1. Description
The Atmel® CryptoRF® family integrates a 13.56MHz RF interface with Atmel CryptoMemory® security features. This
product line is ideal for RF tags and contactless smart cards that can benefit from advanced security and cryptographic
features. The device is optimized as a contactless secure memory for secure data storage without the requirement of an
internal microprocessor.
For communications, the RF interface utilizes the ISO/IEC 14443-2 and -3 Type B bit timing and signal modulation
schemes, and the ISO/IEC 14443-3 Slot-MARKER Anticollision Protocol. Data is exchanged half duplex at a 106-kbit per
second rate, with a two byte CRC_B providing error detection capability. The RF interface powers the other circuits, no
battery is required. Full compliance with the ISO/IEC 14443 -2 and 14443 -3 standards provides both a proven RF
communication interface and a robust anticollision protocol.
The five products in the CryptoRF family contain 4 to 64 kilobits of user memory plus two kilobits of configuration
memory. The two kilobits of configuration memory contains:
Read/Write password sets
Four crypto key sets
Security access registers for each user zone
Password/Key registers for each zone
The CryptoRF command set is optimized for a multi-card RF communications environment. A programmable AFI register
allows this IC to be used in numerous applications in the same geographic area with seamless discrimination of cards
assigned to a particular application during the anticollision process.

6. Anticollision Command Definitions
Commands in this section are arranged in order by the hexadecimal code in the command byte.
6.1 REQB/WUPB Polling Commands [$05]
The REQB/WUPB command is used to search for PICCs in the RF field. The command and response are ISO/IEC
14443-3:2001 compliant.

Operation
The “Request B” (REQB) and “Wake-Up B” (WUPB) commands are used to probe the RF field for Type B PICCs as the
first step in the anticollision process. The response to an REQB or WUPB command is the “Answer to Request B”
(ATQB). PICCs in the Active State are not permitted to answer this command.
