Product details
Overview
MSP430FR5964IZVWR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 256KB FRAM, 8KB RAM, 16-channel 12-bit ADC, 16-bit timers (3× Timer_A, 2× Timer_B), and four eUSCI_A (UART/IrDA/SPI) and four eUSCI_B (I²C/SPI) interfaces. It operates from 1.8 V to 3.6 V and targets battery-powered sensing and control applications requiring nonvolatile memory endurance and sub-µA standby.
For engineers reviewing the MSP430FR5964IZVWR datasheet, MSP430FR5964IZVWR pinout, MSP430FR5964IZVWR application, or MSP430FR5964IZVWR equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LPM3.5 RTC current (350 nA), capacitive-touch I/O support, AES-256 encryption coprocessor, and NFBGA-87 package compatibility with high-density PCB layouts.
Technical Context
The MSP430FR5964IZVWR implements a 16-bit RISC CPUXV2 core with up to 16 MHz operation, integrated FRAM controller (FRCTL_A), and memory protection unit (MPU) with IP encapsulation. Its clock system includes DCO, LFXT (32 kHz crystal), and HFXT (up to 24 MHz), enabling precise timing for RTC, ADC sampling, and serial communication.
Unlike the MSP430FR599x series, this device omits the Low-Energy Accelerator (LEA) subsystem-confirmed by Device Comparison Table 6-1-and relies on CPU-executed signal processing. All 68 GPIO pins support capacitive-touch sensing without external components, and six-channel DMA enables autonomous peripheral data movement during low-power modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5962IZVWR | 128 KB FRAM, same 8 KB RAM, identical peripherals and package - no LEA, same LPM currents | Suitable where firmware size < 128 KB and cost sensitivity outweighs memory headroom | Select when application code and data fit within 128 KB FRAM and BOM cost is prioritized |
| MSP430FR5964IPNR | LQFP-80 package (12 mm × 12 mm), same FRAM/RAM/peripherals - larger footprint, easier hand-soldering | Preferred for prototyping, low-volume production, or designs requiring manual rework | Choose for development boards or industrial controls where NFBGA assembly complexity is prohibitive |
Compared with MSP430FR5962IZVWR, the MSP430FR5964IZVWR offers double FRAM capacity for future firmware expansion and complex data buffering; versus MSP430FR5964IPNR, it delivers higher board density at the cost of requiring automated assembly - both retain identical functional behavior and ultra-low-power performance.

FAQ
What is the maximum operating frequency of the MSP430FR5964IZVWR?
The MSP430FR5964IZVWR supports a maximum CPU clock frequency of 16 MHz, achieved using the integrated digitally controlled oscillator (DCO) or external high-frequency crystal (HFXT) up to 24 MHz. This frequency enables real-time signal processing, fast ADC conversions, and responsive serial communication while maintaining ultra-low-power efficiency across all active and low-power modes.
Does the MSP430FR5964IZVWR include a low-energy accelerator (LEA)?
No, the MSP430FR5964IZVWR does not include the Low-Energy Accelerator (LEA) subsystem. As confirmed in Table 6-1 of the official datasheet SLASE54D, LEA is exclusive to the MSP430FR599x family (e.g., MSP430FR5994). The MSP430FR5964IZVWR relies on its 16-bit CPUXV2 core and 6-channel DMA for signal processing tasks, with no dedicated hardware acceleration for FFT or FIR operations.
What package type and dimensions does the MSP430FR5964IZVWR use?
The MSP430FR5964IZVWR uses an 87-ball NFBGA package (ZVW), with a 6 mm × 6 mm body size and 0.4 mm ball pitch. The bottom thermal pad must be connected to DVSS for thermal and electrical integrity. This compact, high-I/O-density package is designed for space-constrained applications such as portable medical devices and smart meters where PCB real estate is limited.
How many I²C interfaces does the MSP430FR5964IZVWR support?
The MSP430FR5964IZVWR supports four eUSCI_B modules, each configurable as an I²C master or slave interface with multiple-slave addressing capability. These interfaces operate independently and can be assigned to different GPIO pins via port mapping, enabling concurrent communication with up to four I²C sensor clusters - for example, temperature, humidity, pressure, and gas sensors - without software arbitration overhead.
What is the standby current consumption of the MSP430FR5964IZVWR with RTC enabled?
The MSP430FR5964IZVWR consumes 350 nA in LPM3.5 mode with the real-time clock (RTC) active and powered by a 3.7-pF 32.768 kHz crystal. This ultra-low current enables multi-year battery operation in time-critical applications such as utility metering, environmental logging, and asset tracking, where accurate timekeeping and infrequent wake-up events define system energy budget.
