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. Internal oscillator eliminates crystal in many applications.
Not qualified for under-hood automotive or downhole environments — those would need an AEC-Q100 graded device.
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.
The CPU core runs at 25 MHz maximum.
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.
