ST7789V3
1 GENERAL DESCRIPTION
The ST7789V3 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720
source line and 320 gate line driving circuits. This chip is capable of connecting directly to an external
microprocessor, and accepts 8-bits/9-bits parallel, SPI, RGB 6bits interface. Display data can be stored in the
on-chip display data RAM of 240x320x18 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
circuit necessary to drive liquid crystal; it is possible to make a display system with the fewest components.
