NXP MCX L14x and MCX L25x ultra-low-power Cortex-M33 MCUs target energy harvesting and battery-powered devices

MCX L series chip

NXP Semiconductors has launched the MCX L series of ultra-low-power Arm Cortex-M33 MCUs with the MCX L14x and MCX L25x SKUs. The new series offers similar peripherals as the rest of the MCX portfolio but uses a new “power management architecture that supports always-on, battery-powered applications” The MCX L series uses a dual domain architecture, with “real-time processing and ultra-low-power sensing functions in a single device.” The Arm Cortex-M33 core supports real-time processing functions while the Arm Cortex-M0+ core offers always-on operation in the ultra-low-power sense domain. The new microcontrollers reportedly use three times less power than their predecessors. The ultra-low-power series is targeted at energy-constrained applications, powered by a battery, ultracapacitor, or power harvesting circuit. These include building control, industrial sensing, smoke and fire alarms, flow meters, smart appliances, and motion detectors. NXP MCX L14x and L25x specifications: CPU Main core: Arm Cortex-M33 microcontroller @ up to 96 MHz […]

ZigEasy GEX is a series of ZigBee 3 & DigiMesh coordinators powered by the XBee 3 and XBee SX 868 modules

ZigEasy GEX Zigbee DigiMesh coordinators

The ZigEasy GEX series is a lineup of Zigbee / DigiMesh coordinators and Ethernet gateways based on Digi International’s XBee 3 and XBee SX 868 modules. These devices connect a ZigBee or DigiMesh network to a local Ethernet network or the internet. This makes it easier to create a robust Zigbee/DigiMesh network that can send and receive data from servers. The GEX2400 and GEX2400S devices integrate the Digi XBee3 module which supports Zigbee, 802.15.4, DigiMesh, and BLE and is configured directly with the XCTU software (USB or TCP/IP). The Digi SX 868 module on the GEX868 and GEX868S coordinators only supports DigiMesh. The “S” models include TLS 1.2 and AES-256 encryption for secure internet communication and are ideal for use cases that require internet access. These ZigEasy GEX Zigbee / DigiMesh coordinators can be used in mesh networks for smart homes, monitoring weather conditions, and tracking agricultural data. They can […]
