1 / 128 page  ST Sitronix ST7773 262K Color Single-Chip TFT Controller/Driver Ver. 2.0 1 2008-7-7 1. Introduction ST7773 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 528 source line and 220 gate line driver circuits. This chip can be connected to a microprocessor direct through Serial Peripheral Interface (SPI) or 8-bits/9-bits/16-bits/18-bits parallel interface. The display data is stored in the on-chip Display Data RAM (DDRAM) of 176x220x18 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 RAM On-chip Display Data RAM (i.e. Frame Memory) - 176 x 220 x 18 = 696,960 bits LCD Driver Output Circuits: - Source Outputs: 176 RGB channels - Gate Outputs: 220 channels Display Resolution - 176 (RGB) x 220 Display Colors (Color Mode) - Full Color: 262K, RGB=(666) max., Idle Mode OFF - Color Reduce: 8-color, RGB=(111), Idle Mode ON Programmable Pixel Color Format (Color Depth) for Various Display Data input Format - 12-bit/pixel: RGB=(444) using whole frame memory - 16-bit/pixel: RGB=(565) using whole frame memory - 18-bit/pixel: RGB=(666) using whole frame memory Various Interfaces - Parallel 8080-series MCU Interface (8-bit, 9-bit, 16-bit & 18-bit) - 3-line serial interface Display Features - Programmable partial display duty - Line inversion, frame inversion - Supporting MVA type LC - Support both normal-black & normal-white LC Built-in Circuits - DC/DC converter - Adjustable VCOM - 4 preset gamma curves (1.0, 1.8, 2.2 & 2.5) - Oscillator for display clock generation - Timing controller Built-in NV Memory for LCD Initial Register Setting - 7-bits for ID2 - 7-bits for VCOM adjustment Wide Supply Voltage Range - I/O Voltage (VDDI to DGND): 1.6V~3.3V - Analog Voltage (VDD to AGND): 2.7V~3.3V On-Chip Power System - Source Voltage (GVDD to AGND): 3.0V~5.0V - VCOM HIGH level (VCOMH to AGND): 2.5V to 5.0V - VCOM LOW level (VCOML to AGND): -2.5V to 0.0V - Gate driver HIGH level (VGH to AGND): +10.0V to 16V - Gate driver LOW level (VGL to AGND): -13V to -5.5V Operating Temperature: -30°C to +85°C ST7773 8080 MCU Interface: 8-bit/9-bit/16-bit/18-bit Serial Peripheral Interface : 3-line Sitronix Technology Corp. reserves the right to change the contents in this document without prior notice |
