MM546-EK Evaluation KIT |
The Scope
Bluepacket's MM540/MM546 series Bluetooth audio module comes complete with DSP, stereo CODEC, flash and antenna. It offers superior audio quality, power consumption and radio performance, making it ideal for high quality Bluetooth headset designs and other mono and stereo audio applications. The embedded DSP core is an open platform digital signal coprocessor allowing product-enhancing features such as advance audio decoding (MP3, AAC, AAC+), speech recognition, text-to-speech, echo cancellation and noise reduction.
Utilizing with the latest Bluetooth technology, the MM540/MM546 can connect to other Bluetooth devices such as MP3/MD/CD players, mobile phones, and desktop or notebook computers, PDA etc., in range up to 100 meters.
The MM540 & MM546 are Bluetooth 2.0 compliant that increase throughput, reduce battery consumption and improve security. It provides faster pairing and allows superior performance in the presence of interference from 802.11 (Wi-Fi) wireless devices and other 2.4GHz radios.
The MM540 has 8Mbits flash memory (MM546 has 16Mbits flash memory.) on board for loading custom OEM specific parameters and settings. It provides an efficient method of adding a Bluetooth audio data link to most embedded applications.
There are three platforms available. The MM540 (MM546) is a surface mount PCB module. The MM540-HM-a (MM546-HM-a) is a DIP, through-hole module with on-board chip antenna, and the MM540-HM-c (MM546-HM-c) has an U.FL connector for external antenna.
We also provide the Evaluation KIT, MM546-EK (only 16M version) for your evaluation & test before designing MM510/MM516 into your circuitry.
