• Supports Frequency Ranges in the 6.2 GHz to 7.8 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 at 246 Kbps
• Fast SPI Interface (20 Mbps) for Data Communication and Configuration between the ATA5350 and Host Microcontroller
• Time-of-Flight Distance Measurement with ±15 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
• Low RX and TX Peak Power allows Coin Cell Battery Applications with an External DC-DC Converter

The ATA5350 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 ATA5350 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 7.8GHz

  • Ensure ETSI and FCC regulation compliance with programmable transmitted peak output power up to a typical value of 9 dBm

The ATA5350 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-Flight (ToF) measurement.  The ATA5350 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.
