MSM6779

E2B0026-27-Y2 ¡ Semiconductor MSM6779 ¡ Semiconductor 160-DOT SEGMENT DRIVER (TCP) This version: Nov. 1997 MSM6779 Previous version: Mar. 1996 GENERAL DESCRIPTION The MSM6779 is a LCD dot matrix segment driver. Fabricated in CMOS technology, the device consists of 160-bit latches I and II, a 160-bit level shifter, and a 4-level driver. The MSM6779 latches the 4-bit parallel display data sent from a microcontroller or a LCD controller to generate a LCD driving signal. This MSM6779 has a power-save function that sets all the drivers except one to the low supply current status (IDD SBY). This driver's 3V-operation allows significant reduction in current consumption, suitable for battery-driving. The bias voltage to specify a drive level can be supplied externally. The MSM6779 can be used for various types of LCD panels. FEATURES Logic supply voltage : 2.7 V to 5.5 V LCD drive voltage : A wide range from 14 V to 28 V Applicable LCD duty : 1/64 to 1/256 The bias voltage can be supplied externally. LCD outputs : 160 A power-save function to reduce power consumption in a large-screen LCD panel. A 4-bit parallel data transfer to reduces its transfer speed to 1/4 of conventional serial transfer, providing low power consumption. Data transfer clock frequency : 6.5 MHz (VDD=4.5 V) 4.0 MHz (VDD=2.7 V) 35mm-wide-film TCP Tin-plating User area : 8 mm 1/9 ¡ Semiconductor MSM6779 BLOCK DIAGRAM O1 O2 O3 O158 O159 O160 V1L V3L V4L VEEL 160-DOT 4-LEVEL DRIVER VDD VEE...
