V6118
2, 4 and 8 Mutiplex LCD Driver
Description
The V6118 is a universal low multiplex LCD driver. The
version V6118 2 drives two ways multiplex (two
blackplanes) LCD, the version V6118 4, four way
multiplex LCD , and the V6118 8, eight way multiplex
LCD. The display refresh is handled on chip via a 40 x 8
bit RAM which holds the LCD content driven by the driver.
LCD pixels (or segments) are addressed on a one to one
basis with the 40 x 8 bit RAM (a set bit corresponds to an
activated LCD pixel). The V6118 has very low dynamic
current consumption , 150 µA max., making it particularly
attractive for portable and battery powered applications.
The wide operating range on both the logic (VDD) and the
LCD (VLCD) supply voltages offers much application
flexibility. The LCD bias generation is internal. The voltage
bias levels can also be provided externally for applications
having large pixels sizes. The V6118 can be used as a
column only driver for cascading in large display
applications. In the column only mode, 40 column outputs
are available to address the display. A BLANK function is
provided to blank the LCD, useful at power up to hold the
display blank until the microprocessor has updated the
display RAM.
