Insight into the Stellaris microcontroller family

What defines the Stellaris line of MCUs?
a. Which MCU line can be termed as the closest competitor of Stellaris?

TI has a very broad offering in its embedded processing and MCU product portfolio because TI supports a large number of customers across diverse applications spaces. We see our broad portfolio not as product lines that compete, but as product lines that complement each other. For each of our MCU product lines, there are applications and markets that those products do better than any other. For example, if it's ultra low power and absolute battery life that an application requires, the MSP430 product line is the best solution. For connectivity and human-machine interface applications, Stellaris provides the fastest time-to-market. For real-time computing needs in PLC lighting and multi-axis motion control, the C2000 product line blends computation with performance to excel.

b. What sets it apart from competing products?

Stellaris MCUs are chosen in embedded applications that feature connectivity (Ethernet MAC+PHY, USB host/device/OTG, CAN, high performance serial and M2M buses), 32bit MCU performance, and a desire for a common code base built upon the ARM architecture. Understanding that it is software that drives a design's time-to-market, Stellaris focuses on making our parts easy to use, with free license, royalty-free use StellarisWare software that provides peripheral driver libraries, USB libraries, graphics libraries, IEC 60730 support, and bootloaders. On many Stellaris MCUs, we put StellarisWare software in ROM, which both saves flash for applications space and provides an indication of how robust StellarisWare is – it wouldn't be in ROM if it didn't work.

Which applications in India would Stellaris cater to and specifically benefit?

As a few examples, Stellaris is finding use in the following applications in India today:

 • Applications processor for smart e-metering, extending into other smart grid applications

 • Communications applications, especially quickly adding Ethernet MAC+PHY capabilities to serial-based embedded designs (see our RDK-S2E reference design, which comes with software for TCP/IP, Telnet, HTTP, FTP, DHCP, and PPP.)

 • Human-machine interface applications, especially for industrial applications (see our RDK-IDM intelligent display module reference design).

Is there anything that you would like to add about the Stellaris line?

The most exciting part of having the Stellaris line as a part of Texas Instruments is being able to work with TI's full signal chain in providing full applications solutions for our customers. We are continuing to invest in the MCU market, and you should expect to see further integration of TI's stellar analogue with our MCU products in the future.
