HCS473
The HCS473 combines the patented KEELOQ® code hopping technology and bi-directional transponder challenge-and-response security into a single chip solution for logical and physical access control. High security learning mechanisms make this a turnkey solution when used with the KEELOQ® decoders. When the HCS473 is used as a code hopping encoder device, it is ideally suited to keyless entry systems. It is meant to be a cost-effective, yet secure solution to such systems. The HCS473 can also be used as a secure bi-directional transponder for verification of a token. The HCS473 has three sensitive transponder inputs that offers a omni-directional communication range beyond traditional transponder systems. This makes the HCS473 ideal for passive keyless entry, secure access control and identification applications. A single HCS473 can be used as an encoder for Remote Keyless Entry (RKE) and a transponder for immobilization in the same circuit and thereby dramatically reducing the cost of hybrid transmitter/transponder circuits.
