Product details
Overview
MSP430FR5922IPMR 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 metering systems requiring long-term data retention without write endurance limits.
For engineers reviewing the MSP430FR5922IPMR datasheet, MSP430FR5922IPMR pinout, MSP430FR5922IPMR application, or MSP430FR5922IPMR 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 - confirming design compatibility for low-frequency crystal-only timing applications.
Technical Context
The MSP430FR5922IPMR implements the MSP430 CPUXV2 core with 16 registers and integrates a flexible clock system limited to DCO and LFXT (32-kHz crystal only); HFXT is not implemented per device-specific note. Its power management supports seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown), with verified supply currents of 0.35 µA and 0.04 µA respectively.
Peripherals include three 16-bit Timer_A modules (TA0–TA3), one 16-bit Timer_B (TB0), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, and dual eUSCI_A/eUSCI_B modules - all mapped to 51 GPIO pins in the 64-pin LQFP package. The FRAM memory architecture enables unified program/data/storage space with 10¹⁵ write-cycle endurance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit CPUXV2 with 16 registers; executes instructions at up to 16 MHz - enables deterministic real-time control in resource-constrained edge nodes. |
| FRAM Capacity | 64 KB nonvolatile FRAM with unified memory space - eliminates separate flash/EEPROM partitions and supports instant writes without erase cycles. |
| ADC Resolution | 12-bit SAR ADC with internal reference and sample-and-hold; supports up to 8 external analog inputs - suitable for precision sensor signal acquisition. |
| RTC Current (LPM3.5) | 0.35 µA typical - enables multi-year battery life in always-on timekeeping applications such as utility meters and environmental loggers. |
| Low-Power Modes | 7 defined modes including LPM3.5 (RTC active) and LPM4.5 (0.04 µA shutdown) - provides granular power-state control for intermittent sensing duty cycles. |
| Crypto Engine | AES256 security coprocessor with true random number seed - accelerates secure firmware updates and encrypted data storage in IoT endpoints. |
| Capacitive Touch | All I/O pins support capacitive touch sensing without external components - reduces BOM cost and PCB area for human-interface designs. |
Pinout & Package
LQFP-64 (10 mm × 10 mm) package with exposed thermal pad (recommended connection to DVSS). Pin count: 64 total, 51 configurable GPIOs, 3 dedicated power/ground pairs (DVCC/DVSS), and 2 analog supply pins (AVCC/AVSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 |
|---|---|---|---|
| MSP430FR5972IPMR | Includes HFXT oscillator and 51 GPIOs in same LQFP-64 package; adds high-frequency crystal support for USB-capable timing. | Required where 4–25 MHz system clocks or USB PHY synchronization are needed - unsuitable for pure 32-kHz RTC-only designs. | Select when higher-speed peripherals (e.g., faster SPI, USB) are required; verify HFXT layout and crystal load capacitance. |
| MSP430FR5922IG56 | TSSOP-56 package (6.1 mm × 14 mm); identical FRAM/RAM/peripheral set but 46 GPIOs and no PJ.6/PJ.7 (HFXIN/HFXOUT) pins. | Better suited for space-constrained PCBs where 64-pin LQFP footprint is prohibitive; same LFXT-only clocking as MSP430FR5922IPMR. | Choose for compact industrial controls or portable instruments needing smaller form factor and identical low-power behavior. |
Compared with MSP430FR5972IPMR, the MSP430FR5922IPMR omits HFXT for lower cost and reduced crystal BOM, while the MSP430FR5922IG56 trades pin count for footprint reduction - both retain identical FRAM endurance, RTC performance, and AES256 capability.

FAQ
What is the maximum operating frequency of the MSP430FR5922IPMR?
The MSP430FR5922IPMR supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. It does not include an HFXT oscillator, so external high-frequency crystals (4–25 MHz) cannot be used - all timing above 32 kHz must derive from the DCO or LFXT-synchronized sources. This limitation is explicitly documented for the FR592x series in the functional block diagram notes.
Does the MSP430FR5922IPMR support hardware AES encryption?
Yes, the MSP430FR5922IPMR includes a dedicated 128/256-bit AES security coprocessor, enabling accelerated encryption and decryption of data stored in FRAM or transmitted via eUSCI interfaces. This feature is confirmed in the "Code Security and Encryption" section of the datasheet and applies specifically to the MSP430FR59xx(1) family, which includes the MSP430FR5922IPMR.
How many GPIO pins does the MSP430FR5922IPMR provide in its LQFP-64 package?
The MSP430FR5922IPMR provides 51 configurable general-purpose I/O pins in its 64-pin LQFP package. This count excludes power (DVCC/DVSS), analog supply (AVCC/AVSS), test/debug (TEST/SBWTCK/RST), and crystal (LFXIN/LFXOUT) pins. The pin attributes table confirms 51 I/O signals across ports P1–P9 and PJ, all supporting capacitive touch functionality.
What is the typical current consumption of the MSP430FR5922IPMR in RTC-active low-power mode?
The MSP430FR5922IPMR consumes 0.35 µA typical in LPM3.5 mode, where the real-time clock remains active with calendar and alarm functions enabled. This value is measured at 3 V and 25°C with the RTC clocked by a 32-kHz crystal, and is specified in the "Low-Power Mode LPMx.5 Supply Currents" section of the datasheet - a key differentiator for multi-year battery operation.
Is the MSP430FR5922IPMR pin-compatible with the MSP430FR5972IPMR?
No, the MSP430FR5922IPMR is not pin-compatible with the MSP430FR5972IPMR despite sharing the same LQFP-64 package. The FR5972 includes HFXIN/HFXOUT pins (PJ.6/PJ.7) absent in the FR5922, and their pin multiplexing differs for several peripheral functions (e.g., TB0OUTH, DMAE0). The datasheet's device comparison tables and pin diagrams confirm distinct signal mappings - PCB layout reuse is not supported.
