CYW20819 Ultra-Low-Power Bluetooth® 5 MCU Eva

The Cypress CYW20819 is a best-in-class Bluetooth 5 single-chip solution targeted at Bluetooth Mesh, audio, voice, wearables, HID, home automation, and a wide range of other Internet of Things (IoT) applications. The CYW20819 fully implements the Bluetooth Mesh 1.0 specification and employs the highest level of integration to eliminate external components, allowing device makers to reduce product footprints and slash costs.

The CYW20819 integrates ultra-low-power (ULP) BLE along with the capability to add audio functionality to enhance the user experience for wearables and trackers. It also provides best-in-class receiver sensitivity for both BLE and EDR. Using advanced design techniques and process technology to reduce active and idle power, the CYW20819 also addresses the needs of a diverse class of low-power Bluetooth 5-enabled devices that require minimal power consumption and compact size.

Available now is an evaluation kit to develop with all of CYW20819’s industry-leading feature sets.
