Extended Temperature range LCD

[SounDuke]

I found a working ATM1602B in my scrap  SEE:  http://www.hebeiltd.com.cn/?p=LCM.alphanumeric.blue  but I don't know if I can use it. It has an extended temperature range and thereby requires a negative voltage, I've built a core module and 2 dinx4, and I would like to connect this LCD to the core. What do you think?

I took a quick look, but there is no mention of a negative voltage (it's not in the mini datasheet). Simply 5V supply.

It should work as the page says "Built-in controller HD44780 compatible". That one is supported by MIOS.

I'll give it a try,what scares me is that my display looks a little bit different from the one in the minidatasheet
