MODEL NO: DV-16235-2-S2FTLY
1.SCOPE
The DV-16235-2-S2FTLY, dot-matrix LCD unit of a 5 x 7- dot 16-character 2-line dot-matrix LCD panle, LCD driver, controller LSI and yellow green backlight LED fabricated on a single PCB. Incorporating mask ROM-based character generator and display data RAM in the controller LSI, the unit can efficiently display the desired characters under microprocessor control.
2.PRODUCT SPECIFICATIONS
2.1 General
•The LCD of the unit is STN (Super Twisted Nematic) gray Transflective type.
•Low power consumption with the dot-matrix LCD panel and CMOS LSI. Built-in backlight LED with high luminance and stable radiation.
•Thin, lightweight design permits easy installation in a variety of equipment.
•Allowing for being connected at general-purpose CMOS signal level, the unit can be easily interfaced to a microprocessor with common 4-bit and 8-bit parallel inputs and outputs.
•Multiplexing driving : 1/16duty, 1/4bias, 12 o’clock
•Built-in character generator ROM and RAM, and display data RAM: Character generator ROM
225 different 5 x 7 dot-matrix character patterns (Alphanumeric and symbols)
Character generator RAM
8 different user programmed 5 x 7 dot-matrix patterns Display data RAM
80 x 8 bits
•Numerous instructions
Display clear, Cursor home, Display ON/OFF, Cursor ON/OFF, Blink character, Cursor shift, Display shift
•The unit operates from a single 5V power supply
