Product details

Key features for the design

The MSP430F5514IRGCR: 25 MHz core handles sensor polling and protocol framing. 64 KB Flash holds firmware and USB stack; 6 KB RAM supports small packet buffers. On-chip brown-out detect, POR, DMA, PWM, and WDT reduce external components. Internal oscillator eliminates crystal in many applications.

Temperature grade and environment

Rated for -40°C to 85°C ambient, this MCU suits outdoor enclosures, unheated factory floors, and telecom cabinets. Not qualified for under-hood automotive or downhole environments — those would need an AEC-Q100 graded device. The 1.8 V to 3.6 V supply range lets it run from two alkaline cells or a single Li-ion battery without a regulator.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430F5514IRGCR?

The MSP430F5514IRGCR is part of the MSP430F5xx family; devices with the same 64-VQFN footprint and USB peripheral (e.g., MSP430F5519) share the pinout and can be used as a drop-in alternate with different Flash or RAM sizes. Check the TI cross-reference for exact memory matching.

What is MSP430F5514IRGCR's listed speed?

The CPU core runs at 25 MHz maximum.

What compliance documentation does this part have?

Texas Instruments provides RoHS and REACH compliance declarations for the MSP430F5514IRGCR. The part is lead-free and the 64-VQFN package is compatible with lead-free reflow profiles.
