The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 28 character lines. Using an extension driver, the device can display up to 80 characters.

The Hitachi HD44780 LCD controller is limited to monochrome text displays and is often used in copiers, fax machines, laser printers, industrial test equipment, and networking equipment, such as routers and storage devices.

Compatible LCD screens are manufactured in several standard configurations. Common sizes are one row of eight characters (8×1), and 16×2, 20×2 and 20×4 formats. Larger custom sizes are made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines. The most commonly manufactured larger configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with expansion chips as a single HD44780 chip can only address up to 80 characters.

Character LCDs use a 16 contact interface, commonly using pins or card edge connections on 0.1 inch (2.54 mm) centers. Those without backlights may have only 14 pins, omitting the two pins powering the light. This interface was designed to be easily hooked up to the Intel MCS-51 XRAM interface, using only two address pins, which allowed displaying text on LCD using simple MOVX commands, offering cost effective option for adding text display to devices.

R/W : Read/Write. 0 = Write to display module, 1 = Read from display module (in most applications reading from the HD44780 makes no sense. In that case this pin can be permanently connected to ground and no processor pins need to be allocated to control it.)

In 8-bit mode all transfers happen in one cycle of the enable pin with all 8 bits on the data bus and the RS and RW pins stable. In 4-bit mode, data are transferred as pairs of 4-bit "nibbles" on the upper data pins, D7-D4 with two enable pulses and the RS and RW pins stable. The four most significant bits (7–4) must be written first, followed by the four least significant bits (3–0). The high/low sequence must be completed each time or the controller will not properly receive further commands.

Selecting 4-bit or 8-bit mode requires careful selection of commands. There are two primary considerations. First, with D3-D0 unconnected, these lines will always appear low (0b0000) to the HD44780. Second, the LCD may initially be in one of three states:

The same command is sent three times, Function Set with 8 bit interface D7-D4 = 0b0011, the lower four bits are don"t care, using single Enable pulses. If the controller is in 4 bit mode the lower four bits are ignored so they can"t be sent until the interface is in a known size configuration.

In all three starting cases the bus interface is now in 8 bit mode, 1 line, 5×8 characters. If a different configuration 8 bit mode is desired an 8 bit bus Function Set command should be sent to set the full parameters. If 4 bit mode is desired 0b0010 should be sent on D7-D4 with a single enable pulse. Now the controller will be in 4 bit mode and a full 4 bit bus Function Set command sequence (two enables with command bits 7-4 and 3–0 on subsequent cycles) will complete the configuration of the Function Set register.

The original HD44780 character generator ROM contains 208 characters in a 5×8 dot matrix, and 32 characters in a 5×10 dot matrix. More recent compatible chips are available with higher resolution, matched to displays with more pixels.
