                  - Low-cost chip solution

• Deliver Atheros-class performance in a wide array of mobile devices

AR3011 Technology Overview

The Atheros AR3011 is a highly integrated, all-CMOS, single chip Bluetooth® 2.1 + EDR
solution specifically designed for PC applications.  It includes a Bluetooth® EDR radio,
a 32-bit Tensilica CPU, USB 2.0 interface, two 1.2v voltage regulators for analog and digital circuit, auxiliary serial Flash interface, on board PLL, and on board RAM/ROM.  It also has a WLAN coexistence interface to ensure coexistence and co-location with a WLAN solution in the same system.

The Atheros AR3011 supports the standard HCI USB interface which makes it compatible
with any upper layer Bluetooth® stack. It is specially optimized for PC applications and, as a
result, eliminates the need for an external Flash, which further reduces the external component  count and lowers system BOM cost.* The Atheros AR3011 can provide PC ODMs/OEMs with the lowest-cost Bluetooth® solution.

AR3011 utilizes a small, cost-effective 6 mm x 6 mm Quad Flatpack No lead (QFN) package.
A Bluetooth® Qualification Body (BQB) certified reference design is available to customers for
quick turn system integration. Atheros provides a complete BT software solution.
