ST7773

262K Color Single-Chip TFT Controller/Driver

1. Introduction

ST7773 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 528 source line and 220 gate

line driver circuits. This chip can be connected to a microprocessor direct through Serial Peripheral Interface (SPI) or

8-bits/9-bits/16-bits/18-bits parallel interface. The display data is stored in the on-chip Display Data RAM (DDRAM) of

176x220x18 bits. It can perform display data RAM read/write operation with no external operation clock to minimize power

consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to

make a display system with fewer components.
