Atmel’s AT88RF020 low-cost 2-Kbit RF Transponder EEPROM Smart Card IC is fully compliant with the Type B requirements of ISO/IEC 14443. This chip is powered by the RF interface, so a battery is not needed. A tuning capacitor is included on-chip so only a single external coil antenna is required to operate the device. The AT88RF020 is compatible with any Type B RF Smart Card Reader.

Security

AT88RF020 has several security features. A 64-bit password protects the 224-byte user memory which cannot be read or written unless the correct password has been presented. Write Lock bits protect critical data from being over-written. Each Lock bit protects an 8-byte page, so once the Lock bit is set the data can never be changed. The AT88RF020 features a one-way transaction counter that allows tracking of individual device usage. The counter is set at the factory to zero and is incremented by a COUNT command that simultaneously writes the Signature field. The counter can never be reset or decremented. Atmel uniquely serializes each device with a 32-bit read-only serial number.

Memory Map

AT88RF020 contains 256 bytes of memory configured as shown below. The first three pages can always be read by the system. Page 3 is the password and can never be read. Pages 4 thru 31 are the user memory area that can only be accessed after password validation.
