Product details
Overview
MSP430FR6872IRGCR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, 12-bit ADC (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 nodes.
For engineers reviewing the MSP430FR6872IRGCR datasheet, MSP430FR6872IRGCR pinout, MSP430FR6872IRGCR application, or MSP430FR6872IRGCR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), RTC in LPM3.5 (0.35 µA), capacitive touch I/O without external components, and absence of AES encryption-distinguishing it from MSP430FR69xx variants.
Technical Context
The MSP430FR6872IRGCR 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, LFXT (32 kHz crystal), and HFXT (up to 16 MHz), but excludes HFXIN/HFXOUT per device family documentation.
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, CRC16/CRC32 engines, and dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) modules-configured for UART BSL operation on P2.0/P2.1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR6872IPMR | LQFP-64 package (10 mm × 10 mm); identical electrical specs and peripheral set | Preferred for through-hole prototyping or legacy PCB layouts requiring larger pitch | Select when thermal management allows larger footprint or when hand-soldering is required |
| MSP430FR6870IRGCR | 32KB FRAM (vs. 64KB); otherwise identical pinout, peripherals, and power profile | Suitable for cost-sensitive designs with smaller firmware and data logging requirements | Choose when application firmware fits within 32KB and BOM cost reduction is critical |
Compared with MSP430FR6872IPMR, the MSP430FR6872IRGCR offers identical functionality in a smaller VQFN package for higher-density layouts; versus MSP430FR6870IRGCR, it doubles FRAM capacity for extended data buffering-critical in utility meter firmware updates and historical logging.

FAQ
Does the MSP430FR6872IRGCR include AES encryption hardware?
No, the MSP430FR6872IRGCR does not include AES encryption. Per the functional block diagram note in the datasheet, AES256 is implemented only in MSP430FR69xx devices-not in MSP430FR687x or MSP430FR682x families. The MSP430FR6872IRGCR relies on software-based security or external crypto elements if encryption is required.
What crystal specifications are required for the RTC on the MSP430FR6872IRGCR?
The MSP430FR6872IRGCR RTC requires a 32-kHz tuning-fork crystal with a 3.7-pF load capacitance, connected to PJ.4 (LFXIN) and PJ.5 (LFXOUT). This configuration enables calendar-mode operation in LPM3.5 at 0.35 µA typical current draw, as specified in the device overview section of the SLASE23E datasheet.
Is the MSP430FR6872IRGCR pin-compatible with the MSP430FR6972IRGCR?
Yes, the MSP430FR6872IRGCR and MSP430FR6972IRGCR share identical VQFN-64 (RGC) pinouts and package dimensions. However, the MSP430FR6972IRGCR adds AES256 hardware and supports UART BSL only-while the MSP430FR6872IRGCR omits AES and also supports UART BSL. Functionally, they are drop-in replacements except where AES or specific BSL protocol is required.
How many I/O pins does the MSP430FR6872IRGCR support, and which ports are available?
The MSP430FR6872IRGCR provides 51 programmable I/O pins across ports P1–P7, P9, PJ, and additional dedicated pins (e.g., TEST, RST/NMI). All I/O pins support capacitive touch sensing without external components, and each port supports bit-, byte-, and word-wise access with configurable pullup/pulldown resistors and edge-selectable LPM wakeup.
What is the maximum operating frequency of the MSP430FR6872IRGCR, and how is it achieved?
The MSP430FR6872IRGCR operates up to 16 MHz using its integrated digitally controlled oscillator (DCO) with 10 factory-trimmed frequencies, or via external HFXT (high-frequency crystal) up to 16 MHz. The DCO eliminates need for external high-speed crystals in most applications, while HFXT enables precise timing-critical functions like high-speed SPI or UART at full rate.
