The BTM520 and BTM521 are the most advanced low-power, multimedia Bluetooth® modules available 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 environments. 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 16Ω 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 complete system implementation.
