EM6124 Fact Sheet - EM Microelectronic

25 to 8 MUX LCD Controller and Driver
High Uniformity of Contrast and no external components
The EM6124 is an ultra-low power bit map controller and
driver for full dot matrix monochrome STN LCD displays. The
driving capability is 25 rows x 96 columns to 8 rows x 113
columns addressed by 3-wire interface. VLCD is internally
generated until 7V without external components.
