ML9090-02 Product details

Description

The ML9090-01 and ML9090-02 are LCD drivers that contain internal RAM and a key scan function.

They are best suited for car audio displays.

Since 1-bit data of the display RAM corresponds to the light-on or light-off of 1-dot of the LCD panel (a bit map system), a flexible display is possible.

Features

Logic voltage: VDD 2.7 to 5.5 V.
LCD drive voltage: VBI 6 to 16 V (positive voltage).
80 segment outputs,10 common outputs for ML9090-01 and 18 common outputs for ML909002.
Built-in bit-mapped RAM (ML9090-01: 80.
10 = 800 bits, ML9090-02: 80.
18 = 1440 bits).
4-pin serial interface with CPU: CS, CP, DI/O, KREQ.
Built-in LCD drive bias resistors.
Built-in voltage doubler and tripler circuits.
Built-in 5.
5 key.
