SBN0064G

64-SEGMENT driver for dot-matrix STN LCD

Description

The SBN0064G is a 64-SEGMENT driver with 64-row x64 column (4096-bit) on-chip Display Data Memory. It is designed to be paired with the SBN6400G 64-COMMON driver to drive a STN LCD panel.

The on-chip Display Data Memory is for storing display data. Dot-matrix mapping method is used. A "0" stored in the Display Data Memory bit corresponds to an OFF-pixel on the LCD panel; a "1" stored in the Display Data Memory bit corresponds to an ON-pixel on the LCD panel.

Display on the LCD panel is controlled by a host microcontroller. The interface between the host microcontroller and the SBN0064G is composed of 8-bit, bi-directional data bus (DB0~DB7) and control signals R/W, E, and C/D.

The SBN0064G does not have oscillator circuit. It depends on the SBN6400G to supply clocks (CLK1, CLK2) and display control signals (CL, M, FRM).
