Car Access

All the building blocks for typical RKE and access control systems for base and the mobile stations are fully integrated into Atmel key component devices.

For example, highly integrated Atmel receivers handle power-down, clock delivery, reset, low battery indicator, receive/transmit and polling operations, offloading the on the main microcontroller. Our smart RKE devices include an embedded low-power AVR 8-bit microcontroller, fractional-N RF transmitter and LF immobilizer interface in a single QFN32 package with an AES-128 cryptography hardware engine, accessible by both the immobilizer and the RKE unit.
