> What's the difference between a 16F628 & 16F628A? - http://www.microchip.com/download/lit/migrat/40048a.pdf - the 16f628a is not even available for sampling yet, so I assume it is still unobtainium - the main difference is that one of my favourite features of the 16F628, the ER oscillator mode, has been removed.
