Cypress CYW43362KUBGT Single-Chip Integrated 2.4GHz IEEE 802.11™ Wi-Fi 4 Chip

With the rapid growth of the smart home market, the CYW43362KUBGT, a high-performance wireless SoC chip, is becoming a core solution for IoT device design. The chip's integrated dual-band Wi-Fi 6/Bluetooth 5.2 functionality enables devices equipped with the CYW43362KUBGT to simultaneously handle HD video streaming and low-latency control commands.

In terms of technical parameters, the CYW43362KUBGT demonstrates significant advantages: support for 160MHz channel bandwidth, 1024-QAM modulation technology, and -98dBm receive sensitivity. These features enable smart gateway devices using the CYW43362KUBGT to maintain stable connectivity even in dense flat environments. Test data shows that an access point designed based on the CYW43362KUBGT can sustain concurrent transmissions from 50+ end devices at the same time.

The following are the key features of the CYW43362KUBGT:
1. High integration and wireless communication capability
The CYW43362KUBGT features a single-chip design that integrates the IEEE 802.11 b/g/n standards and supports the Wi-Fi 4 protocol in the 2.4 GHz band, as well as a built-in WLAN CMOS power amplifier (PA) and low-noise amplifier (LNA), which meets the needs of handheld devices in terms of output power and receive sensitivity112 .
The CYW43362KUBGT chip also supports external coexistence solutions (e.g., Bluetooth, Zigbee) and optimises bandwidth allocation for multiple wireless technologies via the IEEE 802.15.2 standard, making it suitable for smart home and industrial IoT scenarios1.

2. Flexible interface and communication protocol support
The CYW43362KUBGT provides two host interfaces, SDIO v2.0 (50 MHz in 4-bit mode) and SPI (up to 50 MHz), and supports a raw data transfer rate of 200 Mbps, making it suitable for embedded systems requiring high-speed communication112.
In addition, its built-in ARM Cortex-M3 processor and on-chip memory support firmware field upgrades and future expansion to advanced features such as Wi-Fi Voice Enterprise1.

3. Low power consumption and dynamic power management
The CYW43362KUBGT adopts dynamic power management technology, supports a wide voltage input from 2.3V to 4.8V, and optimises power efficiency with internal switching regulators to significantly extend battery life.112 Its low-power design is particularly suitable for energy-sensitive applications such as security cameras and wearable devices.1 4.

4. Hardware design and debugging adaptation
At the hardware level, the CYW43362KUBGT is packaged in a 69-bump WLBGA package (4.52 mm × 2.92 mm), a compact package suitable for space-constrained devices.1 Attention should be paid to the configuration of the SDIO interface, the stability of the power supply, and the interrupt pin settings during debugging.
