Infineon/CYPRESS CYW20738A2KML3G

The Cypress CYW20738 is a Bluetooth low energy compliant, stand - alone baseband processor with an integrated 2.4 GHz transceiver. 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.
