IS1621N Bluetooth v2.1+EDR Multimedia 1. General Description ISSC IS1621N is a compact, high integration, ultra-low cost, CMOS single-chip RF + baseband IC for Bluetooth v2.1+EDR (Enhanced Data Rate) 2.4GHz applications. This chip is fully compliant with Bluetooth specification and completely backward-compatible with BT1.1, 1.2 or 2.0 systems. It incorporates Bluetooth 1M/2M/3Mbps RF, single-cycle 8051, TX/RX modem, memory controller, task/hopping controller, UART interface, and ISSC Bluetooth software stack to achieve the required BT v2.1+EDR functions. To provide the best audio and voice quality, it also integrates a DSP co-processor, and a high performance stereo CODEC to handle voice and audio applications. For voice, not only basic A-law/µ-law/CVSD encoding /decoding but also enhanced noise reduction and echo cancellation are implemented by the built-in audio processor to reach the best quality in the both sending and receiving sides. For enhanced audio applications, SBC or MP3 encoding/decoding functions are also carried out by ...
