ST7732  
262K Color Single-Chip TFT Controller/Driver  
1. Introduction  
The ST7732 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-bits/9-bits/16-bits/18-bits 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.  
2. Features  
Single chip TFT-LCD controller/driver with display data RAM  
Display resolution: 132 (H) x RGB x 162 (V)  
Display data RAM (frame memory): 132 x 162 x 18-bits = 384,912 bits
