IS2020/21/23/25 SoC
Bluetooth® 4.1 Stereo Audio SOC
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 Hardware
Fully Bluetooth 4.1 (EDR) system in 2.4 GHz
ISM band.
Combined TX/RX RF terminal simplifies
external matching and reduces external
antenna switches.
Max. +4dBm output power with 20 dB level
control from register control.
Built-in T/R switch for Class 2/3 application
To avoid temperature variation, temperature
sensor with temperature calibration is utilized
into bias current and gain control.
Fully integrated synthesizer has been created.
There requires no external VCO, varactor
diode, resonator and loop filter.
Crystal oscillation with built-in digital trimming
for temperature/process variations.
Audio processor
Support 64 kb/s A-Law or -Law PCM format,
or CVSD (Continuous Variable Slope Delta
Modulation) for SCO channel operation.
Noise suppression
Echo suppression
SBC and optional AAC decoding
Packet loss concealment
Build-in four languages (Chinese/ English/
Spanish/ French) voice prompts and 20 events
for each one (This function can be set up in
IS20XXS_UItool.)
Support SCMS-T
Audio Codec
20 bit DAC and 16 bit ADC codec
98dB SNR DAC playback
Built-in 2 channel 2.3W class-D amplifier for a
4Ω speaker (for IS2025S only)
Peripherals
Built-in Lithium-ion battery charger (up to
350mA)
Integrate 3V, 1.8V configurable switching
regulator and LDO
Built-in ADC for battery monitor and voltage
sense.
A line-in port for external audio input
Two LED drivers
Flexible HCI interface
High speed HCI-UART (Universal
Asynchronous Receiver Transmitter) interface
(up to 921600bps)
Package
5x6.5mm2 48QFN package (IS2021S)
7x7mm2 56QFN package (IS2020S, IS2023S)
8x8mm2 68QFN package (IS2025S)
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.
It incorporates Bluetooth 1M/2M/3Mbps RF,
single-cycle 8bit MCU, TX/RX modem, 5-port
memory controller, task/hopping controller,
