ATA5795 is a smart Remote Keyless Entry (RKE) device that includes an embedded
ultra-low-power AVR 8-bit microcontroller, a fractional-N RF transmitter and an LF
immobilizer interface in a single QFN32 package.
Furthermore, the device has an integrated AES-128 cryptography hardware engine,
which is accessible by both the immobilizer and the RKE unit. The immobilizer interface
can run in contactless mode, allowing energy supply and data transmission via
the LF link.
The ATA5795 is designed for automotive applications that necessitate both immobilization
and Remote Keyless Entry functions in one single key. It conforms to
requirements of extremely low power consumption and provides all the necessary circuitry
for the entire application.
