WiFi-EZ200

Description

Introduce the first IEEE802.11b/g/n WLAN and Bluetooth combo module-EZ200. The module is targeted to mobile devices including, Portable media players(PMPs),PDA, and personal gaming devices, mobile phones which need small footprint package, low power consumption, multiple OS support, the performance during the simultaneous use of IEEE802.11 and Bluetooth with a single antenna. By using EZ200, the customers can easily enable the Wi-Fi and BT embedded application with the benefits of high design flexibility, short development cycle, resulting in greatly reduced development risk, costs, and quick time-to-market.
