... The AT88RF04C contains 4 Kbits of user memory and 2 Kbits of configuration memory. The 2 Kbits of configuration memory contain four sets of read/write passwords, four crypto key sets, security access registers for each user zone, and 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 used in numerous applications in the same geographic area with seamless discrimination of cards assigned to a particular application during the anticollision process ...
