1. General description
EM65568 is one of the industry's most advanced wide-screen STN-LCD drivers for 4096-color display. The industry's first
sub-screen display function makes it possible to display different images and data in a sub-screen inside the main LCD screen.
It also has a built-in display RAM, a power supply circuit for LCD drive, and an LCD controller circuit, therefore contributing
to compact system design. Its partial display function realizes low power consumption.
*Partial display function: A function that utilizes only part of the screen, thus reducing power consumption.
2. Feature
4096-color display
LCD outputs: Segment 128RGB(384 outputs); Common 130 outputs
Display RAM capacity: 128x130x12=199680 bits
Built-in display RAM and power supply circuit
Partial display functions
Switchable display in black and white mode
Bus connection with 80-family/68-family MPU/ELAN MPU
Logic power supply voltage: 2.2 to 3.3 V
LCD driving voltage: 5.0 to 18 V
Booster: 2 to 6 times
Write system cycle: 200 ns
