Merging wired and wireless connectivity?

07 January 2018

Created to make it easier for developers to connect sensors from a gateway to the cloud, Texas Instruments (TI) has introduced Ethernet connectivity to the SimpleLink microcontroller (MCU) platform, a single hardware, software and tool platform for wired and wireless MCUs.

The new SimpleLink MSP432 Ethernet MCUs are based on a 120-MHz Arm Cortex-M4F core with an integrated MAC and PHY, which helps accelerate time-to-market for grid infrastructure and industrial automation gateway applications.

The SimpleLink MCU platform is a single development environment that delivers flexible hardware, software and tool options for customers developing Internet of Things (IoT) applications. With a single software architecture, modular development kits and free software tools for every point in the design life cycle, the SimpleLink MCU ecosystem allows for code reuse across the portfolio of microcontrollers, which supports a wide range of connectivity standards and technologies (

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.
