TI drives down microcontroller cost to 25 cents for IoT sensors

By Nick Flaherty at

25 functions for 25 cents with new MSP430 microcontroller for sensor designs in the Internet of Things (IoT)

Texas Instruments (TI) has launched a low cost, low power low power microcontroller for sensing applications. Developers can now implement simple sensing solutions through a variety of integrated mixed-signal features in this family of MSP430 value line sensing MCUs, available for as low as US$0.25 in high volumes.

Additions to the family include two new entry-level devices and a new TI LaunchPad development kit for quick and easy evaluation.

Developers now have the flexibility to customise 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.

The common core architecture, tools and software ecosystem and extensive documentation including migration guides make it easy for developers to choose the appropriate MSP430 device for their design.

Designers can also scale from the 0.5-KB MSP430FR2000 MCU to the rest of the MSP430 sensing and measurement portfolio for applications that require up to 256 KB of memory, higher performance or more analogue peripherals.

The MSP430FR2000 and MSP430FR2100 MCUs (with 0.5 KB and 1 KB of memory, respectively) and the new development kit join the MSP430 value line sensing family which includes the MSP430FR2111, MSP430FR2311, MSP430FR2033, MSP430FR2433 and MSP430FR4133 microcontroller families and their related development tools and software.

The MSP430FR2433 LaunchPad development kit (MSP-EXP430FR2433) is available from the TI store and distributors for US$9.99, although it is available now for $4.30.
