MCX W23 Bluetooth Low Energy Power Consumption Analysis
Power consumption analysis for the MCX W23 Bluetooth LE SoC, detailing measurement procedures and low-power modes for MCXW23_EVK_BB and MCXW236B_RDM boards.
Overview
This application note provides a detailed analysis of the power consumption for the NXP MCX W23 Bluetooth Low Energy (LE) system-on-chip. It outlines procedures for measuring current consumption using the MCXW23_EVK_BB evaluation kit and MCXW236B_RDM reference design board. The document describes system operation cycles and various low-power states for the CM33 MCU core and radio transceiver, including Sleep, Deep-sleep, and Power-down modes. Additionally, it examines Bluetooth LE advertising and connection events, and details power supply configurations such as High-voltage supply mode (HV_SM) and External regulated supply mode (XR_SM) to support battery-operated IoT and body-worn device designs.
Use Cases
- Optimizing battery life in IoT and wearable devices
