Our highly integrated ICs for car access and immobilizer applications combine

secure operation, convenience, and flexibility. The result is a portfolio of solutions

that are ideal for today’s advanced, feature-rich key designs.

Keyless entry/go family

Our market-leading chipsets for keyless entry/go deliver the ultimate in security and convenience, unlocking

the car automatically without any direct action by the key holder. Equipped with embedded low-power

processors, these cost-effective solutions enable a range of convenient features, including push-to-start.

They offer excellent LF sensitivity, sophisticated wake-up detection, ultra-low power consumption and

integrate 3D LF and RISC controller ICs.

Immobilizer and remote keyless entry family

We offer a range of devices, from standalone immobilizer transponders to fully integrated immobilizer

and remote keyless entry ICs, so you can choose exactly the right performance and functionality for your

application. Our remote keyless entry solutions include options with an integrated UHF transmitter and

transponder coil, and our basestation solutions simplify the design of immobilizer systems.

RF devices

To complement our keyless entry portfolio, we offer a full range of sophisticated RF devices for

communication in the ISM band, up to 1 GHz. We support cutting-edge designs for car access, with

extensive system know-how and a range of solutions – from a transmitter based on a fractional-N PLL to

transceiver and receiver solutions that integrate a variable bandwidth filter and a low-power polling timer.

Connectivity with the key of the future

Our latest keyless entry/go ICs offer innovative connectivity, employing an ISO14443 interface compatible

with Near Field Communication (NFC) devices. They make it possible for an NFC enabled mobile phone to

query vehicle status via the car key, and enable remote configuration of the car.
