Standard, low-cost EEPROM memory smartcard with 1K bytes of available storage, with an irreversible write protection feature and a 2-byte programmable security code.

Developed by Philips in the early 1980s, this simple two-wire bus with a software-defined protocol has evolved to become the de facto worldwide standard for system control, finding its way into everything from temperature sensors and voltage level translators to EEPROMs, general-purpose I/O, A/D and D/A converters, CODECs, and microprocessors of all kinds.

For smart card and secure embedded applications, Atmel offers the industry's largest range of devices based on our proven EEPROM and Flash technologies.
