION
GSM7980 Since all the functions such as display RAM, character generator, and liquid crystal driver, required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this controller/driver. The GSM7980 character generator ROM is extended to generate 208 5 x 8 dot character fonts and 32 5 x 10 dot character fonts for a total of 240 different character fonts. The low power supply (2.7V to 5.5V) of the GSM7980 is suitable for any portable battery-driven product requiring low power dissipation. The GSM7980 LCD driver consists of 16 common signal drivers and 40 segment signal drivers which can extend display size by cascading segment driver GSM788E, GSM798E or GSM793E. The maximum display size can be either 80 characters in 1-line display or 40 characters in 2-line display. A single GSM7980 can display up to one 8-character line or two 8-character lines. FEATURES
