CYW20737
Single-Chip Bluetooth Low Energy-Only
System-On-Chip with Support for Wireless Charging
The Cypress CYW20737 is an advanced Bluetooth low energy SoC that supports wireless charging profile, includes advanced security
features and introduces new software support for NFC pairing via a tag. The CYW20737 is designed to support the entire spectrum
of Bluetooth Smart use cases for the medical, home automation, accessory, sensor, Internet Of Things, and wearable market
segments.
The CYW20737 radio has been designed to provide low power, low cost, and robust communications for applications operating in the
globally available 2.4 GHz unlicensed Industrial, Scientific, and Medical (ISM) band.
The single-chip Bluetooth low energy SoC is a monolithic component implemented in a standard digital CMOS process and requires
minimal external components to make a fully compliant Bluetooth device. The CYW20737 is available in a 32-pin, 5 mm × 5 mm 32-
QFN package as well as BGA SIP. CYW20737 is supported in WICED SDK 2.x.
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.
