Description
The ST7066 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.
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, a minimal system can be interfaced with this controller/driver.

Features
● 5 x 8 and 5 x 11 dot matrix possible
● Low power operation support:
   -- 2.7 to 5.5V
● Wide range of LCD driver power
   -- 3.0 to 11V
● Correspond to high speed MPU bus interface
   -- 2 MHz (when VCC = 5V)
● 4-bit or 8-bit MPU interface enabled
● 80 x 8-bit display RAM (80 characters max.)
● 9,920-bit character generator ROM for a total of
   240 character fonts
   -- 208 character fonts (5 x 8 dot)
   -- 32 character fonts (5 x 11 dot)
● 64 x 8-bit character generator RAM
   -- 8 character fonts (5 x 8 dot)
   -- 4 character fonts (5 x 11 dot)
● 16-common x 40-segment liquid crystal display
   driver
● Programmable duty cycles
   -- 1/8 for one line of 5 x 8 dots with cursor
   -- 1/11 for one line of 5 x 11 dots & cursor
   -- 1/16 for two lines of 5 x 8 dots & cursor
