CYW20738
Single-Chip Bluetooth Transceiver for
Wireless Input Devices
The Cypress CYW20738 is a Bluetooth low energy compliant, stand-alone baseband processor with an integrated 2.4 GHz trans-
ceiver. It is ideal for wireless input device applications including game controllers, keyboards, remote controls, gestural input devices,
and sensor devices. Built-in firmware adheres to the Bluetooth Human Interface Device (HID) profile and Bluetooth Device ID profile
specifications.
The CYW20738 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 Bluetooth Low Energy Radio Specification.
The single-chip Bluetooth transceiver is a monolithic component implemented in a standard digital CMOS process and requires
minimal external components to make a fully compliant Bluetooth device. The CYW20738 is available in two package options: a 40-
pin, 6 mm × 6 mm QFN and a 64-pin, 7 mm × 7 mm BGA.
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.
