Preliminary Datasheet IS2020S Bluetooth 4.1 Multimedia SOC Phone: 886-3-577-8385 Website: www.issc-tech.com Draft 0.9 Mar 10, 2014 GENERAL DESCRIPTION IS2020S 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 the basic CVSD encoding and decoding but also the 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 voltage sensor for battery, battery charger, a switching regulator 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 following profiles : - Hands Free 1.6 - Headset 1.1 - A2DP 1.2 - AVRCP 1.5 - SPP 1.0  Integrated 16/32 bits DSP core running up to 72MHz that supports: - Dual microphone noise suppression - Echo cancelation - SBC/AAC_LC audio format decoding - Automatic volume control for speaker output  Integrated a 20-bit 98dB SNR ( A-weighted) stereo DAC  Connections to two phones with HFP/A2DP profiles  Built-in four languages ( Chinese/ English/ Spanish/ French) voice prompts  Ultra low power consumption under 10mA for SCO/A2DP link  Capable charging voltage from an empty battery and sustain a direct DC input voltage up to 7V  Charging current up to 350mA  7 mm x 7 mm 56 QFN package APPLICATIONS  Bluetooth stereo headset  Bluetooth stereo speaker  Bluetooth stereo speaker phone  Bluetooth car audio unit ISSC CONFIDENTIAL Preliminary Datasheet IS2020S Bluetooth 4.1 Multimedia SOC Phone: 886-3-577-8385 Website: www.issc-tech.com Draft 0.9 Mar 10, 2014 Table of Contents 1 KEY FEATURES ................................................................................................................................... 3 2 PIN ASSIGNMENTS .............................................................................................................................. 6 3 TRANSCEIVER ................................................................................................................................... 10 4 MICROPROCESSOR .......................................................................................................................... 11 5 AUDIO .................................................................................................................................................. 12 6 POWER MANAGE UNIT ..................................................................................................................... 13 7 GENERAL PURPOSE IOS .................................................................................................................. 15 8 SPECIFICATIONS ............................................................................................................................... 16 9 PACKAGE ........................................................................................................................................... 28 ISSC CONFIDENTIAL Preliminary Data Sheet IS2020S - 3 - 1 Key Features System Specification  Compliant with Bluetooth Specification v.4.1 (EDR) in 2.4 GHz ISM band 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.

Standard Requirement 15.247(b)(4) requirement: The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6dBi. Except as shown in paragraph (c) of this section. if transmitting antennas of directional gain greater than 6dBi are used. the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1). (b)(2). and (b)(3) of this section. as appropriate. by the amount in dB that the directional gain of the antenna exceeds 6dBi. 2. Limits According to KDB447498 General RF Exposure Guidance v05 Report No. : LK14KR-0895E-2 Page 2 of 2 Shenzhen Laker Testing Technology Co.,Ltd 4D，Block 1,Sunshine Huayi Building,Nanhai West Road,Nanshan, Shenzhen, China TEL：0755-86307736 FAX：0755-86307356 3. EUT RF Exposure The Max Conducted Peak Output Power is 0.52dBm(1.13mW) in middle channel, and the Max Conducted Average Output Power is less than 1.13mW. The best case gain of the antenna is 0dBi. 0 dBi logarithmic terms convert to numeric result is nearly 1. According to the formula. calculate the EIRP test result: EIRP< P x G = 1.13mW x 1 = 1.13mW ① SAR requirement: Limit = 10mW @ 5mm ② ; ① < ②. So the SAR report is not required.
