Product details
Overview
MSP430FR5922IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 8 external channels, RTC with calendar/alarm, and dual eUSCI modules (UART/IrDA/SPI + I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and data loggers requiring long-term retention without write endurance limits.
For engineers reviewing the MSP430FR5922IPM datasheet, MSP430FR5922IPM pinout, MSP430FR5922IPM application, or MSP430FR5922IPM equivalent, key selection criteria include its LPM3.5 RTC current (0.35 µA), FRAM write speed (125 ns/word), AES256 encryption coprocessor, capacitive touch I/O support, and absence of HFXT oscillator-making it distinct from MSP430FR597x variants.
Technical Context
The MSP430FR5922IPM implements the CPUXV2 16-bit RISC core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA). Its clock system integrates DCO with 10 factory-trimmed frequencies, VLO, and LFXT only-no HFXT support per device-specific functional block diagram.
Peripherals include three 16-bit Timer_A modules (TA0–TA2), one 16-bit Timer_B (TB0) with six capture/compare registers, 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, and dual eUSCI_A/B modules supporting UART, SPI, IrDA, and I²C-all accessible via multiplexed I/O pins on the 64-pin LQFP package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5972IPM | Includes HFXT oscillator support; adds HFXIN/HFXOUT pins; same FRAM/RAM/peripherals but higher frequency capability | Suitable for systems requiring >16-MHz operation or external high-frequency crystal timing | Select when design needs HFXT-based clock sources or higher sustained CPU throughput |
| MSP430FR5922IRGC | Identical electrical specs and feature set; differs only in VQFN-64 (9 mm × 9 mm) package with thermal pad | Better thermal performance and smaller footprint; requires different PCB layout and reflow profile | Select for space-constrained designs where thermal management justifies VQFN assembly complexity |
Compared with MSP430FR5972IPM, the MSP430FR5922IPM omits HFXT support-reducing pin count and simplifying crystal circuitry-while matching FRAM endurance, security, and ultra-low-power RTC performance. Against MSP430FR5922IRGC, it offers identical functionality in LQFP-64 for easier prototyping and legacy board compatibility.

FAQ
What is the maximum operating frequency of the MSP430FR5922IPM?
The MSP430FR5922IPM supports a maximum CPU clock frequency of 16 MHz using its internally trimmed DCO oscillator. It does not include HFXT oscillator circuitry-unlike MSP430FR597x variants-so external high-frequency crystals (e.g., 4–24 MHz) cannot be used. The device relies on DCO, VLO, and LFXT (32 kHz) for all clock sources.
Does the MSP430FR5922IPM support hardware AES encryption?
Yes, the MSP430FR5922IPM includes a dedicated AES256 encryption/decryption coprocessor. This hardware engine accelerates cryptographic operations without burdening the CPU, enabling secure firmware updates, encrypted data logging in FRAM, and authentication protocols in resource-constrained IoT endpoints.
How many I/O pins does the MSP430FR5922IPM provide, and what are their key capabilities?
The MSP430FR5922IPM provides 51 programmable I/O pins in its LQFP-64 package. All pins support capacitive touch sensing without external components, edge-selectable wake-up from low-power modes, and configurable pullup/pulldown resistors. Each pin is multiplexed with timer, eUSCI, ADC, or RTC functions as documented in the pin attributes table.
What is the FRAM endurance specification for the MSP430FR5922IPM?
The MSP430FR5922IPM features 64KB of FRAM with 10¹⁵ write cycle endurance-effectively unlimited for all practical embedded applications. Unlike flash memory, FRAM requires no erase step before writing, supports byte-level writes, and retains data for 10+ years at 85°C without degradation.
Is the MSP430FR5922IPM pin-compatible with other devices in the MSP430FR59xx family?
The MSP430FR5922IPM shares the same 64-pin LQFP (PM) package footprint and pinout with MSP430FR5972IPM and MSP430FR5872IPM, but functional differences exist-most critically, the absence of HFXIN/HFXOUT pins and HFXT support in the MSP430FR5922IPM. Direct replacement requires verification of clock source requirements and peripheral mapping.
