CYW20736
Single-Chip Bluetooth Low Energy-Only
System-On-ChipwithSupportforWirelessCharging
The Cypress CYW20736 is a an advanced Bluetooth Low Energy (aka Bluetooth Smart) SoC that supports wireless charging. The
CYW20736 is designed to support the entire spectrum of Bluetooth Smart use cases for the medical, home automation, accessory,
sensor, Internet Of Things, and wearable market segments.
The CYW20736 radio has been designed to provide low power, low cost, and robust communications for applications operating in the
globally available 2.4 GHz unlicensed Industrial, Scientific, and Medical (ISM) band.
The single-chip Bluetooth low energy SoC is a monolithic component implemented in a standard digital CMOS process and requires
minimal external components to make a fully compliant Bluetooth device. The CYW20736 is available in a 32-pin,
5 mm × 5 mm 32-QFN package as well as WLCSP and die packages.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion,
there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides
Cypress ordering part number that matches an existing IoT part number.
