ST7070
Dot Matrix LCD Controller/Driver
16-common x 80-segment liquid crystal display driver Programmable duty cycles -- 1/8 for one line of 5 x 8 dots with cursor -- 1/16 for two lines of 5 x 8 dots & cursor Wide range of instruction functions: Display clear, cursor home, display on/off, cursor on/off, cursor shift, display shift Automatic reset circuit that initializes the controller/driver after power on Internal oscillator with external resistors Low power consumption Bare Chip available (ST7070-XX-B)
Description
The ST7070 dot-matrix liquid crystal display controller and driver LSI displays alphanumeric, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor. With high speed serial interface(3-line SPI , 4-line SPI), the external MCU can control ST7070 directly. Since all the functions such as display RAM, character generator, and liquid crystal driver, required for driving a dot-matrix liquid crystal display are internally provided on one chip……
