This datasheet details the ST7796U, a single-chip TFT controller and driver with 320x480 resolution, 16.7M color support, and frame memory for LCD applications.
The ST7796U is a single-chip controller and driver designed for 262K-color graphic type TFT-LCDs. It integrates 960 source lines and 480 gate lines driving circuits, along with an on-chip frame memory of 320x480x18 bits. The device supports direct connection to external microprocessors via 8/9/16/18-bit parallel interfaces, SPI, and MIPI interfaces, allowing for display data RAM read/write operations without an external clock to minimize power consumption.
