Microchip announces the industry’s lowest-power Passive Entry/Passive Start (PEPS) solution: The ATA5700 and ATA5702

Microchip announces the industry’s lowest-power Passive Entry/Passive Start (PEPS) solution: The ATA5700 and ATA5702 are primarily intended for use in battery powered applications such as smart keys (i.e. PEPS) and complementary car access via mobile devices, smartphones and wearables where the power consumption is one of the key requirements. 

Key benefits of the new devices include ultra-low power consumption, outstanding key localization accuracy and unique built-in counter relay (“man-in-the-middle”) attack protection measures. Car theft based on relay attacks of vehicles equipped with a PEPS system is becoming one of the top security concerns of automakers. The two new devices have a unique built-in Low Frequency (LF) vector calculation unit that allows customers to implement effective relay attack countermeasures at no additional cost.

The new devices also feature excellent low frequency sensitivity, enabling convenience features such as customized welcome-lighting upon approaching the vehicle or automatic “walk-away locking” of the vehicle – in a range up to 10 meters. The power consumption for this “always on feature” is industry leading, tripling the battery lifetime in the highest sensitivity mode. The devices offer the highest key localization accuracy in the market which is critical to accurately distinguish whether a key fob is located inside or outside the vehicle and to comply with accuracy requirements of insurance companies.
