What sets it apart from the bulk of the MSP430 family is the program memory type: 32 KB of FRAM (ferroelectric RAM) instead of conventional Flash or EEPROM.
The part brings 33 I/O lines, a 14-channel 12-bit ADC, and serial connectivity covering I²C, SPI, UART, and IrDA.
No last-time-buy notice or phase-out has been issued.
Within the MSP430FR5947 family, the base product number MSP430FR5947 covers multiple density and peripheral options. Pin-compatible siblings exist across the FRAM series with different memory sizes — check the TI cross-reference tool for the exact memory and peripheral match for your firmware image.
The listing shows Tape & Reel (TR) as the shipping medium. Tray availability would depend on the specific distributor's stock rotation; the standard TI reel quantity for this 40-VQFN package is typically 2500 units per reel.
