1.8V IO on NHD-2.4-240320CF-CTXI-F
« on: June 18, 2017, 01:21:51 PM »
Hello,

I want to interface the NHD-2.4-240320CF-CTXI-F with an 1.8V system. The datasheet (http://www.newhavendisplay.com/specs/NHD-2.4-240320CF-CTXI-F.pdf) mentions that IOVDD can be 1.8V, but the logic IO parameters Vih, Vil, Voh and Vol all are specified in terms of VDD (which is 3.3V). Is this a typo in the datasheet (intuitively, I would expect IOVDD to set the IO logic levels, instead of VDD) or can the display in fact only interface with 3.3V logic?

Thank you!
