Product details
Overview
MSP430FR5722IRGER from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller designed for battery-operated sensing and system management. It integrates 8KB FRAM, 1KB RAM, a 10-bit ADC with 12 external channels, a 16-channel comparator, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 2 V to 3.6 V across –40°C to 85°C and targets energy-constrained sensor nodes in industrial monitoring.
For engineers reviewing the MSP430FR5722IRGER datasheet, MSP430FR5722IRGER pinout, MSP430FR5722IRGER application, or MSP430FR5722IRGER equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), RTC-enabled LPM3.5 current (1.5 µA), 24-pin VQFN package footprint, and compatibility with TI's MSP-FET430U40A debug interface.
Technical Context
The MSP430FR5722IRGER implements the MSP430 CPUXV2 core with hardware multiplier and three-channel DMA, enabling efficient signal processing in low-power modes. Its memory subsystem uses ferroelectric RAM for simultaneous read/write, ECC protection, and MPU-based access control - eliminating flash erase delays and wear-out concerns.
Peripherals include two independent 16-bit Timer_A modules (3 capture/compare registers each), one 16-bit Timer_B (3 registers), RTC with calendar/alarm, and dual eUSCI interfaces: eUSCI_A0/A1 support UART/IrDA/SPI, while eUSCI_B0 supports I²C and SPI - all configurable without CPU intervention via USCI registers.

FAQ
What is the maximum operating frequency of the MSP430FR5722IRGER?
The MSP430FR5722IRGER supports a maximum system clock frequency of 8 MHz via its digitally controlled oscillator (DCO), which offers six factory-trimmed frequency settings. This enables deterministic real-time execution for time-critical sensor sampling and control loops while maintaining ultra-low-power operation across all active and low-power modes.
Does the MSP430FR5722IRGER include hardware error correction for FRAM?
Yes, the MSP430FR5722IRGER integrates built-in Error Correction Coding (ECC) for its 8KB FRAM. This hardware-level ECC detects and corrects single-bit errors and detects double-bit errors in real time - ensuring data integrity for mission-critical logging and firmware storage without software overhead or external components.
Can the MSP430FR5722IRGER operate from a single 2.0-V supply?
Yes, the MSP430FR5722IRGER is fully specified to operate across a supply voltage range of 2.0 V to 3.6 V. At 2.0 V, it maintains full functionality including 8-MHz DCO operation, ADC conversion, RTC timing, and FRAM read/write - making it ideal for single-cell lithium primary or rechargeable battery systems.
How many eUSCI modules does the MSP430FR5722IRGER support?
The MSP430FR5722IRGER supports three eUSCI modules: eUSCI_A0 and eUSCI_A1 (each configurable for UART, IrDA, or SPI), and eUSCI_B0 (configurable for I²C or SPI). This enables concurrent communication with multiple peripherals - for example, UART for debug, SPI for an RF transceiver, and I²C for environmental sensors - without CPU arbitration.
Is the MSP430FR5722IRGER pin-compatible with other devices in the MSP430FR57xx family?
Yes, the MSP430FR5722IRGER in the RGE (VQFN-24) package shares identical pinout and electrical characteristics with MSP430FR5720IRGER, MSP430FR5724IRGER, and MSP430FR5728IRGER - enabling direct substitution within the same package variant for memory or peripheral scaling without PCB redesign.
