• Supports Frequency Ranges in the 6.2 GHz to 8.3 GHz Ultra-Wideband (UWB)
• Uses 3db™ Low-Power Secure Ranging Technology
• Compliant to UWB Regulations of ETSI (EN 302 065-3 V2.1.0) and FCC (Title 47, Part 15)
• UWB Data Communication up to 1 Mbps
• Fast SPI Interface (24 MHz) for Communication between the ATA8352 and a Host Microcontroller
• Single Distance Measurement with 4 cm Resolution
• Distance Measurement Method Is Secured against Multiple-Attack Scenarios, For Example, Cicada Attack, Early Detect/Late Commit, Preamble Injection
• Ideally suited as countermeasure to Passive Entry / Passive Start (PEPS) Relay Attack
• RX and TX Peak Power Allows Coin Cell Battery Applications with an External DC-DC Converter

The ATA5352 device is a low-power Ultra-Wide-Band (UWB) transceiver with integrated security layer for secure distance bounding, localization and point-to-point data communication. The ATA5352 device’s digital transmitting circuitry ensures maximum flexibility in the generation of UWB pulse signals.  The transmitter is able to:

  • Generate accurate pulse durations ranging from less than 1 ns to more than 10 ns with controlled envelope shape

  • Generate a carrier frequency between 6.2 GHz and 8.2 GHz

  • Ensure ETSI and FCC regulation compliance with programmable transmitted peak output power up to a typical value of 11 dBm

The ATA5352 Front-end (FE) receiver provides an excellent sensitivity to guarantee a superior link budget for the RF communication. The digital base band signal processing unit ensures a highly stable sub nanosecond Time-of-Arrival (ToA) estimation.  The ATA5352 includes a MAC layer for secure distance-bounding measurement and data communication for proximity-based access control. The layer can be configured to ensure different degrees of security while providing a sufficient number of distance measurements to be run in one secure access control session.
