Car Access Reference System (CARS) Kit

Part Number: ATAK51004-V2

Summary:

ATAK51004-V2 provides a complete system showing an all Microchip® solution for Remote Keyless Entry (RKE), Passive Entry Passive Start (PEPS), and Immobilizer (IMM) applications. This system uses AES-128 encryption to protect the realistic multi-channel RF and LF communication protocols and supports 1-way RF communication for PEPS.

Two different learn modes (RF & LF)

Summary

ATAK51004-V2 provides a complete system showing an all Microchip® solution for Remote Keyless Entry (RKE), Passive Entry Passive Start (PEPS), and Immobilizer (IMM) applications. This system uses AES-128 encryption to protect the realistic multi-channel RF and LF communication protocols and supports 1-way RF communication for PEPS.

Two different learn modes (RF & LF) have been implemented to demonstrate pairing of a key fob to a vehicle. The status of the system is displayed on both the hardware LEDs and a comprehensive PC GUI. Combined with Microchip’s advanced devices, the multi-channel RF messaging provides exceptional performance even in the presence of interference. The system provides the basic hardware needed for the vehicle side, which includes the ATA5291, integrated immobilizer Basestation and 4-channel (expandable to 8) PEPS coil driver, as well as, ATA5782 RF RX along with a microcontroller. The key fob includes the ATA5702, which incorporates the 3-D Immobilizer and the 3-D LF wake up for PEPS with 1-way RF transmitter into a single IC device. Through this tool, Microchip has made it very easy to implement a complete car access and security system using Microchip high-performance devices.

This kit is supported by all standard AVR® development tools such as Atmel Studio 7, Atmel-ICE, JTAGICE3, etc.

Not available for purchase through microchipDIRECT®, please contact your local Microchip Sales Representative instead.
