2013/10/08 18:30 1/10 WizFi250 Datasheet WizFi250 Datasheet Introduction The WizFi250 is a small size wireless module. The WizFi250 provides for the highest-level integration, featuring 802.11b/g and 802.11n. It includes a 2.4 GHz WLAN CMOS power amplifier (PA) that meets the output power requirements of most handheld systems. Along with the integrated power amplifier, the WizFi250 also includes integrated transmit and receive baluns, further reducing the overall solution cost. The small size & low profile physical design make it easier for system design to enable high performance wireless connectivity without space constrain. Hardware WAPI acceleration engine, AES, TKIP, WPA and WPA2 are supported to provide the latest security requirement on your network. For the software and driver development, WIZnet provides extensive technical document and reference software code for the system integration. 2013/08/28 09:43 · ssekim Features ● ● ● ● ● ● ● ● ● ● ● ● ● ● Single band 2.4GHz IEEE 802.11b/g/n Integrated RF power amplifier Supports wireless data rates up to 65Mbit/s 1MB Flash Memory, 128KB SRAM, 1MB Serial Flash Supports per packet Rx Antenna diversity Low power consumption & excellent power management performance extend battery life.

Operating Temperature -20° to 85° Celsius Humidity range Max 95%, Non condensing, relative humidity * The maximum operating ambient temperature range can up to 85°, but exposure to absolute-maximum-rated conditions may cause performance degradation and affect device reliability. So we recommend -20° to 75° for the best performance. Voltage Power supply for the WizFi250 module will be provided by the host via the power pins. http://wizwiki.net/wiki/ Printed on 2013/10/08 18:30 2013/10/08 18:30 5/10 WizFi250 Datasheet Symbol Parameter Min Typ.
