HCS412 Overview
The HCS412 bines patented K EELOQ® code hopping tech nology with bi-di rectional 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; vehi cle an d garage do or access i n particular.
