Product details
Overview
MSP430FR5962IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 128KB+0.5KB FRAM, 8KB RAM, 16-channel 12-bit ADC, 16-input analog comparator, and dual 32-bit CRC engines. It operates from 1.8 V to 3.6 V and supports LPM3.5 standby at 350 nA (RTC active). It targets battery-powered sensing nodes in industrial infrastructure and wearable electronics.
For engineers reviewing the MSP430FR5962IPMR datasheet, MSP430FR5962IPMR pinout, MSP430FR5962IPMR application, or MSP430FR5962IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), absence of LEA accelerator (vs. FR599x), UART/I²C bootloader support, 64-pin LQFP package, and real-time clock with calendar mode.
Technical Context
The MSP430FR5962IPMR implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz. Its memory subsystem integrates 128KB FRAM for code/data storage and 8KB SRAM, with no low-energy accelerator (LEA) - distinguishing it from the FR599x series. The device uses a flexible clock system with DCO, LFXT (32 kHz crystal), and HFXT (up to 24 MHz).
Peripherals include six 16-bit timers (TA0–TA4, TB0), four eUSCI_A modules (UART/IrDA/SPI), four eUSCI_B modules (I²C/SPI), AES-128/256 encryption coprocessor, and capacitive-touch I/O on all pins. It lacks LEA but retains full DMA (6 channels), RTC with alarm/calendar, and MPY32 hardware multiplier.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5964IPMR | 256KB+0.5KB FRAM (vs. 128KB), same peripherals and package - no LEA accelerator | Supports larger firmware images and extended data logging buffers; identical power profile and pinout | Select when firmware size exceeds 128KB or long-term sensor history must be retained locally |
| MSP430FR5992IPMR | 128KB+0.5KB FRAM, includes LEA subsystem (4KB shared RAM, 256-pt FFT acceleration) | Enables real-time DSP tasks (e.g., noise cancellation, gesture recognition) without CPU load; higher active current | Select when on-device signal processing (FFT/FIR) is required and 40× speedup justifies added complexity and cost |
Compared with MSP430FR5964IPMR, the MSP430FR5962IPMR trades FRAM capacity for lower unit cost and identical low-power behavior; compared with MSP430FR5992IPMR, it omits LEA to reduce die size and active-mode current, making it optimal for pure control-and-logging roles.

FAQ
What is the maximum operating frequency of the MSP430FR5962IPMR?
The MSP430FR5962IPMR supports a maximum system clock frequency of 16 MHz using its integrated digitally controlled oscillator (DCO) or external HFXT crystal. This frequency is fully supported across all operating voltage ranges (1.8 V to 3.6 V) and enables deterministic real-time execution for time-critical control loops and communication timing.
Does the MSP430FR5962IPMR include a low-energy accelerator (LEA)?
No, the MSP430FR5962IPMR does not include the low-energy accelerator (LEA) subsystem. LEA is exclusive to the MSP430FR599x family (e.g., MSP430FR5992IPMR). The MSP430FR5962IPMR retains full CPUXV2 performance, 6-channel DMA, and hardware MPY32 but relies on software-based signal processing.
What package type and pin count does the MSP430FR5962IPMR use?
The MSP430FR5962IPMR uses a 64-pin LQFP (PM) package with 10 mm × 10 mm body size and standard 0.5 mm pitch. This package is pin-compatible with other MSP430FR596x/FR599x variants in the PM footprint, enabling scalable design reuse across memory and feature tiers.
How much FRAM and RAM does the MSP430FR5962IPMR provide?
The MSP430FR5962IPMR integrates 128KB of main FRAM plus 0.5KB of information FRAM for configuration storage, and 8KB of SRAM. The FRAM serves as unified nonvolatile memory for both program code and data, supporting instant writes and 10¹⁵ endurance cycles without wear leveling.
Is the MSP430FR5962IPMR compatible with the MSP430FR5964IPMR in terms of pinout and software?
Yes, the MSP430FR5962IPMR and MSP430FR5964IPMR share identical 64-pin LQFP (PM) packages, pin assignments, register maps, and peripheral configurations. Software written for one is binary-compatible with the other; only FRAM capacity differs (128KB vs. 256KB), requiring no code changes for migration within this footprint.
