Just when you thought they couldn’t go any lower, bam! MCUs for 25 cents. Texas Instruments just introduced a version of its popular MSP430 line that offers “25 functions for 25 cents.”
In other words, developers have the flexibility to customize 25 common system-level functions including timers, input/output expanders, system reset controllers, electrically erasable programmable read-only memory (EEPROM) and more, using a library of code examples.
In most cases, the new part, will be used as a complementary device, mostly in sensing applications. It is likely used to handle housekeeping functions, offloading things from the main CPU. This results in a much cleaner design, with tasks segmented to the device that’s most appropriate.
With the ultra-low-cost MCU, developers can implement simple sensing solutions through a variety of integrated mixed-signal features. A new TI LaunchPad development kit is also being released that allows for quick and easy evaluation. A common core architecture, a tools and software ecosystem, and extensive documentation including migration guides simplify the integration process.
