Product details
Overview
MSP430FR6922IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC, LCD driver (116 segments), and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered utility meters and portable medical devices.
For engineers reviewing the MSP430FR6922IPM datasheet, MSP430FR6922IPM pinout, MSP430FR6922IPM application, or MSP430FR6922IPM equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), RTC with calendar mode in LPM3.5 (0.35 µA), AES256 encryption support, and 64-pin LQFP package compatibility with capacitive touch I/O on all ports.
Technical Context
The MSP430FR6922IPM implements the CPUXV2 core with 16 general-purpose registers and integrates a 32-bit hardware multiplier, three-channel DMA, and CRC16/CRC32 accelerators. Its clock system includes DCO (10 factory-trimmed frequencies), VLO, and LFXT (32-kHz crystal) - but excludes HFXT, confirming absence of high-frequency crystal support per device family documentation.
It features two eUSCI_A modules (UART/IrDA/SPI up to 10 Mbps) and two eUSCI_B modules (I²C/multi-slave addressing/SPI), alongside five 16-bit timers (TA0–TA3, TB0) with capture/compare capability. The RTC domain powers LPM3.5 operation and supports calendar/alarm functions with external 3.7-pF crystal timing.

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 |
|---|---|---|---|
| MSP430FR69221IPM | I²C-based bootloader (BSL); identical FRAM, peripherals, and package. | Suitable where I²C host programming is preferred over UART; no change in runtime functionality. | Select when production programming infrastructure uses I²C rather than UART. |
| MSP430FR6972IPM | Adds HFXT support and 51 I/O pins (vs. 52); same FRAM, RTC, and AES256. | Better suited for systems requiring high-speed crystal timing (e.g., precise UART baud generation) or additional GPIO. | Choose if HFXT-driven clock stability or extra I/O is required; otherwise MSP430FR6922IPM offers optimal cost/power balance. |
Compared with MSP430FR69221IPM, the MSP430FR6922IPM provides UART BSL for simpler field updates; versus MSP430FR6972IPM, it omits HFXT to reduce external component count and PCB area - ideal for cost-sensitive, crystal-constrained metering designs.
