SOT23 package 24LC32A EEPROM

I noticed the 24LC32A EEPROM can be had in a SOT23-5 package. Probably a dumb question but I'd like reassurance before I manufacture a PCB. Would this work the same as a SOIC-8 package unit when communicating with the FV1? Assuming I don't need the additional functionality available in the SOIC-8 package. The SOT23 lacks the A0, A1, A2 pins. According to the datasheet:

"For the SOT-23 package, Chip Address Inputs are not available and are not connected."

and

"For the SOT-23 package, the address pins are not available. During device addressing, the A1, A2 and A0 Chip Selects bits should be set to ‘0’."

Shouldn't be any problem using those. The main difference with the SOIC-8 package (beside the size... :mrgreen: ) it's that the address is fixed to 0 and that's exactly what you need on the FV-1.

Thank you! Now to cram even more stuff onto my PCBs... ;)
