Hi, A colleague of mine is having some difficulty with the Xicor X1227 part; as if it wasn't enough that we had problems with one of their real time clocks before. He states that the following issues occur: 1. 32kHz oscillator does not always start when 3v battery connected; it seems to need a 5v 'kick'. 2. Once started the 32kHz sometimes seems to stop for no obvious reason. Anyone else seen this part exhibiting this behaviour/offer any help?
