HD66702 Datasheet Dot-matrix Liquid Crystal Display Controller/driver

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: .. HD66702 (Dot Matrix Liquid Crystal Display Controller/Driver).

General Description

The HD66702 dot-matrix liquid crystal display controller and driver LSI displays alphanumerics, 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 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.

Key Features

  • 5 × 7 and 5 × 10 dot matrix possible.
  • 80 × 8-bit display RAM (80 characters max. ).
  • 7,200-bit character generator ROM  160 character fonts (5 × 7 dot)  32 character fonts (5 × 10 dot).
  • 64 × 8-bit character generator RAM  8 character fonts (5 × 7 dot)  4 character fonts (5 × 10 dot).
  • 16-common × 100-segment liquid crystal display driver.
  • Programmable duty cycles  1/8 for one line of 5 × 7 dots with cursor  1/11 for one line of 5 × 10 dot.
