Product details
Overview
MSP430FR5730IRGER from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 4KB FRAM nonvolatile memory, 1KB SRAM, 24-MHz system clock, 6-channel 10-bit ADC, and 10-channel analog comparator. It integrates eUSCI_A0 (UART/IrDA/SPI), eUSCI_B0 (I²C/SPI), RTC with calendar, three 16-bit timers, and hardware multiplier-designed for battery-powered sensor nodes in industrial monitoring.
For engineers reviewing the MSP430FR5730IRGER datasheet, MSP430FR5730IRGER pinout, MSP430FR5730IRGER application, or MSP430FR5730IRGER equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (1.5 µA), 24-pin VQFN package footprint, and compatibility with TI's MSP-FET430U40A debug interface.
Technical Context
The MSP430FR5730IRGER implements a 16-bit CPUXV2 core with seven low-power modes, including LPM4.5 (0.32 µA shutdown) and LPM3.5 with external 32-kHz crystal (1.5 µA RTC operation). Its FRAM architecture enables simultaneous read/write without erase cycles and built-in ECC/MPU for data integrity.
Peripherals are tightly coupled to the DMA controller and clock domains: eUSCI modules support UART auto-baud detection and I²C multi-slave addressing; ADC10_B achieves 200 ksps at 100 µA; Timer_B0 provides three capture/compare registers for PWM generation and input capture with TB0CLK synchronization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5732IRGER | 8 KB FRAM, 12-channel ADC, 16-channel comparator - identical 24-pin VQFN package and pinout. | Supports higher-channel-count analog systems (e.g., multi-sensor environmental stations) without PCB redesign. | Select when future FRAM capacity or ADC channel expansion is required; software-compatible with MSP430FR5730IRGER. |
| MSP430FR2355TRHBR | 16 KB FRAM, 12-bit SAR ADC, enhanced analog front-end (PGA, DAC), but 32-pin VQFN package. | Targets precision analog applications requiring PGA gain control and DAC-based sensor excitation - not pin-compatible. | Choose for higher-resolution measurements or integrated analog signal chain; requires board layout revision. |
Compared with MSP430FR5732IRGER, the MSP430FR5730IRGER offers lower FRAM density and fewer ADC/comparator channels in the same footprint-ideal for cost-sensitive, single-sensor nodes. Versus MSP430FR2355TRHBR, it trades analog precision and FRAM size for smaller package and proven field reliability in metering-class deployments.

FAQ
What is the maximum operating frequency of the MSP430FR5730IRGER?
The MSP430FR5730IRGER supports a maximum system clock frequency of 24 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This frequency enables real-time processing of sensor data while maintaining ultra-low active-mode current consumption of 81.4 µA/MHz, making it suitable for high-throughput edge analytics in power-constrained devices.
Does the MSP430FR5730IRGER include hardware encryption or secure boot features?
No, the MSP430FR5730IRGER does not integrate hardware cryptographic accelerators or secure boot circuitry. It relies on software-based security implementations and external secure elements for authentication or encrypted firmware updates. Its Memory Protection Unit (MPU) provides basic code/data isolation but lacks AES/SHA acceleration or tamper detection found in later MSP430FR series variants.
How many ADC channels are available on the MSP430FR5730IRGER, and what is their resolution?
The MSP430FR5730IRGER features a 10-bit ADC (ADC10_B) with six external analog input channels (A0–A5) plus two internal channels (temperature sensor and VREF). It operates at up to 200 ksps with 100 µA typical supply current, supporting simultaneous sampling and hardware-controlled conversions triggered by timers or GPIO events.
What debug interface does the MSP430FR5730IRGER support, and is JTAG available?
The MSP430FR5730IRGER supports Spy-Bi-Wire (SBW) debug interface using the RST/NMI/SBWTDIO and TEST/SBWTCK pins - a two-wire subset of JTAG. Full 4-wire JTAG is not supported on this device; SBW enables programming, breakpoint setting, and real-time register inspection with TI's MSP-FET430U40A debugger and Code Composer Studio IDE.
Can the MSP430FR5730IRGER operate from a 1.8-V supply?
No, the MSP430FR5730IRGER has a specified minimum supply voltage of 2.0 V per its recommended operating conditions. Operation below 2.0 V may result in undefined behavior, including FRAM write failures, clock instability, or peripheral malfunction. For sub-2-V applications, consider the MSP430FR2xx or MSP430FR4xx families with extended low-voltage operation down to 1.8 V.
