ST ST7735R 262K Color Single-Chip TFT Controller/Driver 1 Introduction The ST7735R 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-bit/9-bit/16-bit/18-bit 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 RAM Built-in Circuits On-chip Display Data RAM (i.e. Frame Memory) DC/DC converter 132 (H) x RGB x 162 (V) bits Adjustable VCOM generation Non-volatile (NV) memory to store initial register setting LCD Driver Output Circuits: Oscillator for display clock generation Source Outputs: 132 RGB channels Factory default value (module ID, module version, etc) are Gate Outputs: 162 channels stored in NV memory Common electrode output Timing controller Display Colors (Color Mode) Built-in NV Memory for LCD Initial Register Setting Full Color: 262K, RGB=(666) max., Idle Mode OFF 7-bits for ID2 Color Reduce: 8-color, RGB=(111), Idle Mode ON 8-bits for ID3 7-bits for VCOM adjustment Programmable Pixel Color Format (Color Depth) for Various Display Data input Format Wide Supply Voltage Range 12-bit/pixel: RGB=(444) using the 384k-bit frame memory I/O Voltage (VDDI to DGND): 1.65V~3.7V (VDDI VDD) and LUT Analog Voltage (VDD to AGND): 2.3V~4.8V 16-bit/pixel: RGB=(565) using the 384k-bit frame memory On-Chip Power System and LUT 18-bit/pixel: RGB=(666) using the 384k-bit frame memory Source Voltage (GVDD to AGND): 3.0V~4.5V and LUT VCOM level (VCOM to AGND): -0.4V to -2.0V Gate driver HIGH level (VGH to AGND): +10.0V to +15V Various Interfaces Gate driver LOW level (VGL to AGND): -13V to -7.5V Parallel 8080-series MCU Interface (8-bit, 9-bit, 16-bit & 18-bit) Operating Temperature: -30C to +85C Parallel 6800-series MCU Interface (8-bit, 9-bit, 16-bit & 18-bit) 3-line serial interface 4-line serial interface Display Features Support both normal-black & normal-white LC Software programmable color depth mode Parallel Interface: 8080,6800(8-bit/9-bit/16-bit/18-bit) ST7735R Serial Interface: 3-line, 4-line Sitronix Technology Corp. reserves the right to change the contents in this document without prior notice.
