Hi PaulThanks for the reply, sorry don't have access to a oscilloscope, but do have a DVM, having taken a few measurement, the voltage reading don't go over 3.2v on 3 of the pins and 0 on the fourth which I take it is ground, so I think the arduino would be ok.
HiSorry for the delay in responding, I could not magnify it enough to read it last night, anyway this is what is on the top of the chip :ATH55202CM YAB20PAI did a lot of searching on all parts but was unable to get any info about the chip.Potman
Looking at the Data Sheet its says that, that if pin 7 is not connected to vcc then it is grounded, anf the memory is read write, but if connected to vcc it is write protected, if I linked vcc and wp (pin 7), this would write protect the memory, so do you think this will stop any time being removed from the chip ?ThanksDarren
