Product details
Overview
MSP430FR5722IPW 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 from 2 V to 3.6 V across –40°C to 85°C and delivers 81.4 µA/MHz active current. It targets battery-powered sensor management and data acquisition systems requiring fast FRAM writes and RTC calendar functionality.
For engineers reviewing the MSP430FR5722IPW datasheet, MSP430FR5722IPW pinout, MSP430FR5722IPW application, or MSP430FR5722IPW equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (1.5 µA), eUSCI_A0/A1 UART/IrDA/SPI support, and TSSOP-28 package compatibility with legacy MSP430 footprint constraints.
Technical Context
The MSP430FR5722IPW implements the MSP430 CPUXV2 core with FRAM-based unified memory architecture, enabling simultaneous code execution and data logging without erase delays. Its power management includes integrated LDO, SVS with reset, and zero-power brownout detection - critical for unattended remote sensing nodes.
Peripherals are tightly coupled via three-channel DMA and hardware multiplier: two eUSCI_A modules handle UART bootloading and IrDA, while eUSCI_B0 supports I²C multi-slave addressing and SPI. The 16-channel comparator and RTC with alarm operate independently in LPM3.5, sustaining real-time operation at 1.5 µA.

FAQ
What is the maximum operating frequency of the MSP430FR5722IPW?
The MSP430FR5722IPW supports a maximum system clock frequency of 8 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This frequency enables real-time processing of sensor data and communication protocols while maintaining ultra-low active-mode current consumption of 81.4 µA/MHz - a key specification confirmed in TI's SLASE35C datasheet Section 5.16.
Does the MSP430FR5722IPW support hardware UART bootloading?
Yes, the MSP430FR5722IPW includes a hardware UART bootloader (BSL) accessible via eUSCI_A0 or eUSCI_A1. This allows in-system programming without JTAG, using standard UART signals and TI's documented BSL command set. The feature is explicitly listed in the "Features" section of the SLASE35C datasheet and supported in the TSSOP-28 (PW) package configuration.
How much FRAM and RAM does the MSP430FR5722IPW contain?
The MSP430FR5722IPW integrates 8 KB of ferroelectric RAM (FRAM) for nonvolatile program, data, and storage use, plus 1 KB of volatile RAM for runtime variables and stack operations. These values are fixed for this variant and differ from other family members like the MSP430FR5728IPW (16 KB FRAM) or MSP430FR5721IPW (4 KB FRAM), as detailed in Table 3-1 of the SLASE35C datasheet.
What low-power modes are available on the MSP430FR5722IPW?
The MSP430FR5722IPW supports seven low-power modes including LPM3 (6.3 µA with VLO), LPM3.5 (1.5 µA with 32-kHz crystal RTC), and LPM4.5 (0.32 µA shutdown). These modes are enabled by its integrated power management system with SVS, BOR, and zero-power brownout detection - all verified in Sections 5.4–5.5 of the SLASE35C datasheet for the PW package.
Is the MSP430FR5722IPW pin-compatible with other devices in the FR572x family?
The MSP430FR5722IPW in TSSOP-28 (PW) package shares identical pinout and signal mapping with MSP430FR5720IPW, MSP430FR5724IPW, MSP430FR5726IPW, and MSP430FR5728IPW - as confirmed by Figure 4-4 and Table 4-1 in SLASE35C. This allows direct substitution within the same package group when FRAM size or ADC channel count permits functional equivalence.
