IS2015S

Brochure IS2015S Bluetooth 4.1 Mono Audio Speaker SOC GENERAL DESCRIPTION IS2015S is a compact, highly integrated, CMOS single-chip RF and baseband IC for preliminary Bluetooth v4.1 with Enhanced Data Rate 2.4GHz applications. This chip is fully compliant with Bluetooth specification and completely backward-compatible with Bluetooth 3.0, 2.0 or 1.2 systems. It incorporates Bluetooth 1M/2M/3Mbps RF, single-cycle MCU, MODEM, UART interface, and ISSC’s own Bluetooth software stack to achieve the required BT v4.1 with EDR functions. To provide the superior audio and voice quality, it also integrates a DSP co-processor, a PLL, and a CODEC dedicated for voice and audio applications. For voice, not only basic CVSD encoding and decoding but also enhanced noise reduction and echo cancellation are implemented by the built-in DSP to reach the better quality in the both sending and receiving sides. For enhanced audio applications, SBC and AAC (optional) decoding functions can be also carried out by DSP to satisfy Bluetooth A2DP requirements. In addition, to minimize the external components required for portable devices, a build-in class-D amplifier for audio output, a voltage sensor for battery, battery charger and LDO are integrated to reduce BOM cost for various Bluetooth applications. FEATURES  Support preliminary Bluetooth v4.1 function and backward compatible with BT3.0, 2.0 and 1.2.  ISSC’s own Bluetooth software stack for the headset or speaker application. It supports follow...
