Product details
Overview
MSP430FR5722IPWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 8 KB FRAM nonvolatile memory, 1 KB RAM, and a 10-bit ADC with 12 external channels. It operates across 2 V–3.6 V supply and –40°C to 85°C, supporting real-time clock (RTC), three eUSCI modules (UART/I²C/SPI), and five 16-bit timers. It targets battery-powered sensor nodes in industrial monitoring systems.
For engineers reviewing the MSP430FR5722IPWR datasheet, MSP430FR5722IPWR pinout, MSP430FR5722IPWR application, or MSP430FR5722IPWR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (1.5 µA), 24-pin TSSOP package compatibility, and absence of integrated DAC or USB interface.
Technical Context
The MSP430FR5722IPWR implements the MSP430 CPUXV2 core with 16-bit RISC architecture and supports up to 8-MHz system clock via DCO, LFXT, or VLO sources. Its memory subsystem integrates 8 KB FRAM with built-in ECC and MPU, enabling unified program/data/storage use without flash erase delays.
Analog peripherals include a 10-bit ADC capable of 200 ksps at 100 µA, a 16-channel comparator with programmable hysteresis and internal reference, and dedicated voltage reference generation (VeREF±). Digital features include three-channel DMA, hardware multiplier, CRC engine, and RTC with calendar/alarm functions.

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 |
|---|---|---|---|
| MSP430FR5724IPWR | 16 KB FRAM, 6 external ADC channels, 17 I/O pins - same 28-pin TSSOP package and peripheral set. | Higher FRAM capacity suits firmware-over-the-air (FOTA) updates; reduced ADC channel count limits multi-sensor designs. | Select when firmware size exceeds 8 KB or field-upgradable code storage is required. |
| MSP430FR5720IPWR | 4 KB FRAM, 6 external ADC channels, 17 I/O pins - identical package and low-power profile but halved memory. | Lower memory restricts complex state machines or extended data buffers; suitable for cost-sensitive, function-limited nodes. | Select for minimal-feature sensor endpoints where 4 KB FRAM suffices and BOM cost is primary constraint. |
Compared with MSP430FR5722IPWR, MSP430FR5724IPWR offers double FRAM for FOTA resilience without layout change, while MSP430FR5720IPWR reduces memory and cost for fixed-function deployments - all share identical power behavior, pinout, and toolchain support.

FAQ
What is the maximum system clock frequency supported by the MSP430FR5722IPWR?
The MSP430FR5722IPWR supports a maximum system clock frequency of 8 MHz, achievable via its factory-trimmed DCO oscillator or external HFXT crystal. This frequency enables real-time processing of sensor data and communication protocol handling while maintaining ultra-low active-mode current of 81.4 µA/MHz - a key advantage for battery-operated devices where computational throughput must be balanced against energy budget.
Does the MSP430FR5722IPWR include a hardware real-time clock (RTC)?
Yes, the MSP430FR5722IPWR integrates a full-featured RTC_B module with calendar, alarm, and calibration functions. When operating in LPM3.5 with a 32-kHz crystal on PJ.4/PJ.5, it consumes only 1.5 µA (typical), making it ideal for time-critical applications like utility metering or scheduled sensor wake-up. The RTCCLK output on P1.0 further enables synchronization of external peripherals without additional timing components.
How many analog input channels does the MSP430FR5722IPWR ADC support?
The MSP430FR5722IPWR features a 10-bit ADC10_B module with support for 6 external analog input channels (A0–A5) and 2 internal references (VeREF±), as confirmed in the device comparison table and signal descriptions. This configuration is consistent across all 28-pin PW-package variants including MSP430FR5722IPWR - distinguishing it from higher-channel variants like MSP430FR5725 (12 external channels) in larger packages.
What debug interface does the MSP430FR5722IPWR use?
The MSP430FR5722IPWR uses the two-wire Spy-Bi-Wire (SBW) interface via RST/NMI/SBWTDIO and TEST/SBWTCK pins - eliminating the need for a full 4-pin JTAG connector. This reduces PCB footprint and simplifies programming during production and field updates. SBW is fully supported by TI's MSP-FET430U40A debugger and Code Composer Studio IDE, ensuring seamless development and firmware validation for the MSP430FR5722IPWR.
Is the MSP430FR5722IPWR pin-compatible with other devices in the FR572x family?
Yes, the MSP430FR5722IPWR in the 28-pin TSSOP (PW) package shares identical pinout and electrical characteristics with MSP430FR5720IPWR and MSP430FR5724IPWR - all three are fully pin-compatible. This allows direct substitution within the same PCB layout when scaling FRAM capacity (4 KB → 8 KB → 16 KB) without redesign, provided peripheral usage remains within the shared I/O and ADC channel count of the PW package variant.
