The 32 KB FRAM replaces both Flash and EEPROM in a single memory block. For designs that currently split a Flash MCU plus an external serial EEPROM, this part consolidates the BOM — no separate EEPROM, no page-write delays. The 4K x 8 RAM handles stack and variable storage; the FRAM handles persistent data and code equally.
PWM outputs support simple motor or LED drive without a dedicated timer peripheral.
The MSP430FR2355TPTR is a 16-bit MCU with a 24 MHz CPU, 32 KB FRAM program memory, 4K x 8 RAM, 44 I/O, a 12-channel 12-bit ADC, a 4-channel 12-bit DAC, and operates from 1.8 V to 3.6 V over -40°C to 105°C.
The difference is packaging: MSP430FR2355TPTR is supplied in Tape & Reel, while MSP430FR2355TR is supplied in Tray. The die, memory, and electrical specifications are identical.
