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 120µA with no external component

except the capacitor connected to V_LCD. One important

feature on EM6125 is the partial display mode, which

enables important current consumption reduction. With

this function selected, only 17 rows remain active,

needed V_LCDdecreases and the commutation

frequencies of row and column drivers are also

decreased. These three effects of partial display mode

reduce drastically current consumption.
