Details Information

 Introduction

F21AUUM13-W1 is a highly integrated module 802.11a/b/g/n/ac 1T1R USB2.0 WLAN controller. It combines a WLAN MAC, a 1T1R capable WLAN baseband, BT Protocol Stack(LM,LL, and LE), BT baseband, modem, and WLAN/BT RF in the module. The module provides a complete solution for a high throughput performance integrated wireless LAN and Bluetooth device. The F21AUUM13 WLAN baseband implements OFDM with 1 transmit and 1 receive path and is compatible with the 802.11ac specification. Features include one spatial stream transmission, short guard interval(GI) of 400ns, spatial spreading, and transmission over 20MHz, 40MHz and 80MHz channel bandwidth. The F21AUUM13 Bluetooth controller complies with Bluetooth core specification v4.0, and supports dual mode(BR/EDR+AMP+LOW Energy Controllers). It is compatible with previous versions, including v2.1+EDR and v3.0+HS. For BR/EDR, it supports scatternet topology and allows four active links in slave mode, or links in master mode. For Low Energy, it supports multiple states and allows to link in BR/EDR and LE modes simultaneously.
