CYW20733
Single-Chip Bluetooth Transceiver
Wireless Input Devices
The Cypress CYW20733 is a Bluetooth 3.0 + EDR compliant, stand-alone baseband processor with an integrated 2.4 GHz trans-
ceiver. The device is ideal for applications in wireless input devices including game controllers, keyboards, and joysticks. Built-in
firmware adheres to the Bluetooth Human Interface Device (HID) profile and Bluetooth Device ID profile specifications. The
CYW20733 radio has been designed to provide low power, low cost, and robust communications for applications operating in the
globally available 2.4 GHz unlicensed ISM band. It is fully compliant with the Bluetooth Radio Specification 3.0 + EDR. The single-
chip Bluetooth transceiver is a monolithic component implemented in a standard digital CMOS process and requires minimal exter-
nal components to make a fully compliant Bluetooth device. The CYW20733 is available in three package options: a 81-pin, 8 mm ×
8 mm FBGA, a 121-pin, 9 mm × 9 mm FBGA, and a 56-pin, 7 mm x 7 mm QFN.
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.
