A Flash-based MCU would impose write-cycle budgeting and slower block-erase times.
The device comes in an 87-ball NFBGA (6x6 mm). It requires a controlled reflow profile and post-reflow X-ray inspection.

The device comes in an 87-ball NFBGA (6x6 mm). It requires a controlled reflow profile and post-reflow X-ray inspection.
The supply voltage range is 1.8 V to 3.6 V on Vcc/Vdd. The device is not 5 V tolerant on I/O pins; level shifting is required for 5 V logic interfaces.
Yes — the MSP430FR5992IZVWR is available in Tape & Reel (TR) and Cut Tape (CT) options, suitable for automated pick-and-place assembly.
The CPU core runs at 16 MHz. This is the maximum clock rate for the MSP430 CPUXV2 core on this device.
