262K Color Single-Chip TFT Controller/Driver

Introduction

The ST7715 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 396 source line and 132

gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial

Peripheral Interface (SPI), 8-bit/9-bit/16-bit/18-bit parallel interface. Display data can be stored in the on-chip display data

RAM of 132 x 132 x 18 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.
