IS2021 - Bluetooth 4.1 Stereo Audio SOC

Download the IS2021 datasheet PDF. This datasheet also covers the IS2020 variant, as both devices belong to the same bluetooth 4.1 stereo audio soc family and are provided as variant models within a single manufacturer datasheet.

Description

Stereo Audio Chip is a compact, highly integrated, CMOS single-chip RF and baseband IC for 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.

Features

  • System Specification.
  • Compliant with Bluetooth Specification v.4.1 (EDR) in 2.4 GHz ISM band.
  • It supports following profiles : - HFP 1.6 - HSP 1.1 - A2DP 1.2 - AVRCP 1.5 - SPP 1.0 - PBAP 1.0 Baseband Hardware.
  • 16MHz main clock input.
  • Built-in internal ROM for program memory.
  • Support to connect to two hosts ( phones, tablets…) with HFP or A2DP profiles simultaneously.
  • Adaptive Frequency Hopping (AFH) avoids occupied RF channels.
  • Fast Connection supported RF Hard.
