CYW43228KMLG Application Field and Working Principle
The CYW43228KMLG is a wireless connectivity system-on-chip (SoC) transceiver IC from Cypress Semiconductor. It is an dual-band, single-stream Wi-Fi radio based on the IEEE 802.11n standard that operates in both the 2.4GHz and 5GHz bands. It is a single-chip solution that integrates a complete 2.4GHz / 5GHz radio plus an ARM Cortex-R4F microcontroller subsystem, a baseband processor, and an on-chip power amplifier and low-noise amplifier. This device is designed to enable Wi-Fi applications, from simple embedded wireless sensors to complex wearable devices. The CYW43228KMLG is ideal for Internet of Things (IoT) applications and wireless audio/video streaming.
Proposed Architecture and Modules
The architecture of the CYW43228KMLG is simplified into three major modules, namely the ARM Cortex-R4F microcontroller subsystem, the baseband processor, and the 2.4GHz/5GHz radio. The ARM Cortex-R4F microcontroller subsystem is responsible for handling high-level Wi-Fi protocol stack operations, such as TCP/IP, while the baseband processor is responsible for the low-level physical layer (PHY) operations, such as FSK and OFDM modulation/demodulation and packet communication.The 2.4GHz/5GHz radio is responsible for modulation, amplification and RF signal generation and reception. It contains a variety of transmit/receive components, such as the power amplifier, low-noise amplifier, mixers, band-pass filters and transmitter/receiver antennas. The radio is also responsible for detecting Wi-Fi networks and managing radio channel parameters. The CYW43228KMLG also includes an on-chip voltage regulator and a number of general-purpose input/outputs (GPIOs).
Working Principle
The CYW43228KMLG transceiver IC works by first detecting the presence of Wi-Fi networks in the environment, using the on-chip radio. Once a Wi-Fi network is detected, the ARM Cortex-R4F microcontroller extracts the network information and configures the baseband processor to communicate with the Wi-Fi network. The baseband processor then sets up a two-way communication link with the Wi-Fi network and manages packet communication between the two devices. Data is transmitted and received using either FSK or OFDM modulation, depending on the distance to the Wi-Fi network. The 2.4GHz/5GHz radio then provides the necessary RF signal amplification and transmission/reception functions. The data is then further processed by the baseband processor and routed to the appropriate destination in the end device.
Conclusion
The CYW43228KMLG is a dual-band, single-stream Wi-Fi radio based on the IEEE 802.11n standard that operates in both the 2.4GHz and 5GHz bands. The device is designed to enable Wi-Fi applications, from simple embedded wireless sensors to complex wearable devices. The proposed architecture and working principle of the CYW43228KMLG transceiver IC demonstrate its advantages in terms of power efficiency, low electromagnetic interference, cost-effectiveness and scalability. The combination of its highly integrated architecture and advanced features make the CYW43228KMLG an ideal choice for a wide range of Internet of Things (IoT) and wireless streaming applications.
