Pin Difference on SX28 Dip and SSOP

SailerMan

I spent a whole day fabricating a board and soldering SMT componets, trouble shooting like crazy only to finally figure out that the SSOP and DIP have different PIN outs.

I was using page 13 of the SX Key Manual for Pin outs.

If anyone else is thinking that the Pin Outs are the same for the SX28 DIP and SSOP, think again.

I Think I might have destroyed my only two chips... [noparse]:([/noparse] Back to the drawing board.

Chris,

The SX Key Manual, look at page 13. I know that the picture is a DIP.

Do you think I destroyed my SX28 SSOP Chips?

·· It’s hard to say…But the SX-Key Manual refers to the DIP since that’s what comes with the SX Tech Tool Kits.· Take care.

Guenther's manual provides images of both with proper pinouts. Also the SX18 [noparse][[/noparse]no longer available] and the SX20.

Any assumptions that pinouts on packaging changes are the same will likely give you similar results.
The manufacturer's packaging specifications are really the only thing one should look at as differences can be quite subtle.

Yeah, my first time going from Dip to SSOP , I assumed the Pin outs were the same.. I won't make that mistake again.
