Product details
Overview
MSP430FR5922IG56R 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 supports LPM3.5 standby at 0.35 µA - optimized for battery-powered sensor nodes and energy-harvested IoT endpoints.
For engineers reviewing the MSP430FR5922IG56R datasheet, MSP430FR5922IG56R pinout, MSP430FR5922IG56R application, or MSP430FR5922IG56R equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), integrated capacitive touch I/O without external components, AES256 security coprocessor, and TSSOP-56 package compatibility with space-constrained industrial sensing designs.
Technical Context
The MSP430FR5922IG56R implements the MSP430xV2 CPU core with unified FRAM memory architecture enabling simultaneous code execution and data write operations. Its clock system integrates DCO, LFXT (32-kHz crystal), and VLO - but excludes HFXT, distinguishing it from FR597x variants.
Peripherals include three 16-bit Timer_A instances (TA0–TA2) and one Timer_B (TB0) with capture/compare, 32-bit hardware multiplier, 3-channel DMA, CRC16/CRC32 engines, and dual eUSCI_A/B modules supporting UART, SPI, IrDA, and I²C - all operating under seven low-power modes including LPM4.5 (0.04 µA shutdown).

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 |
|---|---|---|---|
| MSP430FR5922IPW | TSSOP-56 vs. TSSOP-56 - identical pinout and electrical specs; differs only in tape-and-reel packaging (R suffix denotes reel). | No functional difference; selected when automated SMT placement requires carrier tape format. | Direct drop-in replacement for volume production; same thermal and electrical behavior. |
| MSP430FR5972IPMR | 64KB FRAM, 2KB RAM, but adds HFXT support and 64-pin LQFP package; lacks AES256 in some revisions. | Required for designs needing high-frequency crystal timing or more GPIOs; not suitable where TSSOP-56 footprint is fixed. | Choose only if HFXT or additional I/O is mandatory; otherwise MSP430FR5922IG56R offers better power efficiency and smaller footprint. |
Compared with MSP430FR5922IPW, the MSP430FR5922IG56R shares identical functionality and pinout but is optimized for high-volume tape-and-reel assembly; versus MSP430FR5972IPMR, it trades HFXT capability for lower static current and reduced package size - ideal for space- and energy-constrained edge nodes.

FAQ
What is the maximum operating frequency of the MSP430FR5922IG56R?
The MSP430FR5922IG56R supports up to 16 MHz system clock via its factory-trimmed DCO oscillator. It does not include HFXT circuitry, so high-frequency crystal operation is not supported - unlike MSP430FR597x variants. The DCO provides stable timing across voltage and temperature for real-time control tasks without external crystal cost or board space.
Does the MSP430FR5922IG56R include hardware AES encryption?
Yes, the MSP430FR5922IG56R integrates a dedicated 128/256-bit AES security coprocessor. This hardware engine accelerates encryption/decryption independently of the CPU, enabling secure firmware updates and protected data storage without compromising real-time performance - confirmed in the SLASE66C datasheet Section 1.1.
What package type and dimensions does the MSP430FR5922IG56R use?
The MSP430FR5922IG56R uses a 56-pin TSSOP (DGG) package measuring 6.1 mm × 14 mm with 0.5 mm pitch. This compact surface-mount outline is specified in TI's Package Option Addendum and matches the pinout shown in Figure 4-3 of the SLASE66C datasheet for MSP430FR592x devices.
How many ADC input channels does the MSP430FR5922IG56R support?
The MSP430FR5922IG56R features a 12-bit ADC12_B module supporting up to 8 external analog input channels (A0–A7), plus internal references and temperature sensor. Channel mapping is configurable via ADCCTL1 and ADCMCTL0 registers, and all inputs are accessible through P1.x pins per the device-specific signal descriptions.
Is the MSP430FR5922IG56R pin-compatible with other MSP430FR592x variants?
Yes, the MSP430FR5922IG56R shares identical pinout and signal mapping with all MSP430FR592x devices in the TSSOP-56 (DGG) package, including MSP430FR59221IG56R. Pin attributes, multiplexing, and reset defaults are consistent across this variant group - verified in Table 4-1 and Figure 4-3 of the SLASE66C datasheet.
