Product details
Overview
MSP430FR6872IPMR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, 12-bit ADC with 8 external channels, integrated LCD driver (112 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 sensor management systems.
For engineers reviewing the MSP430FR6872IPMR datasheet, MSP430FR6872IPMR pinout, MSP430FR6872IPMR application, or MSP430FR6872IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA), 64-pin LQFP package compatibility, and absence of AES encryption-distinguishing it from MSP430FR69xx variants.
Technical Context
The MSP430FR6872IPMR implements a 16-bit CPUXV2 core with up to 16-MHz DCO clock, HFXT/LFXT crystal support, and seven low-power modes including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA). Its FRAM architecture enables unified program/data/storage space with 125 ns per-word writes.
Peripherals include three 16-bit Timer_A instances (3/3/2 capture/compare registers), one 16-bit Timer_B (2/5 registers), 32-bit hardware multiplier, three-channel DMA, and dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) modules-all operating without AES256 coprocessor support per device family documentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR68721IPMR | Identical FRAM/RAM/peripherals but features I²C-based BSL instead of UART BSL; no functional difference in runtime operation. | Suitable where factory programming uses I²C infrastructure; same LPM3.5 current and LCD capabilities as MSP430FR6872IPMR. | Select MSP430FR68721IPMR only if I²C BSL aligns with production programming workflow; otherwise prefer MSP430FR6872IPMR for UART-based field updates. |
| MSP430FR6972IPMR | Includes 128/256-bit AES encryption coprocessor and supports high-frequency crystal (HFXT); MSP430FR6872IPMR lacks AES and HFXT. | Required for applications needing secure firmware updates or cryptographic data protection; not suitable for cost-sensitive metering without security mandates. | Choose MSP430FR6972IPMR when AES-256 or HFXT-driven timing accuracy is mandatory; MSP430FR6872IPMR remains optimal for basic metering with lower BOM cost. |
Compared with MSP430FR68721IPMR, the MSP430FR6872IPMR offers UART BSL for simpler field firmware updates; versus MSP430FR6972IPMR, it omits AES and HFXT to reduce cost and power in non-security-critical utility applications.

FAQ
Does the MSP430FR6872IPMR include hardware AES encryption?
No, the MSP430FR6872IPMR does not include AES encryption. Per TI's device comparison tables and functional block diagram notes, AES256 is implemented only in MSP430FR69xx devices-not in MSP430FR687x or MSP430FR682x families. The MSP430FR6872IPMR retains all other peripherals including 64KB FRAM, 12-bit ADC, and LCD_C driver, but excludes the security coprocessor to reduce cost and power in non-security applications.
What is the maximum operating frequency of the MSP430FR6872IPMR?
The MSP430FR6872IPMR supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. It also accepts external high-frequency crystals (HFXT) and 32.768-kHz low-frequency crystals (LFXT) for precise timing. The DCO's 10 selectable frequencies allow flexible clock configuration without external components, while maintaining ultra-low-power operation across all modes.
Which package type does the MSP430FR6872IPMR use, and what are its thermal considerations?
The MSP430FR6872IPMR uses a 64-pin LQFP package (10 mm × 10 mm) with part suffix "IPMR". TI recommends connecting the exposed thermal pad to DVSS (ground) to ensure proper heat dissipation and stable operation under continuous active-mode conditions. This connection improves thermal resistance and supports reliable long-term operation in enclosed metering housings.
How many LCD segments can the MSP430FR6872IPMR drive, and what mux configurations are supported?
The MSP430FR6872IPMR integrates the LCD_C peripheral capable of driving up to 112 segments in static, 2-mux, 3-mux, or 4-mux configurations. Segment assignments are mapped to dedicated pins (e.g., P6.3–P6.6 for COM0–COM3) and support programmable contrast control via internal charge pump. This eliminates need for external LCD drivers in thermostats and portable medical displays.
What low-power modes are available on the MSP430FR6872IPMR, and what is the lowest achievable current draw?
The MSP430FR6872IPMR supports seven low-power modes, including LPM3.5 (RTC active at 0.35 µA typical) and LPM4.5 (full shutdown at 0.04 µA typical). These modes leverage FRAM's instant-on capability and optimized power gating to extend battery life in utility meters and portable sensors far beyond flash-based MCUs-enabling multi-year operation on a single CR2032 cell.
