Datasheet for Qualcomm Atheros AR3011

The Only Bluetooth Solution Optimized for Computing Applications

AR3011 Product Overview
The Qualcomm AR3011 is a highly integrated, all-CMOS, single-chip solution specifically designed for PC applications. The Qualcomm AR3011 supports both the Bluetooth 2.1 and 3.0 + HS specification versions. 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. AR3011 also utilizes Qualcomm Universal Wireless Cooperation™ support for maximum performance with Qualcomm WLAN combo design.
The Qualcomm AR3011 supports the standard HCI USB interface, which makes it compatible with any upper layer Bluetooth stack. Microsoft software is available for Win7, Vista, and XP. Linux BlueZ is also well supported.
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. Qualcomm provides a complete Bluetooth software solution.

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.
