Product details
Overview
MSP430FR5962IPNR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 128KB + 0.5KB FRAM, 8KB RAM, 16-channel 12-bit ADC, and dual 16-bit timers (TA0/TA1 with 3+3 capture/compare registers). It operates from 1.8 V to 3.6 V and supports UART/I²C via four eUSCI_A and four eUSCI_B modules - used in battery-powered grid infrastructure monitoring and industrial sensor nodes.
For engineers reviewing the MSP430FR5962IPNR datasheet, MSP430FR5962IPNR pinout, MSP430FR5962IPNR application, or MSP430FR5962IPNR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (350 nA), 68 I/O count, absence of LEA accelerator, and LQFP-80 package compatibility with existing MSP430FR59xx layouts.
Technical Context
The MSP430FR5962IPNR implements a CPUXV2 16-bit RISC core with up to 16 MHz clocking, DCO/LFXT/HFXT clock sources, and hardware AES-128/256 encryption. Its memory subsystem integrates unified FRAM (nonvolatile, fast write) and SRAM, managed by FRCTL_A and MPU with IP encapsulation.
It features six 16-bit timers (TA0–TA4, TB0), 32-/16-bit CRC, 6-channel DMA, RTC with calendar/alarm, and capacitive-touch I/O on all pins - but excludes the Low-Energy Accelerator (LEA), distinguishing it from MSP430FR599x variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5964IPNR | 256KB + 0.5KB FRAM, same peripherals and package - no LEA accelerator. | Higher firmware/data storage capacity required for OTA updates or extended logging. | Select when >128KB code space or long-term data retention beyond 10 years is needed. |
| MSP430FR5992IPNR | 128KB + 0.5KB FRAM + Low-Energy Accelerator (LEA) - adds 4KB shared RAM and FFT acceleration. | Real-time DSP tasks (e.g., vibration analysis, ECG feature extraction) demand hardware-accelerated math. | Choose only if LEA's 40× FFT speedup justifies higher cost and power in compute-intensive edge analytics. |
Compared with MSP430FR5964IPNR, the MSP430FR5962IPNR trades 128KB FRAM capacity for identical low-power performance and peripheral set; versus MSP430FR5992IPNR, it omits LEA to reduce cost and static power while retaining full sensor interface capability.

FAQ
What is the maximum operating frequency of the MSP430FR5962IPNR?
The MSP430FR5962IPNR supports a maximum CPU clock frequency of 16 MHz using its 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 of metrology and control algorithms without timing violations.
Does the MSP430FR5962IPNR include a Low-Energy Accelerator (LEA)?
No, the MSP430FR5962IPNR does not include the Low-Energy Accelerator. LEA is exclusive to the MSP430FR599x series (e.g., MSP430FR5992IPNR). The MSP430FR5962IPNR retains full peripheral and memory functionality but omits LEA to optimize cost and static power for applications not requiring hardware-accelerated DSP.
How many I²C interfaces does the MSP430FR5962IPNR support?
The MSP430FR5962IPNR supports four eUSCI_B modules, each configurable as an I²C master or slave interface. These operate independently with separate address spaces and clock domains, enabling concurrent communication with up to four I²C sensor clusters or peripheral ICs without software arbitration.
What is the standby current consumption of the MSP430FR5962IPNR with RTC active?
In LPM3.5 mode with the real-time clock running from a 3.7-pF crystal, the MSP430FR5962IPNR consumes 350 nA typical current. This value is measured at 3 V and 25°C and includes RTC oscillator, calendar logic, and RAM retention - enabling decade-long operation on a single CR2032 cell.
Is the MSP430FR5962IPNR pin-compatible with other MSP430FR59xx LQFP-80 variants?
Yes, the MSP430FR5962IPNR shares identical pinout, electrical characteristics, and package dimensions with MSP430FR5964IPNR, MSP430FR5992IPNR, and MSP430FR5994IPNR in the LQFP-80 (PN) package. Firmware and PCB layout are interchangeable across these variants, allowing design reuse and migration based on FRAM size or LEA requirements.
