Overview

The CYW20719B2KUMLG is an ultra-low-power Bluetooth 5.1 SoC featuring a high-performance 96MHz Arm Cortex-M4 core with a floating-point unit (FPU). It integrates a 2.4GHz transceiver supporting Bluetooth LE, BR, and EDR modes alongside 1MB of Flash and 512kB of RAM for complex application code and data buffering. This device is optimized for dual-mode Bluetooth applications that require a balance of computational power and long battery life.

Why Choose This Part

It offers superior flexibility by supporting both Bluetooth Low Energy and Classic (BR/EDR) simultaneously on a single chip. The integration of 1MB Flash and 512kB RAM eliminates the need for external memory in many designs, while the Cortex-M4 FPU allows for sophisticated signal processing at the edge.

Applications

Wearable Health Monitors
Utilizes the -95.5dBm sensitivity and FPU for processing biometric sensor data while maintaining a low-power Bluetooth LE connection.
Wireless Audio Interfaces
Leverages integrated I2S, PCM, and PDM interfaces for digital audio streaming over Bluetooth Classic (BR/EDR).
Home Automation Hubs
Uses the 40 GPIOs and hardware security engine to interface with multiple sensors and act as a secure bridge for smart home ecosystems.
Industrial IoT Sensors
Deploys in battery-operated monitoring equipment where the 1.6uA sleep current extends service intervals.

Getting Started

Developers should use the ModusToolbox software environment, which provides the necessary libraries and Bluetooth stacks for the CYW20719. Evaluation can be performed using the CYW20719B2-EVAL-01 kit to prototype hardware interfaces and test RF performance. Practical firmware development is conducted via the integrated SWD and JTAG interfaces.
