CYW20738A2KML3G Application Field and Working PrincipleThe Cypress CYW20738A2KML3G is a highly advanced RF transceiver integrated circuit (IC) designed for use in wireless personal area networks (WPANs). This IC is the first of its kind to use a 65nm process and has been designed to enable high-speed, bidirectional wireless communication for data rates up to 3.25 Gbps. It is part of the broad portfolio of Cypress products designed for WPANs and is the most advanced IC in this family.The CYW20738A2KML3G is specifically designed for use in IEEE 802.15.4-compliant applications including ZigBee, Thread, 6LoWPAN, and other Industrial Internet of Things (IIoT) networks. By utilizing advanced modem design, it is able to achieve excellent receiving sensitivity performance, while simultaneously delivering high data speeds and robustness against interference. It is compliant with the latest versions of IEEE 802.15.4-2003, IEEE 802.15.4-2006, and IEEE 802.15.4-2016. This IC also includes a 32-bit Cortex-M0 microcontroller that can be used to customize the application, allowing for a variety of unique features.The CYW20738A2KML3G is a highly integrated, low-power, single-chip device designed to provide the highest level of performance for wireless communications. It contains an advanced RF transceiver, embedded ARM Cortex-M0 microcontroller, baseband/MAC processing, security, and system interfaces. The main features of the CYW20738A2KML3G are:• High data rates – Up to 3.25 Gbps• High sensitivity – -97 dBm@1 Mbps, -97 dBm@2 Mbps• Low power consumption – 0.7 mA/MHz maximum power• Small footprint – 7 x 7 mm package• Enhanced security – AES-128, RSA-1024, ECC-256, and SHA-256• I/O interfaces – UART, I2C, SPI, USB, JTAGThe CYW20738A2KML3G can achieve data speeds up to 3.25 Gbps through the use of a highly efficient modem subsystem that supports both IEEE 802.15.4-2003 and IEEE 802.15.4-2006 protocols. The modem subsystem is composed of a frequency synthesizer, baseband modem, modulator/demodulator, and power amplifier. The frequency synthesizer is used to tune the transceiver to the desired frequency and control the channel bandwidth. The baseband modem contains a digital analog converter (DAC) and digital pulse receiver (DPR) to generate and receive digital signals with low noise and high sensitivity. The modulator/demodulator is used to convert the digital signals to radio frequency (RF) and vice versa. The power amplifier is used to amplify the RF signal so that it can be transmitted over long distances.The CYW20738A2KML3G also contains embedded security features including AES-128, RSA-1024, ECC-256, and SHA-256 to ensure that communications are secure. The IC also contains various system interfaces, such as UART, I2C, SPI, USB, and JTAG, to allow external devices to be connected and interact with the IC.The CYW20738A2KML3G is an ideal solution for WPANs and IIoT applications that require high data throughput, low power consumption, and enhanced security. It is the perfect choice for any application that demands reliable wireless communication without sacrificing the performance or security of the network.
