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 speci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-qualied stack along with SPP, HFP 1.5, HSP, AVRCP, and A2DP
pro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 signicant
product enhancements including features such as echo cancellation, noise reduction, and
audio enhancement using additional soft codecs. The availability of the 16MB of 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 simpli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.
