Data Sheet

Beijing Eswin Technology Co.,Ltd
1. Overview
The SoC is a 2.4GHz IEEE 802.11b/g/n Wi-Fi single chip solution with
standard security features. With optimized power and RF performance,
robustness, versatility, reliability, various power profiles, full features and
functions, the chip is designed for a wide variety of applications, including
Smart home, Wearable devices and IoT (Internet of Things).
It integrates a 32-bit microcontroller, 802.11b/g/n Wi-Fi baseband, a 2.4GHz
RF transceiver with antenna switch, RF balun, PA (power amplifier), LNA
(low noise receive amplifier) and filters, ample memory space, a
general-purpose ADC(Analog-to-Digital Converter), 6-channel PWM(Pulse
Width Modulation), flexible I/O interfaces, and multi-stage power
management module. With the highly-integrated SoC, few external
components and minimal PCB(Printed Circuit Board) area are needed to build
Wi-Fi applications.
The SoC has many features of the state-of-the-art low power chips, such as
good resolution clock gating, advanced management of multi-stage power
modes, and dynamic power scaling.
The chip uses CMOS for single-chip fully-integrated radio and Baseband, and
also integrates advanced calibration circuitries that allow the solution to
dynamically adjust itself to remove external circuit imperfections or adjust to
changes in external conditions.
