Fake AT28HC256E-12SI? + MAX EPM7128SLC84-15

<< < (3/3)

NivagSwerdna:
I reordered my AT28HC256 from Farnell and my  AT28HC256F-90SU arrived today.

4x the price of the fakes...

Put it in the programmer... worked first time.

And it even fits the footprint on my PCB

Lessons learnt!

PS
I think I have a couple more fakes (6502s?) still in my collection but my MAX7128SLC84s and AT28HC256E-12SI are history)

NivagSwerdna:
I recently received some...



these seem to be TOO wide?  More fakes?

wraper:
Package looks like original

NivagSwerdna:
Using my chiptester... they don't seem to work... so I'm 99% sure they are fake
I have changed my mind... they are mostly OK... I did have one dud but the rest seem to pass the tests OK.
So I'm paranoid about Chinese supplied chips now... oh dear.
