  • FreeRTOS.org

  • Micrium µC/OS-II with µC/Probe embedded system monitoring

  • Express Logic ThreadX

  • CMX Systems CMX-RTX

  • Keil RTX

  • IAR PowerPac

  • SEGGER embOS

  • Quadros RTXC

  • MicroDigital’s SMX

  • RoweBot’s Unison ultra-tiny embedded Linux- and POSIX-compatible RTOS

  • SCIOPTA’s real-time operating system for safety-critical applications

Aggregation manager connectivity

TI’s AM reference designs include two Continua WAN interfaces (Ethernet and Wi-Fi), a low-power LAN interface (ZigBee) and four PAN interfaces (USB, Bluetooth, Bluetooth low energy and ANT).

Wi-Fi TI’s WiLink6.0 (WL127x) solution is a highly integrated, 65-nm offering that integrates WLAN, Bluetooth and FM cores onto a true single chip. The WiLink 6.0 solution supports the latest standards, including 802.11 a/b/g/n and various Bluetooth technology generations. It is designed for the mobile devices like smartphones and other battery-operated devices that require robust connectivity at low power conservation.

The WiLink 6.0 is accompanied by an external off-the-shelf switched-mode power supply (SMPS) and front-end module. The front-end module contains a PA, a balun and a three-way radio-frequency switch.

TI’s WiLink 6.0 solution is a triple-radio design that employs special techniques to address radio coexistence challenges. Special care is taken in the integration of WLAN and Bluetooth because both operate on the same frequency band. A proprietary set of algorithms addresses this issue to allow the use of a single antenna shared between WLAN and Bluetooth for the 2.4-GHz band.

Overall solution size is sometimes a key factor in mobile devices. Because of the small footprint of the WiLink 6.0 solution, core device, the resulting total size is less than 80 mm.
