Product details

Overview

MSP430FR5724IRGER from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller designed for battery-operated sensor nodes and energy-constrained embedded systems. It integrates 8KB of nonvolatile FRAM, 1KB RAM, a 10-bit ADC with 6 external channels, a 16-channel comparator, and dual eUSCI modules supporting UART, SPI, and I²C - enabling compact, low-power data acquisition in industrial monitoring and smart metering applications.

For engineers reviewing the MSP430FR5724IRGER datasheet, MSP430FR5724IRGER pinout, MSP430FR5724IRGER application, or MSP430FR5724IRGER equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (1.5 µA), 24-pin VQFN package footprint, and compatibility with TI's MSP-FET430U40A debug interface.

Technical Context

The MSP430FR5724IRGER implements the MSP430 CPUXV2 core with 16-bit RISC architecture and operates at up to 8 MHz. Its memory subsystem uses ferroelectric RAM for simultaneous read/write, zero-wait-state execution, and built-in ECC - eliminating flash erase delays and wear leveling overhead in frequent logging scenarios.

Peripherals include two independent 16-bit Timer_B modules (one with three capture/compare registers), one 16-bit Timer_A (three CCRs), hardware multiplier, 3-channel DMA, and real-time clock with calendar mode - all synchronized via a flexible clock system with DCO, VLO, LFXT, and HFXT sources.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MSP430FR5728RGE	16KB FRAM, 6 external ADC channels, same 24-pin RGE package and peripheral set.	Better suited for designs requiring larger code/data space or extended analog logging capacity.	Select when firmware size exceeds 8KB or long-term data retention >10 years is required.
MSP430FR2355RSMR	16KB FRAM, 12-bit SAR ADC (8 ch), enhanced analog front-end (PGA, DAC), but no RTC_B module.	Optimized for analog-intensive applications like sensor signal conditioning, lacking calendar-mode RTC.	Choose for higher-resolution analog acquisition where RTC calendar functions are unnecessary.

Compared with MSP430FR5724IRGER, the MSP430FR5728RGE offers double FRAM capacity in identical packaging for seamless migration, while the MSP430FR2355RSMR trades RTC functionality for richer analog integration - making each alternative optimal for distinct subsystem requirements rather than drop-in replacement.
