ATA5790N is a smart Passive Entry/Passive Start (PEPS) device that includes an embedded ultra-low-power AVR 8-bit microcontroller, a three-dimensional LF receiver module and an LF immobilizer interface in a single QFN38 package. The device has an integrated AES-128 cryptography hardware engine, which is accessible via both the immobilizer and the PEPS unit. The immobilizer interface can run in contactless mode, allowing energy supply and data transmission via the LF link. The ATA5790N is designed for automotive applications that require both immobilization and Passive Entry/Passive Start functions in one single key. It conforms to requirements of extremely low power consumption and provides all the necessary circuitry for the entire application.
