R Serial EEPROMS January 1999 Atmel's Serial EEPROMs Solutions for all your design needs Every Configuration of Serial EEPROMS Atmel entered the Serial-interface EEPROM market in 1992. Since then, Atmel has become a leading supplier of these small, low-power memory devices. Serial EEPROMs are in-system reprogrammable and are used to "remember" personal preference and set-up/configuration data in consumer, telecommunication, and automotive applications. Atmel manufactures every Serial-interface EEPROM in the market today. The Company offers the broadest selection of 2-wire, 3-wire, 4-wire, and SPI devices available. All of Atmel's Serial EEPROMs are in densities up to 1M, operate down to 1.8 volts and have one million erase/write cycles. Atmel offers the ideal Serial memory solution at competitive prices. So...if you are looking for Serial EEPROMs, think about Atmel--we have solutions for all your design needs. Benefits * Densities ranging from 1K-1M bits and options to cascade densities for up to 2M bits of memory * Pioneered 1.8-volt EEPROMs, which reduce power needs up to 80-percent--Ideal for portable or battery-operated systems * Standard one million erase/write cycles * Devices offered in commercial, industrial, and automotive temperature ranges * Choose from the industry's smallest footprints, including MSOP, TSSOP and LAP packages Atmel Corporation * 2325 Orchard Parkway * San Jose, CA 95131 TEL: (408) 441-0311 * FAX: (408) 487-2600 Atmel's Broad Serial EEPROM Family Part Number Density
