The added parts will, TI says, simplify industrial gateway designs, making use of full code compatibility across the SimpleLink MCU platform, which is now a single hardware, software and tool platform for wired and wireless MCUs. MSP432 Ethernet MCUs are based on a 120-MHz Arm Cortex-M4F core with an integrated MAC and PHY, together with USB, Controller Area Network (CAN) and advanced cryptography accelerators, with the designation MSP432E411Y.
Designers can combine wired communications 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).The same code base can be employed when designing end nodes and intelligent gateways.
Wireless sensor networks built on SimpleLink wireless MCUs can connect up to 50 secure sensor nodes to a gateway. The gateway, based on the SimpleLink Ethernet MSP432E4 MCUs, acts as a centralized management console to process and aggregate data and deliver it to the cloud via Ethernet for additional data analysis, visualization and storage.
For example, a heating, ventilation and air conditioning (HVAC) system can use 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 (air-flow valves) 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.
The chip comes with its own development starter kit; the MSP432E401Y MCU LaunchPad development kit is priced at $19.99. The device itself is $9.00 (1000).
