Keyless Entry

1. Description

ATA5795 is a smart Remote Keyless Entry (RKE) device that includes an embedded

ultra-low-power AVR 8-bit microcontroller, a fractional-N RF transmitter and an LF

immobilizer interface in a single QFN32 package.

ATA5795

Furthermore, the device has an integrated AES-128 cryptography hardware engine,

which is accessible by both the immobilizer and the RKE unit. The immobilizer inter-

face can run in contactless mode, allowing energy supply and data transmission via

the LF link.

Summary

Preliminary

The ATA5795 is designed for automotive applications that necessitate both immobili-

zation and Remote Keyless Entry functions in one single key. It conforms to

requirements of extremely low power consumption and provides all the necessary cir-

cuitry for the entire application.
