General Description
EM6127 is a controller and driver for graphic or character
monochrome TN – Twisted Nematic, STN – Super-Twisted
Nematic and Filtered STN LCD displays. Several EM6127 integrated functions save system power needs. The enhanced
EM6127 driver displays different character or bitmap formats. Various effects are available such as scrolling, reverse,
blinking and more are available. In addition, the controller is able to display ROM-defined or RAM custom-made
messages. EM6127 can start in user-defined modes and
The EM6127 is an extremely low power LCD controller and
driver product. The typical current consumption is typically
20 µA in MUX 32 configuration with internally generated
VLCD and external capacitors.
The one character line, active addressing mode is an important feature of the EM6127. It provides significant improvement in current consumption. The typical current consumption in this mode is only 5 µA.
The 5x7 character format can be zoomed 2 or 3 times
(10x14 and 15x21), such that a large date can be displayed,
for example.
