NXP KM3x Series Precision Metrology Microcontrollers (MCUs)
Based on Arm® Cortex®-M0+
With Metrology as a key component to Electric Vehicle Charging, NXP’s KM35 MCus can help:
- Enabling single-chip 1-, 2- and 3-phase metering designs
- AFE, Security and HMI. Single crystal implementation
- Single point of calibration during manufacture
- Highest accuracy metrology with regional feature support
- Multiple ƩΔ ADCs with PGA
- Supports neutral disconnect use case
- Compliance with WELMEC/OIML recommendations
- Memory and peripheral protection
- Hardware tamper detect with time stamping
- Low-power RTC, battery backup with tamper memory
The KM3x series enables high accuracy, secure 1-, 2- and 3-phase electricity metering solutions, as well as flow meter and other precision measurement applications, through powerful analog front end (AFE), rich security protection and HMI functionality.
