Micrel IS2008S-203

Bluetooth v4.1 + EDR2,4 ГГц4 дБм

Overview

The IS2008S-203 Mono Audio Chip is a compact, highly integrated, CMOS single-chip RF and baseband IC that is Bluetooth 5 Certified.  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 8bit MCU, TX/RX modem, 5-port memory controller, task/hopping controller, UART interface, and Microchip's own Bluetooth software stack to achieve the required Bluetooth 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 achieve better quality in both sending and receiving sides. For the enhanced audio applications, SBC/AAC_LC 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 battery voltage sensor, battery charger, a switching regulator and LDO are integrated to reduce system BOM cost for various Bluetooth applications.  As the market of portable/wireless speakers demand is increasing, a 1 channel 2.3W class-D amplifier which provides up to 100dB SNR is also built-in to reduce BOM cost and PCB area.
