New Product


January 30, 2021 by Mouser Electronics

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.


Cypress Semiconductor’s CYW20735 is a highly integrated single-chip Bluetooth MCU that provides a small footprint solution for wireless input devices such as game controllers, remote controls, keyboards, and more. 

The CY20735 includes an MCU subsystem based on a 96MHz Arm Cortex-M4 that runs the Bluetooth stack and application firmware and a separate Bluetooth subsystem that complies with Bluetooth 5.0 and supports LE 2Mbps data rates. The device also has a built-in security engine. 

The Bluetooth radio offers excellent range and low power consumption, with programmable transmit power up to +12dBm and -94.5dBm receive sensitivity paired with low receive and transmit currents. The CY20735 operates from a 1.625V to 3.63V input and integrates buck and LDO regulators as well as a software-controlled power management unit to support ultra-low-power applications.
