Product details
Overview
MSP430FR6922IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, integrated 12-bit ADC with 8 external channels, 116-segment LCD driver, AES-256 encryption coprocessor, and RTC with calendar/alarm - designed for battery-powered utility meters, thermostats, and portable medical devices.
For engineers reviewing the MSP430FR6922IPMR datasheet, MSP430FR6922IPMR pinout, MSP430FR6922IPMR application, or MSP430FR6922IPMR equivalent, key selection criteria include LPM3.5 current (0.35 µA), FRAM endurance (1015 write cycles), 32-kHz LFXT support, capacitive touch I/O without external components, and UART/I²C/SPI dual eUSCI modules.
Technical Context
The MSP430FR6922IPMR implements a 16-bit CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA). Its clock system integrates DCO, VLO, and LFXT (32 kHz crystal), but excludes HFXT - confirmed by functional block diagram notes and device comparison tables.
Peripherals include three eUSCI_A (UART/IrDA/SPI) and two eUSCI_B (I²C/SPI) modules, five 16-bit timers (TA0–TA3, TB0), 32-bit hardware multiplier, CRC16/CRC32, and a dedicated LCD_C module supporting static/2–4 mux configurations up to 116 segments - all mapped to 64-pin LQFP package pins per Section 4.1 pin diagrams.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit CPUXV2, up to 16-MHz operation - enables deterministic real-time control in resource-constrained embedded systems. |
| Nonvolatile Memory | 64KB FRAM with 125 ns/word write speed and 1015 endurance - eliminates flash wear-out concerns and enables frequent data logging. |
| Low-Power Modes | LPM3.5 draws 0.35 µA (RTC active); LPM4.5 draws 0.04 µA - extends battery life to >10 years in metering applications. |
| Analog Peripherals | 12-bit ADC with internal reference, sample-and-hold, and 8 external inputs - supports precision sensor interfacing without external signal conditioning. |
| Security | AES-256 encryption/decryption coprocessor with true random number seed - meets firmware integrity and secure communication requirements in smart meters. |
| Display Support | Integrated 116-segment LCD driver with contrast control - reduces BOM cost and PCB area for human-interface displays. |
| Communication | eUSCI_A0/A1 (UART/IrDA/SPI) + eUSCI_B0/B1 (I²C/SPI) - enables dual-protocol connectivity for sensor networks and host interfaces. |
Pinout & Package
LQFP-64 package (10 mm × 10 mm), thermally enhanced with exposed pad (not electrically connected per TI mechanical data). Pin functions validated against Figure 4-1 and Table 4-1 of SLASE23E Rev. August 2018.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0 / P1.1 / P1.2 / P1.3 | ADC input / VREF+/− / TA0/TA1 timer I/O / Capacitive touch | Supports simultaneous analog sensing, reference voltage generation, and touch button implementation on same port. |
| P2.0–P2.3 | UCA0TXD/RXD/CLK/STE (eUSCI_A0) | Dedicated UART interface with automatic baud-rate detection - simplifies host communication setup in field-deployed meters. |
| P3.4–P3.7 | UCA1TXD/RXD/CLK/STE (eUSCI_A1) | Second independent UART channel - enables dual-interface designs (e.g., IR + RS-485 or BLE bridge). |
| P5.4–P5.7 | UCA1TXD/RXD/CLK/STE (alternate mapping) | Flexible pin remapping allows routing optimization when primary UCA1 pins conflict with LCD or timer signals. |
| P6.3–P6.6 | COM0–COM3 (LCD common outputs) | Drives up to 4 multiplexed LCD backplanes - essential for segment-based display in thermostats and cost allocators. |
| PJ.4 / PJ.5 | LFXIN / LFXOUT | Connects to 32-kHz crystal for RTC accuracy ±20 ppm - required for time-of-use billing in electricity meters. |
Key Features
| Feature | Design Value |
|---|---|
| Ferroelectric RAM (FRAM) | 64KB unified memory space enabling atomic writes, zero-wear endurance, and instant nonvolatile storage - critical for tamper-proof metering logs. |
| Capacitive Touch I/O | All GPIO pins support CSD without external components - reduces bill-of-materials and enables robust front-panel controls in harsh environments. |
| Real-Time Clock (RTC) | Calendar mode with alarm, powered in LPM3.5 at 0.35 µA - maintains accurate timekeeping during multi-year battery operation. |
| Hardware AES-256 | Dedicated coprocessor offloads encryption from CPU, preserving low-power operation while securing firmware updates and data transmission. |
| Three-Channel DMA | Enables autonomous peripheral-to-memory transfers (e.g., ADC → FRAM) without CPU wake-up - minimizes active-mode energy consumption. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR69221IPMR | Identical FRAM/RAM/peripherals but features I²C-based bootloader (BSL) instead of UART BSL - requires different programming interface. | Suitable where I²C programming infrastructure exists; not drop-in compatible for UART-based production programming. | Select MSP430FR69221IPMR only if I²C BSL aligns with factory programming workflow and no UART debug interface is needed post-deployment. |
| MSP430FR6920IPMR | 32KB FRAM (vs. 64KB), otherwise identical peripheral set, package, and power specs - direct pin-compatible variant. | Appropriate for cost-sensitive designs with lower firmware/data storage requirements, such as basic thermostats without extended logging. | Choose MSP430FR6920IPMR when application firmware size and data retention needs fit within 32KB FRAM - reduces component cost without layout change. |
Compared with MSP430FR69221IPMR, the MSP430FR6922IPMR offers UART BSL for universal programming compatibility; versus MSP430FR6920IPMR, it doubles FRAM capacity for advanced metering firmware and long-term interval data storage - both alternatives retain identical low-power performance and LCD capability.

FAQ
What is the maximum operating frequency of the MSP430FR6922IPMR?
The MSP430FR6922IPMR operates at up to 16 MHz using its factory-trimmed DCO or external HFXT oscillator. However, the MSP430FR6922IPMR does not implement HFXT per functional block diagram notes - so maximum reliable frequency is 16 MHz via DCO, with LFXT (32 kHz) used for RTC and low-frequency timing only.
Does the MSP430FR6922IPMR support hardware encryption?
Yes, the MSP430FR6922IPMR includes a dedicated AES-256 encryption/decryption coprocessor with true random number seed generation. This hardware accelerator enables secure firmware updates and encrypted data transmission without burdening the CPU - a verified feature documented in Section 1.1 Features of SLASE23E.
What LCD configuration does the MSP430FR6922IPMR support?
The MSP430FR6922IPMR integrates the LCD_C module supporting up to 116 segments in static, 2-, 3-, or 4-mux configurations. It drives common outputs (COM0–COM3) and segment lines via dedicated pins (e.g., P6.3–P6.6), with contrast control and charge pump - confirmed in device comparison Table 3-1 and functional block diagram.
Is the MSP430FR6922IPMR pin-compatible with other devices in the FR69xx family?
Yes, the MSP430FR6922IPMR in LQFP-64 (PM) package shares identical pinout with MSP430FR69221IPMR, MSP430FR6920IPMR, and MSP430FR69201IPMR - verified by matching pin diagrams in Figure 4-1 and consistent signal naming across Table 4-1. Functional differences (e.g., BSL type, FRAM size) do not affect physical compatibility.
What is the typical current consumption of the MSP430FR6922IPMR in RTC-only mode?
In LPM3.5 mode with RTC active and VLO disabled, the MSP430FR6922IPMR consumes 0.35 µA (typical), as specified in Section 1.1 Features. This value assumes operation with 32-kHz crystal (LFXT) and includes RTC, calendar, and alarm functionality - enabling decade-long battery life in metering applications.
