ST7789V2规格书详情
GENERAL DESCRIPTION
The ST7789V2 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 can directly connect to an external microprocessor,
and accepts, 8-bits/9-bits/16-bits/18-bits parallel 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.
