Innovative Technology for a Connected World Multimedia Module BTM520/521 The BTM520 and BTM521 are the most advanced low-power, multimedia 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 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 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. global solutions local support TM USA Europe Asia: Innovative Technology for a Connected World Multimedia Module BTM520/521 • Fully featured Bluetooth multimedia module • Supports CSR Road Tunes and Blue Tunes applications • Bluetooth v2.1+EDR • Supports mono and stereo headset applications • Adaptive frequency hopping to cope with interference from other wireless devices • 32bit Kalimba DSP for enhanced audio applications • Support for secure simple pairing • External or internal antenna options • HSP, HFP, A2DP and AVRCP audio profiles • HDP profiles later release • 16 bit stereo codec and microphone input • Integrated audio amplifiers for driving stereo speakers • Comprehensive AT interface for simple programming • Bluetooth End product qualified • Compact size • Class 1 output 8dBmi • Lowest power operation with high efficiency internal switch mode supply. • Wi-Fi coexistence hardware support APPLICATION AREAS • High quality stereo headsets • Hands-free devices • Wireless audio cable replacement • MP3 and music players • Phone accessories • VoIP products • Aftermarket automotive Innovative Technology for a Connected World Multimedia Module BTM520/521 CATEGORIES Wireless Specification Host Interface Audio Interfaces DSP FEATURE Frequency Max Transmit Power Receive Sensitivity Data Rates UART Data Transfer Rate UART Codec Microphone Integrated Kalimba DSP Profiles Supply Voltage Power Consumption Supply I/O Current Consumption Coexistence / Compatibility Connections Programming API Wi-Fi External Antenna Internal Antenna Physical Dimensions ORDERING INFORMATION BTM520 Bluetooth Multimedia Plus Module external antenna BTM521 Bluetooth Multimedia Plus Module with integrated antenna DVK- BTM520 Evaluation Board with BTM520 DVK- BTM521 Development Kit with integrated antenna The details contained within the document are subject to change.
