Product details
Overview
MSP430FR5870IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 32KB nonvolatile memory, 2KB RAM, and integrated peripherals including dual eUSCI modules (UART/IrDA/SPI + I²C/SPI), 12-bit ADC with 8 external channels, RTC with calendar, and five 16-bit timers. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and metering applications.
For engineers reviewing the MSP430FR5870IPMR datasheet, MSP430FR5870IPMR pinout, MSP430FR5870IPMR application, or MSP430FR5870IPMR equivalent, key selection criteria include its LPM3.5 current of 0.35 µA (RTC active), FRAM endurance (10¹⁵ write cycles), absence of AES encryption, and 64-pin LQFP package with 51 GPIOs - critical for low-power embedded design validation and BOM optimization.
Technical Context
The MSP430FR5870IPMR implements the CPUXV2 16-bit RISC core with up to 16-MHz operation, paired with a flexible clock system comprising DCO, LFXT (32-kHz crystal), and HFXT. Its power management supports seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA typical).
Peripherals include three-channel DMA, 32-bit hardware multiplier, CRC16/CRC32 engines, capacitive touch I/O on all pins, and dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) modules - all mapped to a 64-pin LQFP with full pin multiplexing support and Schmitt-trigger inputs on all GPIOs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5872IPMR | 64 KB FRAM (vs. 32 KB), same peripherals and package - no AES engine | Higher data logging capacity required; identical power profile and pinout | Select when extended nonvolatile storage is needed without AES security overhead |
| MSP430FR5970IPMR | 32 KB FRAM, 2 KB RAM, includes AES256 coprocessor - same LQFP-64 package | Requires secure firmware update or encrypted sensor data transmission | Choose when cryptographic acceleration justifies marginal cost increase over MSP430FR5870IPMR |
Compared with MSP430FR5870IPMR, the MSP430FR5872IPMR doubles FRAM for longer logging intervals without changing PCB layout, while the MSP430FR5970IPMR adds AES256 for secure edge processing - both retain identical low-power behavior and peripheral set except encryption capability.

FAQ
Does the MSP430FR5870IPMR include hardware AES encryption?
No, the MSP430FR5870IPMR does not implement AES encryption. Unlike the MSP430FR59xx series, this device omits the 128/256-bit AES coprocessor. The MSP430FR5870IPMR datasheet explicitly states that AES256 is not implemented in MSP430FR587x devices. For secure firmware or data handling, external crypto ICs or software-based AES must be used with the MSP430FR5870IPMR.
What is the maximum operating frequency of the MSP430FR5870IPMR CPU?
The MSP430FR5870IPMR CPUXV2 core operates at up to 16 MHz, supported by its factory-trimmed DCO and optional HFXT crystal oscillator. This frequency is achievable across the full 1.8 V–3.6 V supply range per TI SLASE66C specifications. Higher frequencies require stable HFXT input and proper decoupling; active-mode current scales linearly (~100 µA/MHz typical).
How many GPIO pins does the MSP430FR5870IPMR provide in its LQFP-64 package?
The MSP430FR5870IPMR provides 51 general-purpose I/O pins in its 64-pin LQFP package. This count excludes dedicated power (DVCC/DVSS/AVCC/AVSS), crystal (LFXIN/LFXOUT), debug (SBWTCK/SBWTDIO), and reset (RST/NMI) pins. All 51 GPIOs support capacitive touch sensing, programmable pullup/pulldown, and edge-selectable wakeup from low-power modes.
Is the MSP430FR5870IPMR pin-compatible with the MSP430FR5970IPMR?
Yes, the MSP430FR5870IPMR and MSP430FR5970IPMR share identical 64-pin LQFP (PM) packaging, pinout, and peripheral mapping - including identical signal names and functions on each pin. The only functional difference is the presence of the AES256 coprocessor in the MSP430FR5970IPMR; all other peripherals, memory sizes, and power characteristics align precisely between the two devices.
What RTC accuracy can be achieved using the internal 32-kHz crystal oscillator with the MSP430FR5870IPMR?
When using an external 32.768-kHz crystal connected to PJ.4 (LFXIN) and PJ.5 (LFXOUT), the MSP430FR5870IPMR RTC achieves ±20 ppm accuracy over –40°C to 85°C, assuming proper PCB layout and 12.5 pF load capacitance per TI design recommendations. The RTC is clocked directly by this crystal; no internal RC oscillator is used for calendar functions - ensuring long-term timekeeping stability without calibration drift.
