Product Summary

The CEM102 is an Analog Front End (AFE) product specifically developed for applications such as Continuous Glucose Monitoring (CGM) and other amperometric measurements that require the detection of very small currents.

The CEM102 is designed to be paired with ON Semiconductor's RSL15, an Arm® Cortex®-M33 processor-based Bluetooth® Low Energy 5.2 wireless SoC, and operates with the RSL15 at extremely low power consumption, extending battery life.
In addition, the power supply voltage range is wide, from 1.3 to 3.6 V, so it can operate on either a 1.5 V silver oxide battery or a single​ ​3 V coin battery.

The CEM102 also has an evaluation board, which contains the CEM102 as well as the RSL15.
It also includes example code for setting up the CEM102 and running measurements, facilitating system and firmware development.

Evaluation boards available

We offer an evaluation board that combines the RSL15, an ultra-low power Arm® Cortex®-M33 processor-based Bluetooth® Low Energy 5.2 wireless SoC.
By combining it with RSL15, low power consumption can be achieved for the entire system.
Additionally, the necessary firmware modules are already installed in the RSL15 and sample code is provided, making design easy.
