Texas Instruments is aiming at sensing and measurement with two low-power additions to its non-volatile FRAM MSP430 microcontroller family.

MSP430FR5994 microcontrollers have 256kbyte of FRAM and DSP capability from the firm’s low energy accelerator (LEA) which computes fast Fourier transforms (FFTs), finite impulse response (FIR) filters, infinite impulse response (IIR) filters and other maths functions.

“The LEA module provides a DSP library with support for more than 50 math functions and a plug-and-play design that allows developers to un-box our MSP430FR5994 LaunchPad development kit and start processing complex math algorithms in less than five minutes,” said the firm.

MSP430FR2111 MCUs are ‘value’ processors intended for up-grading 8bit designs and come in a 3×3 mm QFN.

“Even the most cost conscious developer now has a solution that integrates a 10bit ADC, EEPROM functionality, comparator, real-time clock, timers, internal oscillator and 16-bit MCU,” said TI. “With up to 50 times the RAM of comparable 8bit MCUs thanks to unified memory, developers will no longer need to program in assembly.”

50 times?  – devices have 1kbyte of RAM, and 3.75kbyt or 2kbyte of FRAM, in a 16pin: TSSOP or 24pin QFN.

It sees customers moving from existing MSP430G2x devices to MSP430FR2x thanks to the common core, tool ecosystem and migration guides.
