SERIAL EEPROM

This document was created with FrameMaker 404SERIAL EEPROMSerial EEPROM Cross Reference GuideThe purpose of this document is to provide a quick wayto determine the closest Microchip equivalent to SerialEEPROMs produced by other manufacturers. Thecross reference section is broken down by manufacturerand lists all parts from that manufacturer, and thecomparable Microchip part number. There is also a listingof manufacturer’s part numbering schemes toassist in determining the specifications of a particularpart.There are subtle differences from manufacturer tomanufacturer and device to device, so Microchip recommendsconsulting the respective manufacturer’sdata book for specific details.Microchip provides a wide selection of Serial EEPROMdevices, both from a density and a packaging standpoint,as well as several different protocols. If you areinterested in a part that is not listed in this book, pleasecontact your local distributor or sales representative forassistance.The manufacturers † included in this document are asfollows:AKMAtmelCatalystExelISSIMicrochipMitsubishiNational SemiconductorOkiPhilipsSamsungSGS-ThomsonSiemensXicorFIGURE 1: MICROCHIP SERIAL EEPROM PART NUMBER GUIDEXX XX XX XX X / XXPackageProcess TemperatureOptionsLPSWSLSMSNSOSSSTTSVSBlankIEXTMemory 010204081632651172829206465666Voltage RangeCLCAAPart Number Designator 2425598593===============Plastic Leaded Chip CarrierPlastic Dual In-Line PackageDie in Waffle PackDie in Wafer Form14-Lead Small Outline—15 mil8-Lead Small Outline—208 mil8-Lead Small Outline—150 milSmall Outline—300 milShrink Small Outline Package—209milThin Shrink Samm Outline PackageThin Small Outline—8mm x 20mmVery Small Outline—8mm x 13.4mm0°C to +70°C-40°C to +85°C-40°C to +125°C= Rotated pinout (93LCXX devices)Tape and Reel1K2K4K8K16K32K64K1K1K2K4K256 Bit1K2K4K========128 x 8256 x 8512 x 81K x 82K x 84K x 88K x 8128K x 8 or 64 x 16128 x 8256 x 8512 x 816 x 1664 x 16/128 x 8256 x 8/128 x 16512 x 8/256 x 165.0V operation2.5V or 2.0V operation1.8 V operationI 2 CSPI4-wire2-wireMicrowire ®† The above trademarks are property of their respective companies.© 1996 Microchip Technology Inc.
