Product details
Overview
MSP430FR5972IRGCR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, 16-MHz DCO clock, AES-256 encryption coprocessor, and integrated 12-bit ADC with 8 external channels. It operates from 1.8 V to 3.6 V and delivers 0.35 µA RTC current in LPM3.5 mode-ideal for battery-powered metering and energy-harvested sensor nodes.
For engineers reviewing the MSP430FR5972IRGCR datasheet, MSP430FR5972IRGCR pinout, MSP430FR5972IRGCR application, or MSP430FR5972IRGCR equivalent, key selection criteria include FRAM endurance (1015 write cycles), real-time clock with calendar/alarm, capacitive touch I/O without external components, and dual eUSCI modules supporting UART/IrDA/SPI/I²C at up to 10 Mbps.
Technical Context
The MSP430FR5972IRGCR implements a CPUXV2 core with 16 general-purpose registers and executes instructions in single-cycle mode at up to 16 MHz. Its memory subsystem unifies 64KB FRAM for code, data, and storage-enabling instant writes without erase latency and eliminating flash wear-out concerns.
Peripherals include three 16-bit timers (TA0–TA3, TB0) with up to seven capture/compare registers, dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) modules, 32-bit hardware multiplier, and three-channel DMA-supporting autonomous low-power operation while maintaining full peripheral concurrency.

FAQ
What is the maximum operating frequency of the MSP430FR5972IRGCR?
The MSP430FR5972IRGCR supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. This frequency is achievable across the full 1.8 V–3.6 V supply range and enables high-throughput data acquisition and processing while maintaining ultra-low-power operation in active mode (≈100 µA/MHz).
Does the MSP430FR5972IRGCR support hardware-accelerated cryptography?
Yes, the MSP430FR5972IRGCR integrates a dedicated 256-bit AES security coprocessor that performs encryption and decryption independently of the CPU. This allows secure firmware updates, encrypted data logging, and authenticated communication without compromising real-time performance or increasing power consumption.
How many I/O pins does the MSP430FR5972IRGCR provide, and what is their functional capability?
The MSP430FR5972IRGCR provides 51 programmable I/O pins in its VQFN-64 package. All pins support capacitive touch sensing without external components, configurable pullup/pulldown, edge-selectable wakeup from low-power modes, and bit-/byte-/word-wise access-enabling flexible interface design for sensors, displays, and communication peripherals.
What is the FRAM endurance specification for the MSP430FR5972IRGCR?
The MSP430FR5972IRGCR features 64KB of FRAM rated for 1015 write cycles per memory location-orders of magnitude higher than flash-based MCUs. This enables continuous data logging (e.g., sensor readings every second) for over 30,000 years without memory wear-out, making it ideal for mission-critical long-lifetime applications.
Can the MSP430FR5972IRGCR operate from a single 3.0-V coin cell battery?
Yes, the MSP430FR5972IRGCR operates reliably from 1.8 V to 3.6 V, fully covering the discharge curve of standard 3.0-V coin cells (e.g., CR2032). Its LPM3.5 mode draws only 0.35 µA with RTC active, enabling multi-year operation without voltage regulation-critical for sealed, maintenance-free deployments.
