Car Access

Redefining Safety and Convenience

Remote keyless entry (RKE) systems with immobilizers are standard in nearly all cars today, while security is a must for car access applications, and is required by insurance companies worldwide. Passive entry/go (PEG) applications offer the ultimate convenience and are well established in today’s luxury vehicles. And, as consumers demand more convenience, they are increasingly making their way into medium-class cars.

To meet these rising demands, you need cost-efficient electronic system solutions that support many applications. Since its first dedicated car access transmitter in 1997, Atmel continues to offer a wide range of devices with the highest level of security and convenience and support RKE, immobilizer, PEG and or a combination of car access features.

Atmel's latest car access products all support the Advanced Encryption Standard-128 (AES-128), an open source cryptography standard that allows interoperability between different semiconductor vendors and true peer-reviewing for maximum security. In fact, Atmel is the industry's first electronics vendor to deliver an AES-128 open source immobilizer protocol stack.
