The AT24CS64-MAHM-T is an EEPROM (electrically erasable programmable read-only memory) IC manufactured by Microchip Technology. This specific model is designed to operate with a Serial-3Wire interface and has a storage capacity of 64Kbits, equivalent to 8Kbytes by 8 bits. It can be powered by either 2.5V, 3.3V, or 5V power supplies. The IC is packaged in an 8-pin UDFN EP (ultra-thin dual flat no-leads exposed pad) format and is provided on a tape and reel for convenient automated manufacturing processes.
