描述 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.
