1 / 86 page ST Sitronix ST7529 32 Gray Scale Dot Matrix LCD Controller/Driver Ver 1.8 1/85 2007/10/25 1. INTRODUCTION The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components. 2. FEATURES Driver Output Circuits −255 segment outputs / 160 common outputs −Maximum resolution is 255 x 160 Applicable Duty Ratios − Various partial display − Partial window moving & data scrolling Microprocessor Interface − 8/16-bit parallel bi-directional interface with 6800-series or 8080-series −4-line serial interface (write only) −9 bit 3-line serial interface (write only) On-chip Display Data RAM − Capacity : 160 x 255 x 5bit = 204000bits (Max) On-chip Low Power Analog Circuit − On-chip oscillator circuit − Voltage converter (x2, x3, x4, x5, x6, x7, x8) − Voltage regulator − Voltage follower (LCD bias: 1/5, 1/7, 1/9, 1/10, 1/11, 1/12, 1/13, 1/14) Operating Voltage Range − Supply voltage (VDD, VDD1, VDD2, VDD3, VDD4, VDD5): 2.4 to 3.3V − LCD driving voltage (VLCD = V0 - VSS): 3.76 to 18.0V Temperature Gradient Coefficient − -0.130%/℃ LCD driving voltage (EEPROM) − To store contrast adjustment value for better display Package Type − Application for COG and TCP ST7529 6800, 8080, 4-Line, 3-Line interface |
