AIROC™ CYW20721 Bluetooth® and Bluetooth® LE System on Chip
The CYW20721 is a Bluetooth® 5.1-compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver with Bluetooth® LE, EDR and BR. The device is intended for use in audio, IoT, sensors (medical, home, security, and so forth) and human interface device (HID) applications. Manufactured using an advanced 40 nm CMOS low-power fabrication process, the CYW20721 employs high level of integration to reduce external components, thereby minimizing application footprint and costs.

RX sensitivity -95.5 dBm (Bluetooth LE)
Peripherals
16 GPIOs on QFN package
40 GPIOs on WLCSP package
4 GPIOs support 16 mA and 8 mA sink at 3.3V and 1.8V respectively
6x 16-bit PWMs
Programmable key-scan matrix interface, up to 8x20 key-scanning matrix
Watchdog timer (WDT)
1x peripheral UART, 1x UART for programming and HCI
2x SPI (master or slave mode) blocks (SPI, Quad SPI, and MIPI DBI-C)
1x I2C master
1x 28-channel ADC (10-ENoB for DC measurement and 12- ENOB for Audio measurement
