Description EM6110 is a bit map low multiplex controller and driver for full dot matrix B/W TN and STN LCD displays. The driving capability is 8 rows x 32 columns or 4, 3, 2, 1 rows x 40 columns. The display refresh is implemented internally. The display data are entered by a 3-wire or I2C interface. The display data are stored in 2 selectable 8x40 RAM (Double RAM mode). The RAM data correspond directly to the LCD pixels (segments): a set bit in the RAM results in an activated LCD pixel. EM6110 can be easily cascaded and it can be used in large display applications. The very low current consumption, the...
