EM6126
81 and 65 MUX LCD Controller and Driver
High Uniformity of Contrast and no external components
Description
The EM6126 is an ultra-low power bit map controller and
driver for full dot matrix monochrome STN LCD displays. The
driving capability is 81 rows x 102 columns or 65 rows x
118 columns addressed by I²C or 3-wire interface. V_LCD is
internally generated up to 11V without external components.
