TAILIEUCHUNG - LCD1602-HD44780

The HD44780U dot-matrix liquid crystal display controller and driver LSI displays alphanumerics,Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal displayunder the control of a 4- or 8-bit microprocessor. Since all the functions such as display RAM, charactergenerator, 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. | HD44780U LCD-II Dot Matrix Liquid Crystal Display Controller Driver HITACHI Description The HD44780U dot-matrix liquid crystal display controller and driver LSI displays alphanumerics 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. A single HD44780U can display up to one 8-character line or two 8-character lines. The HD44780U has pin function compatibility with the HD44780S which allows the user to easily replace an LCD-II with an HD44780U. The HD44780U 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 to of the HD44780U is suitable for any portable battery-driven product requiring low power dissipation.
