AR6001XL Technology Overview
Atheros ROCm™ Platform
Radio-On-Chip for Mobile (ROCm) Products
Introducing the Atheros ROCm platform of high-performance wireless solutions for mobile and embedded devices. The Atheros ROCm platform gives customers unsurpassed ability to:
  • Build the most power efficient devices
  • Design for smallest form factor applications
  • Achieve the most cost effective designs
    • Greater integration of functionality
    • Low-cost chip solution
  • Deliver Atheros-class performance in a wide array of mobile devices

AR6001XL Technology Overview
The AR6001XL allows direct connection to cellular baseband and application processors via SDIO, SPI, and memory-mapped parallel interfaces. Its on-board processing and storage capabilities allow it to be integrated with the host platform with minimal development upfront and minimal loading during runtime. With its high degree of on-chip integration, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Sophisticated system-level features include fast sleep/wake context switching for energy-efficient VoIP, adaptive radio biasing for low-power operation, and spur cancellation and radio co-existence features for cellular/Bluetooth/802.11 interference mitigation. The AR6001XL is designed from the ground up to be a robust, space and energy-efficient 802.11 solution to bring true broadband access capability to a range of mobile devices.

AR6001XL Chip Features
  • SDIO 1.1, SPI, UART, local bus parallel memory-mapped interfaces
  • Integrated RISC processor
  • External serial and parallel memory interfaces
  • Integrated MAC/baseband processor and radio
  • On-chip low-dropout linear regulator
  • Fractional-N synthesizer for radio agility and external reference frequency scaling
  • WEP, TKIP, and AES engines for line-speed encryption support
  • Advanced Quality of Service
  • Digital audio I2S output for wireless speaker support
  • Embedded low power FLASH

Solution Features
  • Leading Edge APSD support for energy-efficient VoIP (sleep between voice packets)
  • Fast channel scanning and changing for handset-assisted handover
