Notes:
1. All voltages are based on VDD = 0V.
2. The following condition must always hold true with voltages V1, V2, V3, V4 and V5:VDD V1 V2 V3 V4V5
3. The LSI may be permanently damaged if used with any value in excess of the absolute maximum ratings. During normal operation, the LSI should preferably be used within the specified electrical characteristics. Failure to meet them can cause the LSI to malfunction or lose its reliability.
4. Generally, flat package LSIs may have moisture resistance lowered when solder dipped. In mounting LSIs on a board,it is recommended to use a method which is least unlikely to give thermal stress on the package resin.

Description

The SED1520 is a dot matrix LCD driver LSI intended for display of characters and graphics. The bit-addressable display data, which is sent from a microcomputer, is stored in a built-in display data RAM and generates the LCD drive signal.

The SED1520 incorporates innovative circuit design strategies to assure very low current dissipation and a wide range of operating voltages. With these features, the SED1520 permits the user to implement high-performance handy systems operating from a miniature battery.

In order for the user to adaptively configure his system, the SED1520 family offers two application forms. 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 to be achieved by using a minimum number of drivers.
