Product details
Overview
MSP430FR5962IZVWR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 128KB+0.5KB FRAM, 8KB RAM, 16-channel 12-bit ADC, 16-channel 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 with RTC. Used in battery-powered grid infrastructure and building automation nodes requiring nonvolatile memory endurance and deterministic low-power operation.
For engineers reviewing the MSP430FR5962IZVWR datasheet, MSP430FR5962IZVWR pinout, MSP430FR5962IZVWR application, or MSP430FR5962IZVWR equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LEA absence (vs. FR599x), UART/I²C bootloader support, 87-pin NFBGA package constraints, and real-time clock operation with 3.7-pF crystal.
Technical Context
This device belongs to the MSP430FR596x family and implements a 16-bit CPUXV2 core with 16 registers, fixed-frequency DCO plus LFXT/HFXT crystal support, and six 16-bit timers (including Timer_A with up to three capture/compare registers and Timer_B with two instantiations). It lacks the Low-Energy Accelerator (LEA) subsystem present in FR599x variants.
The memory architecture integrates 128KB FRAM for program/data storage and 8KB SRAM, with hardware AES-128/256 encryption, IP encapsulation, and MPU-based memory protection. Peripheral set includes four eUSCI_A (UART/IrDA/SPI) and four eUSCI_B (I²C/SPI) modules, RTC with calendar/alarm, and capacitive-touch I/O on all pins without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5964IZVWR | 256KB+0.5KB FRAM (vs. 128KB), same peripherals and package | Preferred where larger firmware image or extended data logging capacity is required | Select when application firmware exceeds 128KB or requires long-term historical sensor storage |

FAQ
Does MSP430FR5962IZVWR support hardware AES encryption?
Yes, MSP430FR5962IZVWR includes a dedicated AES-128/256 coprocessor that performs encryption and decryption independently of the CPU. This enables secure boot validation, encrypted OTA firmware updates, and protected communication channels without consuming CPU cycles or increasing active-mode power consumption. The MSP430FR5962IZVWR AES engine supports ECB, CBC, and CTR modes per NIST SP 800-38A.
What is the minimum supply voltage for MSP430FR5962IZVWR in active mode?
The minimum supply voltage for MSP430FR5962IZVWR in active mode is 1.8 V, constrained by the SVS (Supply Voltage Supervisor) trip point. Operation below 1.8 V may cause unpredictable behavior or brownout resets. The device supports full functionality-including FRAM writes, ADC conversions, and crypto operations-across the 1.8 V to 3.6 V range, with current draw scaling linearly with voltage and frequency.
Is MSP430FR5962IZVWR pin-compatible with MSP430FR5994IZVWR?
No, MSP430FR5962IZVWR is not pin-compatible with MSP430FR5994IZVWR despite sharing the ZVW package. While both use the 87-pin NFBGA, their pin functions differ significantly-for example, MSP430FR5994IZVWR allocates pins to the LEA subsystem and additional DMA channels, whereas MSP430FR5962IZVWR repurposes those balls for standard peripherals. PCB layout must be verified against each device's specific signal mapping in Section 7 of the SLASE54D datasheet.
Can MSP430FR5962IZVWR operate with a 3.7-pF RTC crystal?
Yes, MSP430FR5962IZVWR supports RTC operation with a 3.7-pF tuning-fork crystal in LPM3.5 mode, drawing only 350 nA. This configuration requires proper PCB layout per TI's crystal guidelines-short traces, ground guard ring, and no nearby digital switching noise sources. The crystal connects to PJ.4 (LFXIN) and PJ.5 (LFXOUT), and the RTC_C module automatically configures low-drive mode for optimal stability and current efficiency.
Does MSP430FR5962IZVWR include a Low-Energy Accelerator (LEA)?
No, MSP430FR5962IZVWR does not include the Low-Energy Accelerator (LEA) subsystem. LEA is exclusive to the MSP430FR599x family (e.g., MSP430FR5994). The MSP430FR5962IZVWR retains all other core peripherals-including 16-bit timers, eUSCI modules, ADC12_B, and AES-but omits LEA's 4KB shared RAM and FFT acceleration capability. Signal processing tasks must be executed on the CPU or offloaded externally.
