Making it easier for developers to connect sensors from a gateway to the cloud, Texas Instruments has introduced Ethernet connectivity to the SimpleLink microcontroller (MCU) platform. The new SimpleLink MSP432 Ethernet MCUs are based on a high-performance 120 MHz ARM Cortex-M4F core with an integrated MAC and PHY, helping accelerate time to market for grid infrastructure and industrial automation gateway applications.
Developers can reduce design time and simplify board layout with new MSP432E411Y MCUs, which integrate an Ethernet MAC and PHY, USB, Controller Area Network (CAN) and advanced cryptography accelerators. Wired communications can be combined with the SimpleLink MSP432 host MCUs through integrated serial interfaces with wireless connectivity technology such as sub-1 GHz, Wi-Fi and Bluetooth to connect end nodes to the cloud using the SimpleLink software development kit (SDK).
Designers can create a wireless sensor network using SimpleLink wireless MCUs by connecting as many as 50 secure sensor nodes to a gateway. The gateway, based on the SimpleLink Ethernet MSP432E4 MCUs, acts as a centralised management console to process and aggregate data and deliver it to the cloud via Ethernet for additional data analysis, visualisation and storage. Companies developing these types of gateways can interface with existing wired installations while adding the latest wireless connectivity technologies.
For example, a heating, ventilation and air conditioning (HVAC) system can leverage other SimpleLink MCUs such as the sub-1 GHz CC1310 wireless MCU and MSP432P4 host MCU to form a network of air quality sensors and wired dampers to connect to an Ethernet-enabled HVAC system controller and then to the cloud. Users can then access real-time data to monitor and manage their energy profile.
