thanks Festy, good comments!

Previously ive only heard that either No Bin Logo or 100ns part (70ns is all that is sold according to datasheets) indicate a fake. Your comments defiantly make sense! That was one thing i thought once i saw the CR battery, dont know how that's ment to last 10yrs!!

EDIT: the one in the photo i bought 6 months ago, it lasted only 6months obviously, the battery is flat only reads about 200mv. It would write then verify then after a few seconds would be corrupt again.

Other signs are that the cover shouldn't just pop off, and I don't think the dimple above pin 1 should be there.

well im looking forward to yours fest! Maybe the only reliable ones!

a search on ebay for DS1245Y indicates 100% fake atm. Looking elsewhere to find some atm.

The ones I supply with boards are genuine, industrial rated and 70nS (there are other genuine speeds too) but sadly they come at a cost and have to buy them in quantity The DSfesty should be cheaper

Another way to spot fakes - the dodgy serial number
http://www.ebay.com.au/itm/1PCS-DS1245Y ... 4aaea2bc1d
date code 1010, but same serial as The1's.

and in that ones case it's $8 lol

just for the record i got an email back from maxim and there official disty to the public is mouser.

Bit of a delay with some parts being out of stock.
I'll have a couple ready for testing in 3 weeks, more if the back ordered parts turn up by then.

The boards arrived today - just need to pick up some shorter pcb pins because the machine pins I was going to use make it too tall to fit in the 808's case without mods. My 'test bench' ecu is running off this module now.

That looks good. Any idea of cost yet?
