Qualcomm Atheros Inc. has released the AR4100P, an integrated 802.11n single-stream Wi-Fi system-in-package with integrated networking stack. The AR4100P is an enhanced version of the company's FCC-certified AR4100 that includes an integrated IPv4/IPv6 TCP/IP stack. Aimed at customers implementing machine-to-machine (M2M) communications in the smart home, building and appliances channels, the AR4100P provides system designers a more highly integrated solution, thereby lowering system costs and simplifying system design.
I spoke with Tim Colleran, Director of Marketing, Smart Home and Smart Building at Qualcomm Atheros, about the new release. He emphasized that in addition to offloading Wi-Fi and security from the microcontroller, the new SIP can also house the IP networking stack. This allows designers to use a smaller host microcontroller and lower system cost.
The new SIP is part of the company's SP137 development kit, which integrates Energy Micro's EFM32 Gecko low-energy Cortex-M3 microcontroller running the Micrium uC/OS-III™ operating system. This development kit supports deep sleep modes of only 2uA, enabling operation off of AA batteries. The kit also includes expansion capabilities for additional sensors and can be ported to other microcontrollers or operating systems as required. The design flow for the kit is centered on the Embedded Workbench® Integrated Development Environment from IAR Systems.
Qualcomm Atheros will demonstrate the AR4100P and AR4100 solutions in Qualcomm's exhibit (#2101) at the Embedded Systems Conference/DESIGN West, March 26-29 in San Jose, Calif.
Join our online Radio Show on Friday 11th July starting at 2:00pm Eastern, when EETimes editor of all things fun and interesting, Max Maxfield, and embedded systems expert, Jack Ganssle, will debate as to just what is, and is not, and embedded system.
