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 10-channel 10-bit ADC captures analog sensor signals directly, reducing external component count.
Includes brown-out detect and power-on reset.
The MSP430FR4131IPMR operates from 1.8 V to 3.6 V, covering single-cell battery and 3.3 V regulated supplies.
Yes, it integrates a segment LCD driver supporting up to 320 segments, eliminating the need for an external display controller.
The MSP430FR4131IPMR is manufactured as RoHS-compliant and lead-free, per TI's standard green packaging policy.
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.
