Microchip Technology Inc., the leading manufacturer of microcontroller, memory and analog semiconductors, has come up with the industry’s lowest-power Passive Entry/Passive Start (PEPS) solution. These two newly introduced devices, termed as ATA5700 and ATA5702, can operate in a long range of approximately 10 meters and carry ultra-low power consumption. Besides, these devices carry a battery life which is 3 times longer than other products in the market and all this while performing in the highest sensitivity mode.
A unique feature of these Microchip products is that these are equipped with an open-source, zero-cost license immobilizer protocol based on AES-128 that allows interoperability, thereby enabling a large number of customers to deploy second sourcing strategies. Such open source protocols are extremely beneficial for OEMs because unlike the private and secret protocols, these encourage a broad and continuous peer reviewing process by the whole industry which helps in improvement.
Apart from the aforementioned details, the products- ATA5702 and ATA5700 also carry elements like 3D immobilizer, 3D high sensitivity LF receivers, LF vector calculation, digital processing unit, 128 bit crypto engine, and a microcontroller. The only difference between these two devices is that the former is enhanced with an in-built RF transmitter fractional phase-locked loop (PLL) that provides protection against the jammers via a robust and immune ultra-high frequency (UHF) link.
Moving on, these devices are equipped with an in-built Low Frequency (LF) vector calculation unit which enables the customers to build countermeasures for effective relay attack (man-in-the-middle) without incurring an additional cost. The relay attacks of PEPS systems has become a major security concern for the automakers.
Mr. Matthias Kaestner, Vice President, Microchip’s Automotive business unit, stated, “The fast growing passive entry market is driven by an increased end consumer demand for convenience- hands-free entry, hands-free locking or even personalized welcome lighting. He further added, “As these devices become more and more prevalent, the need for secure solutions that can’t be hacked becomes vital, and Microchip provides what our customers need.”
The main intention behind introducing these devices is to use them in battery powered applications, like smart keys or other complementary car access via mobile devices such as smartphones and wearables, whereby power consumption is a noteworthy aspect. Through these products, car makers can avail the highest localization accuracy in the market. This would help them to efficiently determine if the keyfob is located inside or outside the vehicle. It will also assist in complying with the 5cm accuracy needs of insurance companies.
