Using an extension driver, the device can display up to 80 characters. The Hitachi HD LCD controller is limited dtaasheet monochrome text displays and is often used in copiersfax machineslaser printersindustrial test equipment, networking equipment, such as routers and storage devices.

Compatible LCD screens are manufactured in several standard configurations. Larger custom sizes 16z2 made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines.

The most commonly manufactured ihtachi configuration is 40×4. Character LCDs use a 16 contact interface, commonly using pins or card edge connections on 0. Those without backlights may have only 14 pins, omitting the two pins powering the light.

The nominal operating voltage for LED backlights 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.

Selecting 4-bit or 8-bit mode datasyeet careful selection of commands. There are two primary considerations. First, with D3-D0 unconnected, these lines will always appear low 0b to the HD when it is in 8-bit mode.

Second, the LCD may initially be in one of three states:. State3 may occur, for example, if a prior control was aborted after sending only the first 4 bits of a command while the LCD was in 4-bit mode. Once in 4-bit mode, character and control data are transferred as pairs of 4-bit “nibbles” on the upper data pins, D7-D4.

The four most significant bits must be written first, followed by the four least significant bits The HD instruction set is shown below: More recent compatible chips are available with higher resolution, matched to displays with more pixels. Two versions of the ROM have been developed: A limited number of custom characters can be programmed into the device in the form of a bitmap using special commands.
