CEL CMP53x Modules are Zigbee/Thread/BLE/NFC combo devices with integrated Arm® CortexTM-M4 MCU core. These modules have their RF performance meticulously designed and tested to maximize range in noisy and harsh environments. The CMP53x modules utilize NFC technology and reliable connectivity to reduce network provisioning and operating costs. The optimized antenna, combined with the low-power radio and MCU makes it ideal for power-restricted applications. The CMP53x modules provide 640kB of SoC-integrated program flash with an additional 8Mb of on-module flash to support OTA FW updates and data-logging. The efficient Cortex M4 processor and onboard resources enable the modules to be used as standalone end devices. Typical applications include building automation, smart energy, security systems, and sensor networks.
