Mustafa, The typical standby current of the at45db041b (used on the mica2 and not too recent micaz motes) is 2uA. This is what the chip draws if there is no read/write/erase operation in progress. You cannot go any lower than that. The data sheet is at http://www.atmel.com/dyn/resources/prod_documents/doc3443.pdf
The newer micazs and the iris motes are equipped with a at45db041d, where the standby current is slightly higher, typically 25uA. You can switch this version of the flash chip to deep powerdown mode, where it typically draws 5uA. If you consider 20uA a "considerable amount of ampere", you may want to check page 24 of the datasheet where it is explained how to enter deep power-down mode. The data sheet is at http://www.atmel.com/dyn/resources/prod_documents/doc3595.pdf Janos -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mustafa gozkun Sent: Wednesday, February 13, 2008 4:14 AM To: [email protected] Subject: [Tinyos-help] disabling external flash Hi all, Isnt there anybody to answer how to disable external flash? I will gain considerable amount of ampere by doing so. I would be happy to hear from someone. thanks in advance ________________________________________________________________________ ____________ Never miss a thing.
