Product details
Overview
MSP430FR5872IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, and integrated peripherals including 12-bit ADC, RTC with calendar, five 16-bit timers, dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) modules, and capacitive touch I/O - deployed in battery-powered sensor nodes and energy-harvesting metering systems.
For engineers reviewing the MSP430FR5872IPMR datasheet, MSP430FR5872IPMR pinout, MSP430FR5872IPMR application, or MSP430FR5872IPMR equivalent, key selection criteria include LPM3.5 current (0.35 µA), FRAM endurance (10¹⁵ writes), 51 GPIO count, 64-pin LQFP package, and absence of AES256 encryption - critical for secure firmware updates in industrial logging devices.
Technical Context
The MSP430FR5872IPMR 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 (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT support - enabling precise timing for real-time data acquisition without external oscillators.
Peripherals are memory-mapped and DMA-accessible: three-channel DMA services ADC, UART, and timer capture/compare; CRC16/CRC32 accelerators verify data integrity; and the 12-bit ADC supports up to 8 external channels with internal reference and sample-and-hold - all operating down to 1.8 V supply.

FAQ
Does MSP430FR5872IPMR support AES encryption?
No, MSP430FR5872IPMR does not include the AES256 security coprocessor. This feature is present only in the MSP430FR597x and MSP430FR592x families. The MSP430FR5872IPMR datasheet explicitly states "AES256 is not implemented" - making it unsuitable for applications requiring hardware-accelerated encryption or secure boot verification.
What is the maximum operating frequency of MSP430FR5872IPMR?
The MSP430FR5872IPMR operates at up to 16 MHz using its digitally controlled oscillator (DCO), which offers 10 factory-trimmed frequencies. It also supports external high-frequency crystals (HFXT) up to 24 MHz, though the DCO is typically used for ultra-low-power applications due to faster startup and lower current draw.
Which crystal is required for RTC functionality on MSP430FR5872IPMR?
A 32.768-kHz crystal must be connected between PJ.4 (LFXIN) and PJ.5 (LFXOUT) to enable calendar-mode RTC operation on MSP430FR5872IPMR. The datasheet specifies this configuration for accurate timekeeping; internal VLO provides only approximate timing (±10%) and cannot support calendar functions.
How many UART interfaces does MSP430FR5872IPMR provide?
MSP430FR5872IPMR provides two independent UART channels via eUSCI_A0 and eUSCI_A1 modules. Each supports automatic baud-rate detection, IrDA encoding/decoding, and SPI mode - enabling simultaneous communication with a host PC (eUSCI_A0) and a wireless transceiver (eUSCI_A1) without software multiplexing.
Is MSP430FR5872IPMR pin-compatible with MSP430FR5972IPMR?
Yes, MSP430FR5872IPMR and MSP430FR5972IPMR share identical 64-pin LQFP (PM) packaging, pinout, and power/ground assignments. Functional differences (e.g., AES256, HFXIN/HFXOUT) do not affect physical compatibility - allowing drop-in replacement where security or HFXT features are unused.
