1 General Description
1.1 Functional Description
SWL-2900U is the low power USB 2.0 module for 802.11b/g wireless LAN (WLAN) aimed at embedded
applications. SWL-2900U is the USB 2.0 module that adopts a single-chip wireless local area network
(WLAN) medium-access controller (MAC) spread-spectrum baseband processor and 2.4 GHz RF radio.
SWL-2900U supports IEEE 802.11b, an d 80 2. 11g stan d ard s. Data r at es up t o 54 M bp s can b e p rovid ed in
802.11g mode of operation.
The main IC of SWL-2900U includes an 80MHz ARM7 core, 384 KB of on-chip SRAM, and 80 KB of onchip ROM. SWL-2900U is able to host the entire WLAN driver and TCP/IP stack on-chip. This minimizes
development time, cost, and burden on the host processor resou rces making SWL-2900U an ideal WLAN
solution for nomadic application.
SWL-2900U provides crucial power management functionality and requires only a single 5.0 V supply
voltage.
