Product details
Overview
MSP430FR5720IRGER from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 4KB FRAM nonvolatile memory, 1KB RAM, and a 8-MHz CPU. It integrates a 10-bit ADC with 6 external channels, a 16-channel analog comparator, three eUSCI modules (two UART/SPI-capable, one I²C/SPI-capable), and five 16-bit timers. Designed for battery-powered sensor nodes in industrial monitoring systems.
For engineers reviewing the MSP430FR5720IRGER datasheet, MSP430FR5720IRGER pinout, MSP430FR5720IRGER application, or MSP430FR5720IRGER equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), RTC support in LPM3.5 (1.5 µA), standby current (6.3 µA in LPM3), 24-pin VQFN package footprint, and compatibility with TI's MSP-FET430U40A debug interface.
Technical Context
The MSP430FR5720IRGER implements the MSP430xV2 CPU core with unified FRAM memory architecture enabling simultaneous read/write operations and eliminating erase-before-write delays. Its power management system includes an integrated LDO, SVS with reset capability, and zero-power brownout detection - critical for unattended remote deployments.
Peripherals are tightly coupled via three-channel DMA and a 32-bit hardware multiplier. The eUSCI_A0/A1 modules support UART with automatic baud-rate detection and IrDA encoding/decoding; eUSCI_B0 supports I²C with multi-slave addressing and SPI - all configurable without CPU intervention during low-power modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5722IRGER | 8 KB FRAM, same 24-pin RGE package, identical peripheral set and pinout | Supports larger firmware images and extended data buffers without layout change | Select when firmware size exceeds 4 KB or long-term data retention beyond 4 KB is required |
| MSP430FR2476TRHBR | 16 KB FRAM, 64-pin VQFN, enhanced ADC (12-bit, 16 ch), but no RTC or comparator_D | Better suited for high-resolution analog acquisition; lacks RTC-driven low-power scheduling | Choose for higher-precision sensing where RTC and comparator functions are secondary |
Compared with MSP430FR5722IRGER, the MSP430FR5720IRGER trades FRAM capacity for cost-sensitive deployments; versus MSP430FR2476TRHBR, it prioritizes ultra-low-power timing and analog comparators over raw ADC resolution - making it optimal for time-critical, battery-limited edge nodes.

FAQ
What is the maximum operating frequency of the MSP430FR5720IRGER?
The MSP430FR5720IRGER supports a maximum system clock frequency of 8 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This speed enables deterministic real-time response for sensor sampling, filtering, and communication tasks while maintaining ultra-low active-mode current (81.4 µA/MHz typical). The MSP430FR5720IRGER's architecture sustains this performance across its full 2.0–3.6 V supply range.
Does the MSP430FR5720IRGER include a real-time clock (RTC) module?
Yes, the MSP430FR5720IRGER integrates a calendar-mode RTC_B module with alarm and calibration functions. When powered by a 32-kHz crystal connected to PJ.4/XIN and PJ.5/XOUT, it operates in LPM3.5 mode drawing only 1.5 µA - enabling precise timekeeping for scheduled wake-ups, data timestamping, and interval-based sensor polling without external RTC ICs.
How much FRAM and RAM does the MSP430FR5720IRGER provide?
The MSP430FR5720IRGER contains 4 KB of ferroelectric RAM (FRAM) for nonvolatile code and data storage, and 1 KB of volatile RAM for runtime variables and stack. Unlike flash, the FRAM supports true byte-level writes at 125 ns per word, 10¹⁵ write cycles, and zero erase latency - making the MSP430FR5720IRGER ideal for frequent data logging and firmware updates in field-deployed devices.
Which serial interfaces are supported by the MSP430FR5720IRGER?
The MSP430FR5720IRGER features three enhanced universal serial communication interfaces: eUSCI_A0 and eUSCI_A1 each support UART (with automatic baud-rate detection), IrDA, and SPI; eUSCI_B0 supports I²C (with multi-slave addressing) and SPI. All operate independently of the CPU in low-power modes, allowing background communication while the core remains in LPM3.
What is the pin count and package type of the MSP430FR5720IRGER?
The MSP430FR5720IRGER uses a 24-pin VQFN package (RGE variant), measuring 4 mm × 4 mm with 0.5 mm pitch and an exposed thermal pad. This compact footprint matches other members of the FR572x family in the RGE package - including MSP430FR5722IRGER and MSP430FR5724IRGER - enabling scalable design reuse across memory and feature variants.
