ICs for Car Access
Applications
Atmel® has about 30 years of design expertise in
automotive products. The company launched the first
dedicated transmitter for remote keyless entry (RKE)
applications in 1997. For car access applications, Atmel
provides a wide range of innovative ICs. Customers
can create their own designs using the low-power
Atmel T575xC/ATA575xC radio transmitter IC family,
a dedicated Atmel ATA581xC/2xC transceiver family,
an Atmel ATA572xC/ATA574xC receiver IC family,
and the Atmel AVR® microcontroller-based ATA577xC
RF transmitter family. The Atmel car access portfolio
includes all devices needed to design
a complete solution.
Uni-directional RF link for the
keyless entry function to open or
lock car doors. The immobilizer
system is built with a bi-directional
LF link operating with the AUT64
crypto algorithm.
Bi-directional RF link for RKE
functions as well as for the
extremely secure duplex RF link
in a Passive Entry Go (PEG)
system. The LF link is used
for the wake-up channel in a
PEG system as well as for the
immobilizer function to start the
RF communication.
