ST7032
17Cx80S Dot Matrix LCD Controller/Driver
Product Description
The ST7032 dot-matrix liquid crystal display controller and driver LSI displays alphanumeric, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4-/ 8-bit or serial interface microprocessor. 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 ST7032 character generator ROM is extended to generate 256 5x8dot character fonts for a total of 256 different character fonts. The low power supply (2.7V to 5.5V) of the ST7032 is suitable for any portable battery-driven product requiring low power dissipation.
The ST7032 LCD driver consists of 17 common signal drivers and 80 segment signal drivers. The maximum display RAM size can be either 80 characters in 1-line display or 40 characters in 2-line display. A single ST7032 can display up to one 16-character line or two 16-character lines.
No extra drivers can be cascaded .
