Overview
MSP430FR2475TPTR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32KB program FRAM, 512B information FRAM, 6KB RAM, a 12-bit SAR ADC with 12 channels, one enhanced comparator, and dual eUSCI_A (UART/SPI) and eUSCI_B (SPI/I²C) interfaces - deployed in battery-powered industrial sensors and medical wearables.
For engineers reviewing the MSP430FR2475TPTR datasheet, MSP430FR2475TPTR pinout, MSP430FR2475TPTR application, or MSP430FR2475TPTR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (660 nA), 43 GPIOs with interrupt capability, 1.8–3.6 V operation, and LQFP-48 package compatibility.
Technical Context
The MSP430FR2475TPTR integrates a digitally controlled oscillator (DCO) with FLL for ±1% accuracy at room temperature, supported by on-chip REFO (32 kHz), VLO (10 kHz), MODOSC, and external LFXT crystal interface. Its clock system delivers MCLK up to 16 MHz and configurable SMCLK prescaling (1/2/4/8).
It implements four Timer_A modules (each with three capture/compare registers) and one Timer_B7 (seven CCRs), enabling precise PWM, input capture, and RTC counter functions. The unified FRAM memory architecture supports simultaneous code execution and data logging without erase cycles.

The MSP430FR2475TPTR integrates a 12-bit SAR ADC with up to 12 input channels and a maximum sampling rate of 200 ksps. The ADC supports programmable sample-and-hold timing and internal reference voltages (1.5 V, 2.0 V, or 2.5 V), making it suitable for multi-sensor analog acquisition in compact embedded systems.
What debug interface does the MSP430FR2475TPTR use?
The MSP430FR2475TPTR uses the Spy-Bi-Wire (SBW) interface via RST/NMI/SBWTDIO and TEST/SBWTCK pins - a two-wire variant of JTAG that enables full programming, debugging, and boundary-scan functionality with minimal PCB footprint and no dedicated debug header required.
Is the MSP430FR2475TPTR pin-compatible with other devices in the MSP430FR247x family?
Yes, the MSP430FR2475TPTR in the LQFP-48 (PT) package is pin-compatible with the MSP430FR2476TPTR, sharing identical pin assignments, electrical characteristics, and peripheral mappings - enabling seamless migration between memory variants without PCB redesign.
