GENERAL DESCRIPTION
1.1
DESCRIPTION
The WE6120 is a dot matrix LCD driver LSI intended for display of characters and graphics. Thebit-addressable display data, which is sent from a microcomputer, is stored in a built-in display dataRAM and generates the LCD drive signal.
The WE6120 incorporates innovative circuit design strategies to assure very low current dissipa-tion and a wide range of operating voltages. With these features, the WE6120 permits the user toimplement high-performance handy systems operating from a miniature battery.
In order for the user to adaptively configure his system, the WE6120 family offers two applicationforms. One form allows an LCD display of 12 characters
×
2 lines with an indicator with a single chip.
The other is dedicated to driving a total of 80 segments, enabling a medium-size display tobe achieved by using a minimum number of drivers.
