Product details
Overview
MSP430FR5722IRGET from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 8 KB FRAM nonvolatile memory, 1 KB RAM, and a 16-channel analog comparator. It operates from 2 V to 3.6 V across –40°C to 85°C and delivers 8-MHz system clock performance. It targets battery-powered sensor management and data acquisition systems requiring fast FRAM writes (125 ns/word) and sub-µA real-time clock operation.
For engineers reviewing the MSP430FR5722IRGET datasheet, MSP430FR5722IRGET pinout, MSP430FR5722IRGET application, or MSP430FR5722IRGET equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), integrated RTC with calendar/alarm, dual eUSCI modules supporting UART/I²C/SPI, and low-power modes down to 0.32 µA in LPM4.5 shutdown.
Technical Context
The MSP430FR5722IRGET implements the MSP430 CPUXV2 core with hardware multiplier and three-channel DMA, enabling efficient signal processing in energy-constrained environments. Its FRAM architecture replaces both flash and SRAM, allowing unified memory access for code, data, and logging without erase cycles.
It integrates two enhanced universal serial communication interfaces (eUSCI_A0/A1 for UART/IrDA/SPI; eUSCI_B0 for I²C/SPI), a 10-bit 200-ksps ADC with internal reference, and five 16-bit timers-including Timer_A (2×3-CC) and Timer_B (1×3-CC)-supporting precise timing and PWM generation in sensor node wake-up and measurement sequences.

FAQ
What is the maximum operating frequency of the MSP430FR5722IRGET?
The MSP430FR5722IRGET supports a maximum system clock frequency of 8 MHz, achieved via its factory-trimmed DCO or external HFXT crystal. This frequency is fully operational across the entire recommended voltage range (2.0 V to 3.6 V) and temperature range (–40°C to 85°C), enabling deterministic real-time response in time-critical sensor sampling and control loops.
Does the MSP430FR5722IRGET include an integrated voltage reference for the ADC?
Yes, the MSP430FR5722IRGET includes an internal voltage reference generator supporting the 10-bit ADC. Pins P1.1 (VeREF+) and P1.0 (VeREF−) provide programmable reference inputs, enabling ratiometric measurements with external sensors. The internal reference eliminates the need for external precision voltage sources in most low-power sensing applications.
How many serial communication interfaces does the MSP430FR5722IRGET support?
The MSP430FR5722IRGET integrates three enhanced universal serial communication interfaces: eUSCI_A0 and eUSCI_A1 each support UART, IrDA, and SPI; eUSCI_B0 supports I²C and SPI. This configuration allows concurrent communication with multiple peripherals-for example, UART telemetry to a gateway, I²C sensor reads, and SPI flash logging-all without CPU intervention.
What low-power modes are available on the MSP430FR5722IRGET, and what is the lowest current draw?
The MSP430FR5722IRGET offers seven low-power modes (LPM0–LPM4.5). The deepest mode is LPM4.5 (shutdown), drawing just 0.32 µA typical with RAM retention. In LPM3.5 with RTC active and 32-kHz crystal, current drops to 1.5 µA-ideal for time-triggered wake-up in battery-powered data loggers and environmental monitors.
Is the MSP430FR5722IRGET pin-compatible with other devices in the MSP430FR57xx family?
Yes, the MSP430FR5722IRGET in the RGE-24 package shares identical pinout and electrical characteristics with MSP430FR5720IRGET, MSP430FR5724IRGET, and MSP430FR5728IRGET. This enables scalable design reuse-firmware and PCB layouts can be shared across variants differing only in FRAM size (4 KB, 8 KB, or 16 KB) and ADC channel count.
