atmel’s innovative single-wire devices provide the lowest pin count non-volatile memory solution available on the market. only two pins are needed to access these devices: si/o and gnd. the si/o signal is a combination data and power line, providing power to the device with a parasitic power scheme during the high time of the protocol sequence. the devices have ultra-high write endurance capabilities, allowing for greater than 1,000,000 write cycles to each and every memory location to meet the needs of today’s high write endurance applications. the single-wire family of products makes an ideal solution to implement a simple product identification with a plug-and-play, 64-bit, unique serial number included in every device. having esd tolerance to iec 61000-4-2, this si/o line can be directly accessed from outside the application. application examples include analog sensor calibration and storage data, ink and toner print cartridge identification, and management of after-market consumables.
