Overview

The CYW20719B2KUMLGT is an ultra-low-power Bluetooth 5.1 SoC featuring an integrated 96MHz Arm Cortex-M4 core with a Floating Point Unit (FPU). It combines a high-performance 2.4GHz radio supporting Bluetooth LE, BR, and EDR with 1MB of onboard flash and 512kB of RAM for complex IoT application logic. The device is designed for battery-operated devices requiring robust wireless connectivity and efficient sensor processing.

Why Choose This Part

This SoC offers a significant memory footprint with 1MB Flash and 512kB RAM, allowing for local data logging and OTA firmware updates. Its Arm Cortex-M4 core provides high-efficiency processing at 96MHz, while the 5.5dBm output power and -95.5dBm sensitivity ensure reliable wireless range in congested 2.4GHz environments.

Applications

Wearable Health Monitors
Utilizes the low-power sleep modes (61uA) and integrated FPU to process biometric sensor data while maintaining a Bluetooth LE link.
Wireless Audio Peripherals
Leverages I2S, PCM, and PDM interfaces along with Bluetooth EDR support for high-quality voice and audio streaming applications.
Smart Home Controllers
Acts as a central hub using 16 GPIOs and multiple serial interfaces (SPI, I2C, UART) to manage local sensors and actuators via Bluetooth 5.1.
HID Devices
Features dedicated HID-OFF power-saving modes for long battery life in wireless mice, keyboards, and game controllers.
