BTM510/511
Bluetooth
®
Multimedia Module
The BTM510 and BTM511 are low-power Bluetooth
®
modules designed for adding robust
audio and voice capabilities. Based on the market-leading Cambridge Silicon Radio BC05
chipset, these modules provide exceptionally low power consumption with outstanding range.
Supporting the latest Bluetooth
®
Version 2.1+EDR specifi cation, these modules provide the
important advantage of secure simple pairing that improves security and enhances easy use.
At only 14mm x 20mm, the compact size of the BTM510 makes it ideal for battery-powered
or headset form factor audio and voice devices. With a 16-bit stereo codec and microphone
inputs to support both stereo and mono applications, these modules also contain a full,
integrated Bluetooth
®
-qualifi ed stack along with SPP, HFP 1.5, HSP, AVRCP, and A2DP
profi les. Customers using these modules may list and promote their products free of charge
on the Bluetooth
®
website.
The BTM510/511 modules include an embedded 32-bit, 64-MIPS DSP core within the BC05.
This is integrated with the Bluetooth
®
functionality which allows designers to add signifi cant
product enhancements including features such as echo cancellation, noise reduction, and
audio enhancement using additional soft codecs. The availability of the 16MB of fl ash memory
in the module allows complex functionality to be included. DSP routines can be licensed
through a number of specialist partners. Typical applications for these modules include
Bluetooth
®
stereo headsets, VoIP phones, and wireless audio links.
To speed product development and integration, Laird Technologies has developed a
comprehensive AT command interface that simplifi es application development, including
support for audio and headset functionality. Access to GPIO pins allows mapping for direct
connection to actuator buttons on headsets. Combined with a low-cost development kit,
Laird Technologies’ Bluetooth
®
modules provide faster time to market.
