8-, 16- and 32-bit Microcontrollers/Microprocessors TWR-WIFI-AR4100 Tower System 802.11n Wi-Fi module Overview The TWR-WIFI-AR4100 peripheral module provides an ultra low-power wireless solution with 802.11n Wi-Fi connectivity using the Freescale Tower System. This fully FCC- and CE-certified Qualcomm Atheros system-in-package module comes with MQX software and enables you to quickly go from the lab to production with the same Wi-Fi hardware module. The on-board Qualcomm Atheros silicon features easy-to-use wireless connectivity for the entire home, and pre-certification will save you time and money in getting your product to market. This peripheral module is designed to be combined and used with other microcontroller and peripheral modules in the Tower System.Features The Freescale Tower System Ultra low-power AR4100 802.11n Controller Module Primary Elevator Wi-Fi system-in-package solution from Tower MCU/MPU board Common serial and Qualcomm Atheros expansion bus signals Works stand-alone or in Tower System Two 2x80 connectors Low energy and low system resource on backside for easy Features integrated signal access and requirements debugging interface for side-mounting board easy programming and (LCD module) Integrated RF front end, RF shield, 32 kHz run control via standard USB cable Power regulation sleep clock and system clock circuitry Standardized signal Best-in-class Rx sensitivity for superior Secondary Elevator assignments throughput rate-over-range performance Additional and Mounting holes secondary serial and Integrated high-power, high-efficiency expansion bus signals Board Connectors power amplifier Standardized signal assignments Four card-edge Low-density parity check (LDPC) encoding connectors Mounting holes and expansion connectors for improved uplink robustness over range Uses PCI Express for side-mounting connectors peripheral boards (x16, 90 mm/ Space time code blocking (STBC) for 3.5 long, 164 pins) Size Peripheral Module improved downlink robustness over range Examples include serial interface module, Tower is approx. 3.5 H x 3.5 W W i-Fi protected setup (WPS) 2.0 x 3.5 D when fully assembled memory expansion module and Wi-Fi FCC and W i-Fi certified Compatible with the Tower System, including MQX-based driver support SPI interface to Tower MCU modules On-board SPI flash for enabling minimal impact to MCU resources Tower Geeks Online Community Access to expansion GPIO and debug TowerGeeks.org is an online design signals for advanced development engineer community that allows members to interact, develop designs and share ideas.
