Atheros AR3000 - ROCm� Solutions for Bluetooth�
Radio-On-Chip for Mobile (ROCm) Products
The AR3000 family consists of Bluetooth� solutions based
on the Atheros ROCm platform for high-performance mobile
and embedded wireless products. The Atheros ROCm
platform gives customers unsurpassed ability to:
- Build the most power-efficient devices
- Design for the smallest form factor applications
- Achieve the most cost-effective designs
- Enhance ease of design
- Deliver Atheros-class performance in a wide array of
mobile devices
AR3031 Technology
Overview
The Atheros AR3031 SoC offers
unmatched low-power in a highly flexible, single-chip
Bluetooth v2.1 + EDR solution for mono headset
applications. The SoC includes an Atheros radio for
Bluetooth, a 32-bit CPU, dual 1.2v voltage regulators,
I2C interface to an external EEPROM, internal LPO, on
chip PLL, and 314 KB of ROM with 28 KB of RAM. It also
has a PCM interface that supports an external audio
CODEC.
The AR3031 features unmatched
low-power achieved through an array of Atheros design
protocols and techniques to deliver extended usage
between charges. With fully embedded Headset Profile
v1.1 and Handsfree Profile v1.5, the AR3031 delivers
optimal design ease and flexibility, resulting in
time-to-market advantage. Atheros’ Headset Studio
enables product designers to easily customize features
such as switches and LED indicators to drive product
differentiation. The AR3031 5mm x 5mm QFN package
provides a low-cost, small footprint solution to allow
customers to build highly competitive headset designs.
