We're looking at using an LK204-7T-1U-LV (low voltage) display in an embedded project. We'll be driving it over serial with an Atmel XMega AVR, with Vcc=3v3.

It's not clear to me what the "TTL" voltage level for this display is. Is the serial voltage threshold low enough for me to communicate directly from the AVR's uart pins (3v-ish, I'm guessing), without the need for a level shifter?

Thanks,

Hello duck,

Thank you for posting on the forum.

TTL levels for the LK204-7T-1U-LV is 0 - 3.3V.
You do not need level translator since you will be using same voltage levels.

Thank you,
