onsemi Continuous Glucose Monitoring System Solutions

Featuring the CEM102 AFE and RSL15 Bluetooth Wireless MCU

System-level innovation is reshaping the future of medical and industrial electronics. onsemi provides comprehensive microelectronic system solutions that enable manufacturers to design smarter, more efficient products with long-term reliability.

A standout example is the pairing of the CEM102 analog front end with the RSL15 Bluetooth Low Energy wireless MCU. This combination forms a compact, ultra-low power platform for electrochemical sensing and wireless communication. It is ideally suited for applications such as continuous glucose monitors (CGMs), wearable health devices, and connected IoT sensors.

The CEM102 is engineered for amperometric measurements and ultra-low current detection. When integrated with the RSL15, the result is a complete two-channel electrochemical measurement system that operates with minimal power consumption and a small footprint. The system supports a wide supply voltage range and is compatible with common battery types, including 1.5 V silver oxide and 3 V coin cells.

To accelerate development, onsemi offers an evaluation board that includes both the CEM102 and RSL15, along with sample firmware to simplify system setup and measurement routines.
