E2B0041-27-Y3 ¡ Semiconductor ¡ Semiconductor MSM9000B-xx DOT MATRIX LCD CONTROLLER This version: Nov. 1997 MSM9000B-xx Previous version: Mar. 1996 GENERAL DESCRIPTION The MSM9000B-xx is a dot-matrix LCD control driver which has functions of displaying 12 (5 x 7 dots) characters (2 lines) and 120-dot arbitrators. The MSM9000B-xx is provided with a 16-dot common driver, 60-dot segment driver, Display Data RAM (DDRAM), and Character Generator ROM (CGROM). This device can be controlled with commands entered through the serial interface or parallel interface. The font data in the CGROM can be changed by mask option. Since the MSM9000B-xx has an LCD driving bias generator circuit, LCD bias voltages can be obtained by merely providing a required capacitance externally.
