HD66712U - Dot-Matrix Liquid Crystal Display Controller/Driver

Download the HD66712U datasheet PDF. This datasheet also covers the HD66712 variant, as both devices belong to the same dot-matrix liquid crystal display controller/driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The HD66712 dot-matrix liquid crystal display controller and driver LSI displays alphanumerics, numbers, and symbols.

It can be configured to drive a dot-matrix liquid crystal display under the control of a serial or a 4- or 8-bit microprocessor.

Key Features

  • 5 × 8 dot matrix possible.
  • Clock-synchronized serial interface capability; can interface with 4- or 8-bit MPU.
  • Low-power operation support:  2.7 to 5.5V (low voltage)  Wide liquid-crystal voltage range: 2.7 to 11.0V max.
  • Booster for liquid crystal voltage  Two/three times (13V max. ).
  • High-speed MPU bus interface (2MHz at 5-V operation) 364 HD66712U.
  • Extension driver interface.
  • Character display and independent 60-icon mark dis.

HD66712U (Dot-Matrix Liquid Crystal Display Controller/Driver) Description The HD66712 dot-matrix liquid crystal display controller and driver LSI displays alphanumerics, numbers, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a serial or 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 minimum system can be interfaced with this controller/driver. A single HD66712 is capable of displaying a single 24-character line, two 24-character lines, or four 12character lines.
