This is based on the most common Hitachi's HD44780 parallel interface chipset. The HD44780U dot-matrix liquid crystal display controller and driver LSI displays alpha numeric, 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. This LCD display can be easily interfaced to a micro-controller in either 8 bit mode or 4 bit mode depending on the number of micro-controller pins you have to spare. The LCD only displays a text output however this is a user interface for display information about battery power or distance to an object.
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 × 8 dot character fonts and 32 5 × 10 dot character fonts for a total of 240 different character fonts.
The nominal operating voltage for LED back-lights is 5V at full brightness, with dimming at lower voltages dependent on the details such as LED color. Non-LED backlights often require higher voltages.
