Car Access
Car access keys have evolved radically from the simple steel key to today's role as the human interface to the car. High security is a must for car access applications, and is also required by insurance companies worldwide.
Remote Keyless Entry (RKE) systems combined with immobilizers are standard in nearly all cars today. Passive Entry/Go (PEG) applications offer the ultimate convenience for car users, and are well-established in current luxury vehicles. As consumers demand additional convenience, these features are increasingly making their way into medium-class cars. To meet these demands, developers need cost-efficient electronic system solutions that support a high level of integration.
Atmel® introduced its first dedicated car access transmitter in 1997, and continues to recognize the importance of automotive security. We offer a wide range of car access devices that are ideal for developing complete system solutions with the highest levels of security and convenience, supporting remote keyless entry, immobilizer, passive entry/go or combi key applications.
