CYW20735 Single-Chip Bluetooth Transceiver for Wireless Input Devices The Cypress CYW20735 is a Bluetooth 5.0-compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver. Manufactured using the industry s advanced 40 nm CMOS low-power process, the CYW20735 employs high levels of integration to minimize external components, reducing the device footprint and the costs associated with implementing Bluetooth solutions. The CYW20735 is the optimal solution for applications in wireless input devices including game controllers, remote controls, 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 Cypress 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. Table 1.
