It can be configured to drive a dot-matrix liquid crystal display under the control of a 4 / 8-bit with 6800-series or 8080-series, 3/4-line serial interface microprocessor. Since all the functions such as display RAM, character generator ROM/RAM and liquid crystal driver, required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be used with this controller/driver. The ST7032 character generator ROM size is 256 5x8dot bits which can be used to generate 256 different character fonts (5x8dot). The ST7032 is suitable for low voltage supply (2.7V to 5.5V) and is perfectly suitable for any portable product which is driven by the battery and requires low power consumption. The ST7032 LCD driver consists of 17 common signal drivers and 80 segment signal drivers. The maximum display RAM size can be either 80 characters in 1-line display or 40 characters in 2-line display. A single ST7032 can display up to one 16-character line or two 16-character lines. The ST7032 dot-matrix LCD driver does not need extra cascaded drivers. n Product Number ST7032 supports various function for customer. Please specify correct product number for application: For example, “ST7032–0D” the first part is illustrated below and the second part is the identification code of the built-in character generation ROM. Please refer to the appendix for the character generation ROM code information. ST7032 6800-4bit / 8bit, 4-Line interface (without IIC interface) ST7032i IIC interface Sitronix Technology Corp. reserves the right to change the contents in this document without prior notice. |
