CYW43236BKMLGT, categorized as one of the RF Transceiver ICs, is a Wi-Fi SoC (System-on-Chip) with an integrated IEEE 802.11b/g/n MAC/baseband/radio suitable for low-power wireless applications. It integrated diverse peripheral interfaces (like a USB2.0 host/device controller, UART, SPI, I2C, PCM, JTAG, and SDIO) into a single chip that strongly simplifies the design of low-power, low-cost, highly integrated single-chip, robust and reliable Wi-Fi designs. This section will discuss the application field and working principle of this IC.

Application Field

CYW43236BKMLGT is suitable for applications that require a low cost, low power, rich features, and high degree of integration. It can be used in a wide range of applications, including Wi-Fi enabled consumer and home appliances, multimedia streaming devices, wireless speakers and microphones, handheld games, RFID tags, medical electronic devices, automotive infotainment systems, and home automation systems, etc. It is also suitable for building state-of-the-art Wi-Fi enabled systems like wireless internet hotspots, point-to-point bridges, etc. Moreover, this RF Transceiver IC also supports 802.11n with MIMO (Multiple Input and Multiple Output) technique which can provide higher data rate and better user experience.

Working Principle

CYW43236BKMLGT includes a baseband and radio section that provides Wi-Fi 802.11b/g/n functionality in regulatory domains around the world. It includes a dedicated digital baseband processor, digital signal processor (DSP), as well as a MAC with an integrated crypto-coprocessor which makes it a highly integrated SoC for Wi-Fi. This chip uses a dual-band 2.4GHz/5GHz 802.11n radio transceiver with up to 2x2 MIMO technology support (300Mbps PHY rate) and offers low power consumption. The data rate for 802.11b/g is up to 54Mbps. An integrated power amplifier provides high transmit power (around 20dBm) and high receive sensitivity for exceptional wireless performance.

When it comes to operation, the transmitter component of CYW43236BKMLGT will first collect and encode data delivered from the baseband to the RF channels. This chip passes the frame to the physical layer for coding, interleaving, bit stuffing, and scrambling. Then the signal is modulated and is sent to the power amplifier with a specified power level. After that, the signal is up-converted from baseband to RF and transmitted by the antenna through air. In the receiver section, the signal is first down-converted from RF to baseband and then the signal is demodulated. Finally, the signal is decoded and then it passes through the deinterleaver and the bit un-stuffer. The decoded frame is then delivered to the MAC via the baseband.

Conclusion

In conclusion, CYW43236BKMLGT is a feature-rich Wi-Fi RF Transceiver IC that is suitable for a wide range of low-power wireless applications. It offers a high degree of integration by integrating diverse peripheral interfaces (like a USB2.0 host/devices controller, UART, SPI, I2C, PCM, JTAG, and SDIO) into a single chip and also supports 802.11n with MIMO technology. This chip is suitable for applications enabling them to provide exceptional wireless performance, with low power consumption and low cost.
