CYW20732:SINGLE-CHIP
BLUETOOTH LOW ENERGY-ONLY SOC
The Cypress CYW20732 is a Bluetooth Low-Energy (BLE)-only System-on-a-Chip (SoC).
The CYW20732 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, Scienti c, and Medical (ISM) band.
The single-chip BLE 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 CYW20732 is available in a 32-pin, 5 mm × 5 mm 32-QFN
package.
