GENERAL DESCRIPTION
The ST7093 dot-matrix liquid crystal display
controller can drive 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 4bit, 8 bit or 4 pin clock
synchronized serial bus interface. For 4 bit and 8 bit
bus interface both 68 series and 80 series type are
available. Since all the functions such as display RAM,
character generator, liquid crystal driver, oscillator and
voltage control functions required for driving a
dot-matrix liquid crystal display are internally provided
z 26 common x 80 segment liquid crystal display
driver
z 32 steps electronic volume control
z Wide range of instruction functions:
return home, display on/off, cursor on/off, display
character blink, double height, line shift, function
set, power and bias control
z Hardware reset pin available
z Internal oscillator or external clock
z Power save mode for low power consumption
z Bare Chip available
on one chip, a minimal system can be interfaced with
this controller/driver.
The ST7093 character generator ROM is
extended to generate 256 5 x 8 dot character fonts.
The low power supply (2.4V to 3.6V) of the ST7093 is
suitable for any portable battery-driven product
requiring low power dissipation.
The ST7093 LCD driver consists of 26 common
signal drivers and 80 segment signal drivers with COG
gold bump available.
