SBN6400G

64-COMMON driver for dot-matrix STN LCD

Description

The SBN6400G is 64-COMMON driver, designed to be paired with the SBN0064G 64-SEGMENT driver to drive a dot-matrix STN LCD panel.

Functionally, the SBN6400G includes 64 COMMON drivers, on-chip RC oscillator, a 64-bit bi-directional shift register, and timing generation circuit. The RC oscillator needs only an external resistor and capacitor. The timing generation circuit generates clocks and display control signals for both the SBN6400G and the SBN0064G.

To expand COMMON number, the SBN6400G can be cascaded in master-slave connection.

Features:

• To be paired with the SBN0064G 64-SEGMENT driver.
• 64-COMMON STN LCD drivers.
• Master Mode and Slave Mode for cascaded connection to expand COMMON numbers.
• On-chip RC oscillator; only an external resistor and an external capacitor are needed.
• Provides clocks and display control signal to the SBN0064G.
