Description
The EM6125 is a bit map controller and driver for full dot
matrix monochrome STN LCD displays. The driving
capability is 81 rows x 102 columns (10 rows of
characters + one row of icons) or 65 rows x 118 columns
(8 rows of characters + one row of icons). There is a one
to one relation between LCD pixels and bits of the
Display Data RAM.
The EM6125 is extremely low power consumption LCD
controller and driver product. The typical current
consumption is about 120
μ

. One important
feature on EM6125 is the partial display mode, which
enables important current consumption reduction. With
