Subject to technical modifications! Universal embedded WLAN solution for OEM customers WiBear-SF - Industrial universal WLAN front end module (IEEE 802.11b/g) The lesswire industrial universal WiBear-SF- WLAN module is a reliable, automotive grade WLAN front end module. The module is developed for use in industrial temperature range from -40°C to +85°C. The WiBear-SF WLAN module features the following key benefits: • Extremely small and efficient footprint which covers 20 x 20 mm of size • Simultaneous use of two different leading wireless standards, the IEEE 802.11b,g WLAN and a full featured Bluetooth IEEE802.15.1 class 2 transceiver. • Micro Access Point feature for building WLAN networks with the maximum number of 8 clients The WiBear-SF WLAN module may be integrated in two ways into customer solutions: • Deploy the processor of the existing design as host controller: The WLAN-SF module is connected to the customer processor by SDIO or G-SPI interfaces. The WLAN stack will run on processor of the existing design. • Add the WiBear-SF WLAN module together with a host controller to an existing design. As an example, the host controller may be a based on ARM9 core. A corresponding reference design is available on request. The host controller selection can consider additional needed interfaces like Ethernet, USB, CAN, or UART. The WiBear-SF WLAN module is designed for industrial solutions in order to connect with already existing WLAN networks on shop floor. Furthermore, an embedded Linux-based Web Server reference application is available to easily implement user-interfaces for WLAN module configuration. The Bluetooth interface supports Bluetooth 2.1 and Enhanced Data Rate (EDR) operation. The WiBear-SF complies with Bluetooth stacks that support SDIO or UART HCI protocol. The WiBear-SF module is a compact one-side assembled design and can be soldered (SMD) onto a customer boards. The availability of the module is guaranteed for minimum of 6 years The universal WLAN module saves time and reduces costs. OEM customers can concentrate on their core competence while adopting this easy to use WLAN module that can enable many wireless applications. For larger quantity orders lesswire can also provide module design-ins. Driver porting to other operating systems can be offered by lesswire.

SDIO-SPI and SDIO -1bit mode are also supported. 2 External sleep clock for WLAN can be generated by internal clock source or may be provided by an external clock source. For Bluetooth operation in power save mode an external sleep clock is required (without power save an external clock for Bluetooth is not necessary). For Bluetooth Power Save mode external sleep clock 32.000 or 32.768 kHz frequency with tolerance ±50ppm is needed (ordinary watch fork quartz crystal conform to ±50ppm requirements at room temperature only, please check temperature characteristics before use). For WLAN external sleep clock any clock source with tolerance ±5000ppm can be used (Note that in this case internal sleep clock with the similar tolerance can be used as well). 3 Can be used as UART_DSR Input (GPIO[3]), UART_DTR Output (GPIO[5]) and as Bluetooth Wake-Up signals.
