The 48-LQFP (7×7 mm) package is surface-mount. Standard hot-air rework is straightforward — the exposed pad is absent, so the part lifts cleanly with preheat.
The MSP430FR2155TPT offers 32 KB FRAM and 4 K × 8 RAM, while the MSP430FR2154 typically provides 16 KB FRAM. Both share the same 48-LQFP footprint and peripheral set, making them pin-compatible density options within the family.
The MSP430FR2155TPT is rated for -40°C to 105°C, covering industrial and automotive cabin environments without active cooling.
