SERIAL EEPROM
Serial EEPROM Cross Reference Guide
The purpose of this document is to provide a quick way to determine the closest Microchip equivalent to Serial EEPROMs produced by other manufacturers. The cross reference section is broken down by manufacturer and lists all parts from that manufacturer, and the comparable Microchip part number. There is also a listing of manufacturer’s partnumbering schemes to assist in determining the specifications of a particular part. There are subtle differences from manufacturer to manufacturer and device to device, so Microchip recommends consulting the respective manufacturer’s gadabout for specific details. Microchip provides a wide selection of Serial EEPROM devices, both from a density and a packaging standpoint, as well as several differentprotocols. If you are interested in a part that is not listed in this book, please refer to the Microchip data book, or contact your local distributor or sales representative for assistance. The manufacturers* included in this document are as follows: AKM Atmel Catalyst Exel ISSI Microchip Mitsubishi National Oki Philips Samsung SGS-Thomson Siemens Xicor
