Serial EEPROMs

Cross-reference guide

www.st.com/eeprom

Introduction

How to use the cross-reference guide

This cross-reference guide is intended to help you find out the ST serial EEPROM

products most compatible with devices from other vendors.

It is very easy to use: simply choose the competitor part number, according to

memory size, and you’ll find the ST equivalent part number. In all cases, we

recommend you to check the parameters in the appropriate datasheet, to ensure that

the product meets the requirements of your application. Please note that this guide

is based on information published by other manufacturers at the time of publication.

Serial EEPROM complete cross-reference information is available at

www.st.com/eeprom or on ST Intranet. If you are interested in receiving more

information about these and other products, or if you have any technical enquiry,

please contact the ST sales office in your area, or send an e-mail to

apps.eeprom@st.com (for application support) or ask.memory@st.com (for general

enquiries).
