Product details
Overview
MSP430FR5972IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, and integrated peripherals including 12-bit ADC, AES256 encryption coprocessor, RTC with calendar, five 16-bit timers, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and metering systems.
For engineers reviewing the MSP430FR5972IPM datasheet, MSP430FR5972IPM pinout, MSP430FR5972IPM application, or MSP430FR5972IPM equivalent, key selection considerations include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA), AES256 security acceleration, capacitive touch I/O support, and 64-pin LQFP package compatibility with energy-harvesting and industrial sensing designs.
Technical Context
The MSP430FR5972IPM implements the CPUXV2 16-bit RISC core with 16-MHz max clock, paired with a flexible clock system featuring DCO, LFXT (32 kHz crystal), and HFXT (up to 24 MHz). Its power architecture supports seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA).
Peripherals are tightly coupled via three-channel DMA and unified FRAM addressing. The device integrates hardware CRC16/CRC32, 32-bit MPY, analog comparator (8-channel), and eUSCI_A0/A1 (UART/IrDA/SPI) plus eUSCI_B0/B1 (I²C/SPI), all accessible through multiplexed I/O pins with programmable pullup/pulldown and edge-selectable wake-up.

FAQ
What is the maximum operating frequency of the MSP430FR5972IPM?
The MSP430FR5972IPM supports a maximum CPU clock frequency of 16 MHz using the integrated DCO or external HFXT oscillator. This timing capability enables real-time signal processing and high-throughput serial communication while maintaining ultra-low active-mode current of approximately 100 µA/MHz - a key advantage for responsive yet energy-efficient embedded control.
Does the MSP430FR5972IPM support hardware-accelerated cryptography?
Yes, the MSP430FR5972IPM includes a dedicated AES256 encryption and decryption coprocessor. This hardware module executes AES rounds independently of the CPU, reducing active time by >90% versus software implementations and enabling secure firmware updates, encrypted sensor log storage, and authenticated wireless communication without compromising power budget - a capability not present in MSP430FR5969IPM.
What package type and dimensions does the MSP430FR5972IPM use?
The MSP430FR5972IPM uses a 64-pin LQFP (PM) package measuring 10 mm × 10 mm with 0.5 mm lead pitch. TI recommends connecting the exposed thermal pad to DVSS for optimal thermal performance and noise immunity. This JEDEC-standard footprint ensures compatibility with mainstream PCB assembly processes and thermal management practices in industrial and metering applications.
How does the FRAM memory in the MSP430FR5972IPM differ from traditional flash memory?
The MSP430FR5972IPM's 64KB FRAM offers 10¹⁵ write cycles (vs. ~10⁵ for flash), 125 ns write time per word (no erase required), and true read/write concurrency. Unlike flash, FRAM requires no page erase before write, eliminates wear-leveling firmware overhead, and retains data without power - making it ideal for high-frequency data logging, firmware patching, and fail-safe parameter storage in mission-critical edge devices.
Can the MSP430FR5972IPM operate from a single 1.8-V supply?
Yes, the MSP430FR5972IPM operates across a wide supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including 16-MHz DCO operation, FRAM read/write, ADC conversion, and peripheral operation - subject to SVS level constraints. This enables direct integration with single-cell Li-ion, Li-SOCl₂, or energy-harvesting sources without intermediate regulation, simplifying power architecture and improving system efficiency.
