262K Color Single-Chip TFT Controller/Driver

1. Introduction

The ST7712 is a single-chip which generates 396 Source lines and 132 gate lines controller/driver for 262K color TFT dot

graphic display. ST7712 support 18-bit high-speed bus interface and Serial Peripheral Interface (SPI), thus it can perform

bi-operation functions, data transfer, and high-speed RAM write function. Display data can be stored in an on-chip display

data RAM of 132x396x6 bits. It can perform display data RAM read/write operation without external operating clock to

minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is

possible to make a display system with the fewest components.
