The HD44780U 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 or 8 bit 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.

Features:

1. 5 x 8 and 5 x 10 dot matrix possible 2. Low power operation support: 2.7 to 5.5V 3. Wide range of liquid crystal display driver power: 3.0 to 11V 4. Correspond to high speed MPU bus interface 2 MHz (when VCC = 5V) 5. 4-bit or 8-bit MPU interface enabled 6. 80 x 8-bit display RAM (80 characters max.) 7. 9,920-bit character generator ROM for a total of 240 character fonts
