GENERAL DESCRIPTION
The ST7735SV 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.
