It's my impression that the difference between the CDP1802ACE and the> CDP1802AE is just that the latter is rated to 6.4 MHz at 10 V and the
> former is spec-limited to 6.5 V; and that the difference between the
> AE and the AEX is just additional burn-in for the AEX.
Ok, clearly I'm off on my own here. Let's try a different question:
Is anyone using -AE or -AEX chips in Membership Cards or Elf builds?
