| General 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 + 1 row of icons) or 65 rows x 118 columns (8 rows of characters + 1 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 120uA with no external component except the capacitor connected to VLCD. 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 VLCD decreases and the commutation frequencies of row and column drivers are also decreased. These three effects of partial display mode reduce drastically current consumption.
This circuit is also available as a standard module.
