Product details
Overview
MSP430FR5964IPNR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 256 KB FRAM, 8 KB RAM, 16-MHz CPU, 12-bit ADC (20-channel), and 16-channel analog comparator - designed for battery-powered grid infrastructure and industrial sensing nodes requiring nonvolatile memory endurance and sub-μA standby operation.
For engineers reviewing the MSP430FR5964IPNR datasheet, MSP430FR5964IPNR pinout, MSP430FR5964IPNR application, or MSP430FR5964IPNR equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LPM3.5 current (350 nA with RTC), eUSCI_A/B serial interface count (7 UART/IrDA + 4 I²C/SPI), capacitive-touch I/O support, and absence of LEA accelerator versus FR599x variants.
Technical Context
The MSP430FR5964IPNR implements a CPUXV2 core with 16 registers, fixed-frequency DCO (10 factory-trimmed frequencies), LFXT/HFXT crystal support, and VLO internal clock. It lacks the Low-Energy Accelerator (LEA) subsystem found in MSP430FR599x devices, limiting on-chip DSP acceleration for FFT/FIR operations.
Its memory architecture integrates 256 KB FRAM (unified code/data space), 8 KB SRAM, and 22-byte Tiny RAM. Peripheral control uses a unified register map with MPY32 hardware multiplier, 6-channel DMA, and memory protection unit (MPU) with IP encapsulation for secure boot and code isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5962IPNR | 128 KB FRAM, same 8 KB RAM, identical peripheral set, no LEA | Lower memory footprint suits simpler metering or sensor nodes with static firmware | Select when application code + data fits within 128 KB FRAM and cost sensitivity outweighs memory headroom |
| MSP430FR5994IPNR | 256 KB FRAM + 4 KB LEA-shared RAM, includes Low-Energy Accelerator for FFT/FIR | Required for on-device signal processing (e.g., vibration analysis, ECG filtering) without host CPU | Choose when real-time DSP offload is mandatory; note LEA increases active-mode current by ~10% |
Compared with MSP430FR5962IPNR, the MSP430FR5964IPNR provides double FRAM capacity for larger firmware or data buffers; compared with MSP430FR5994IPNR, it omits LEA to reduce cost and active power, making it optimal for control-dominant rather than compute-intensive roles.

FAQ
Does the MSP430FR5964IPNR include a Low-Energy Accelerator (LEA)?
No, the MSP430FR5964IPNR does not include the Low-Energy Accelerator. That feature is exclusive to the MSP430FR599x series (e.g., MSP430FR5994). The MSP430FR5964IPNR retains full peripheral compatibility and FRAM benefits but omits LEA to optimize cost and power for control-centric applications.
What is the maximum operating frequency of the MSP430FR5964IPNR CPU?
The MSP430FR5964IPNR CPU operates at up to 16 MHz using its factory-trimmed DCO or external HFXT crystal. This frequency is fully supported across the entire recommended voltage range (1.8 V to 3.6 V), enabling deterministic real-time performance without dynamic voltage scaling.
How many eUSCI modules does the MSP430FR5964IPNR support?
The MSP430FR5964IPNR supports seven eUSCI_A modules (UART/IrDA/SPI) and four eUSCI_B modules (I²C/SPI). This configuration allows simultaneous use of multiple protocols - for example, UART for debugging, IrDA for remote setup, and I²C for sensor communication - without resource contention.
Is the MSP430FR5964IPNR pin-compatible with other MSP430FR59xx devices in LQFP-80?
Yes, the MSP430FR5964IPNR shares identical pinout, electrical characteristics, and package dimensions with MSP430FR5962IPNR, MSP430FR5994IPNR, and MSP430FR59941IPNR in the 80-pin LQFP (PN) package. Function mapping is consistent; only peripheral enable bits differ in software configuration.
What is the minimum supply voltage for the MSP430FR5964IPNR under LPM3.5 operation?
The MSP430FR5964IPNR supports LPM3.5 operation down to 1.8 V, provided the Supply Voltage Supervisor (SVS) threshold is configured accordingly. At 1.8 V, RTC remains functional with 350 nA current draw using a 3.7-pF crystal, meeting IEC 62056-21 and ANSI C12.1 metering standards.
