GENERAL DESCRIPTION
The HCS412 combines patented KEELOQ code hopping technology with bi-
directional transponder challenge-and-response security into a single chip
solution for logical and physical access control.
When used as a code hopping encoder, the HCS412 is ideally suited to keyless
entry systems; vehicle and garage door access in particular. The same HCS412
can also be used as a secure bi-directional transponder for contactless token
verification. These capabilities make the HCS412 ideal for combined secure
access control and identification applications, dramatically reducing the cost
of hybrid transmitter/transponder solutions.
