Using a C932. In sleep mode we ought to be at about 2uA - instead we sit at 25uA. This is with the part with I/O lines in the air, external xtal, VCC and ground. We have done everything in the book, but still this high power drain, making the chip useless in a battery application. Anybody out there see anything close to book power in sleep mode? Thanks!

Thanks Erik We have actually gone so far as to run the 932 in a socket, to be sure our PCB was not the cause of the problem. Where we should be burning 2uA ro 4uA we get consistant 24uA Did try running on the internal clock - which the book suggests would actually be a higher current - no difference. What is the lowest power down current you have seen? Thanks, R
I have never powerdowned (sorry) a LPC932, just repeated some info someone gave me sometime. Erik
