The AIROC CYW43022 from Infineon Technologies is a 1x1 2.4/5 GHz Wi-Fi 5 (802.11ac) + Bluetooth 5.4 Combo Chip. It has been designed for IoT designs that require minimal power consumption and compact size. This combo chip is built on market-proven wireless IP to ensure maximum interoperability and supports concurrent Wi-Fi and Bluetooth connectivity use cases and co-existence. It includes embedded Bluetooth stack and Wi-Fi networking off-loads to save system-level power by handling Bluetooth and Wi-Fi connectivity activities, without the involvement of a host processor.
The CYW43022 has a built-in power amplifier (PA) and low noise amplifier (LNA) switch to support a single antenna shared between Wi-Fi and Bluetooth. It also has an option for an internal 32 kHz low-power oscillator that saves power and bill of materials (BOM) costs. This combo chip integrates SDIO v2.0/v3.0 host interface, SPI host interface, HCI over UART/SPI for Bluetooth communication, and 40 GPIOs for internal connectivity options. It enables Wi-Fi software for RTOS, Linux, and Android designs with support from multiple hosts, reducing the development time.
This chip delivers a transmit power of +18 dBm with a data rate of up to 78 Mbps over the channel bandwidth of 20 MHz. It is available in a wafer-level chip scale package that measures 3.76 x 4.43 mm and is ideal for smart home, smart medical, healthcare, and wearable applications.
