FRAM memory — what it changes for the firmware engineer
The MSP430FR5986IPM has 48 KB of FRAM program memory. The 2 KB SRAM is shared by stack, heap, and DMA buffers.
Peripheral set includes a 12-channel 12-bit ADC, I²C, SPI, UART, IrDA, PWM, and a brown-out reset.
Lifecycle — last-time-buy window open
The lifecycle stage is flagged as EOL hot, meaning TI has announced end-of-life and a last-time-buy window is active. If this part is on your BOM, secure the remaining lifetime volume now or plan a pin-compatible migration. The base product number is MSP430FR5986, and the 64-LQFP footprint is shared across several FRAM density options, so a drop-in replacement within the family may be possible — verify the exact memory map and peripheral set against the target variant.
