HD66720 - Panel Controller/Driver

General Description

The HD66720 dot-matrix liquid crystal display controller (LCD) and driver LSI incorporates a key-scan function and an LED display function, and displays alphanumeric character and symbols.

A single HD66720 is capable of displaying a single 10-character line or two 8-character lines.

Key Features

  • Control and drive of a dot matrix LCD with built-in scanning.
  • Wide field-of-division display with low duty cycle of 1/9 (1 line) and 1/17 (2 lines).
  • 10-character single line (5 × 8-dot font) and 50-segment display with a single chip (two 8-character line display by setting a register).
  • Maximum 40-character single line display with extension drivers (see list 1).
  • Built-in key scan matrix buffer circuit: 5 × 6 (30 keys) input (at strobe cycle: 5 ms to.

HD66720 (LCD-II/K8) (Panel Controller/Driver for Dot-Matrix Liquid Crystal Display with Key-Matrix) Preliminary Description The HD66720 dot-matrix liquid crystal display controller (LCD) and driver LSI incorporates a key-scan function and an LED display function, and displays alphanumeric character and symbols. A single HD66720 is capable of displaying a single 10-character line or two 8-character lines. In addition, a single line of up to 40 characters can be displayed with extension drivers. Since the HD66720 incorporates a 5 × 6 matrix key scan circuit and two LED drive circuits, it can control front panels of telephone, car stereos, audio equipment, printers, or facsimiles with a single chip.
