HD66702/HD66701
(Dot Matrix Liquid Crystal Display Controller/Driver)

Rev. 0.0
Description
The HD66701/2 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.
A single HD66702 can display up to two 20-character lines, and a single HD66701 can display up to two
16-character lines.
The low 3-V power supply of the HD66701/2 is suitable for any portable battery-driven product requiring
low power dissipation.
