Multi-Channel Continuous Glucose Monitoring (CGM) Solutions
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
NXP's Continuous Glucose Monitoring (CGM) reference solution helps healthcare companies and partners build compact, accurate and power-efficient patient monitoring devices. It combines an ultra-low-power (ULP) multichannel electrochemical analog front-end (AFE)—including the MCX W23 Bluetooth® Low Energy (LE) microcontroller (MCU)—for precise sensing, secure connectivity and long battery life.
The AFE enables Near Field Communication (NFC) for easy activation, pairing, programming and data readout, while Bluetooth LE ensures stable real-time data streaming. The platform's tiny wearable form factor, long shelf and wear life, and included reference software and companion app are designed to accelerate development and speed CGM innovation.
The solution has been fully developed, validated and tested. Additionally, NXP provides all the materials needed to customize the design, including schematics, a bill of materials (BOM), firmware, an application note, a technical training video, a user guide and a Getting Started guide. Enablement is available for NDA-approved customers.
Enablement is available to non-disclosure agreement (NDA)-approved customers. Reach out to your local NXP representatives to know more about this solution and request for access.
