Is that possible to drive a 5V liquid crystal display with the 3.3V STM32L073 mcu?

Hi,

A customer is in the process of sending to manufacture a 5V, 15 segments and 8 planes, custom LCD. I wonder whether the STM32L073 mcu is going to be capable of driving such display. Put it in other words: whether 3.3V is going to be good enough for driving the segments and planes.

I want to use this mcu because its integrated LCD driver, however, I'm affraid it can't. I'm attaching the specs.

I'm just starting the hardware design, and I really don't want to use an external driver, like the ubiquitous HT16C22. 

 

Thank you!

The built-in LCD controller in STM32 can't drive more than 3.3V.

Hi,

I don't think this is possible. Think about a voltage level shifter solution.
