ST7735R
262K Color Single-Chip TFT Controller/Driver
1 Introduction
The ST7735R is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 396 source line and 162
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 162 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.
