Product details

FRAM memory: fast writes, high endurance, no battery backup

4.5 KB FRAM program memory writes at bus speed with no erase cycle.

60 I/O and serial connectivity for system integration

With 60 general-purpose I/O pins in a 64-pin LQFP package, this MCU provides enough GPIO for parallel sensor arrays, keypad matrices, and segment-drive expansion. The serial interfaces — I²C, SPI, UART, and IrDA — cover common peripheral buses for displays, radios, and external ADCs. The 10-channel 10-bit ADC captures analog sensor signals directly, reducing external component count.

Supply voltage and power management

Supply range is 1.8 V to 3.6 V. Includes brown-out detect and power-on reset.

Temperature grade and deployment environment

Rated for -40°C to 85°C ambient. 64-LQFP package.

Frequently asked questions

What is the operating voltage of MSP430FR4131IPMR?

The MSP430FR4131IPMR operates from 1.8 V to 3.6 V, covering single-cell battery and 3.3 V regulated supplies.

Does MSP430FR4131IPMR have a built-in LCD controller?

Yes, it integrates a segment LCD driver supporting up to 320 segments, eliminating the need for an external display controller.

Is MSP430FR4131IPMR RoHS compliant?

The MSP430FR4131IPMR is manufactured as RoHS-compliant and lead-free, per TI's standard green packaging policy.

What is the MSP430FR4131IPMR equivalent or alternative?

Pin-compatible alternatives within the MSP430FR4xx family, such as the MSP430FR4133 with larger FRAM, share the same 64-LQFP footprint and LCD peripheral — verify memory and peripheral differences against your firmware requirements.
