CYW20734
Single-Chip Bluetooth Transceiver for
Wireless Input Devices
The Cypress CYW20734 is a Bluetooth 4.1-compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver.
Manufactured using the industry's most advanced 40 nm CMOS low-power process, the CYW20734 employs the highest level of
integration to eliminate all critical external components, thereby minimizing the device's footprint and the costs associated with
implementing Bluetooth solutions.
The CYW20734 is the optimal solution for applications in wireless input devices including game controllers, remote, keyboards, and
joysticks. Built-in firmware adheres to the Bluetooth Low Energy (BLE) profile and the BLE Human Interface Device (HID) profile.
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.
