The BTM520 and BTM521 are the most advanced low-power, multimedia Bluetooth

in the marketplace. Designed to meet the needs of developers requiring the ultimate Bluetooth audio

performance and flexibility, these modules include everything required for a fully qualified and functional

Bluetooth multimedia application.

In addition to providing best-in-class radio performance, range, and power consumption, the BTM520/521

support all the functionality to run Cambridge Silicon Radio’s Road Tunes and Blue Tunes development

applications. They support the latest Bluetooth Version 2.1+EDR Specification, providing secure simple

pairing that improves security and enhances easy use. (The BTM521 has an integrated high-performance,

multilayer ceramic antenna that achieves open field ranges in excess of 300 meters.)

The modules include a 16 bit stereo codec and microphone input to support both stereo and mono

applications, with the ability to drive stereo speakers. Containing all the necessary audio filtration and

biasing components, these modules only require the addition of speakers, microphone, and push buttons

to make a high-quality Bluetooth stereo product.

The BTM520/521 contain a full, integrated Bluetooth stack along with SPP, HFP 1.5, HSP, AVRCP, and A2DP

profiles, all of which are Bluetooth qualified. Additional profiles could be made available for file transfer,

object exchange, dial up networking, messaging, and phonebook control.Because these modules are

pre-qualified, customers can list and promote their products free of charge on the Bluetooth website.

These modules include an embedded 32-bit, 64-MIPS DSP core within the BC05 that is integrated with

the Bluetooth functionality, allowing the addition of significant product enhancements, such as echo

cancellation, noise reduction, and audio enhancement using additional soft codecs. The availability of the

16MB of flash memory in the module allows complex functionality to be included. DSP routines can be

licensed through a number of specialist partners.

To speed product development and integration, Laird Technologies has developed a comprehensive AT command

interface that simplifies application development, including support for audio and headset functionality.

Combined with a low-cost development kit, Laird Technologies’ Bluetooth modules provide faster time to market.
