Product details
Overview
MSP430FR5964IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 256KB FRAM, 8KB RAM, 16-channel 12-bit ADC, six 16-bit timers, four eUSCI_A (UART/IrDA/SPI) and four eUSCI_B (I²C/SPI) interfaces, and AES-256 encryption coprocessor - designed for battery-powered industrial sensing and metering applications requiring nonvolatile memory endurance and sub-μA standby current.
For engineers reviewing the MSP430FR5964IPMR datasheet, MSP430FR5964IPMR pinout, MSP430FR5964IPMR application, or MSP430FR5964IPMR equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LPM3.5 RTC current (350 nA), capacitive-touch I/O support, UART/I²C bootloader capability, and absence of Low-Energy Accelerator (LEA) - distinguishing it from MSP430FR599x variants.
Technical Context
The MSP430FR5964IPMR implements a CPUXV2 16-bit RISC core with up to 16-MHz operation, DCO/LFXT/HFXT clock sources, and SVS brownout protection down to 1.8 V. It integrates FRAM controller A (FRCTL_A) for unified memory access, MPU with IP encapsulation for code security, and DMA-driven peripheral operation across six channels.
Its analog subsystem includes a 12-bit ADC with window comparator, internal reference, and sample-and-hold supporting up to 20 external inputs; a 16-channel analog comparator (Comp_E); and RTC with calendar/alarm functions clocked by 32-kHz crystal. All I/O pins support capacitive touch without external components and edge-selectable wake from LPM.

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 |
|---|---|---|---|
| MSP430FR5962IPMR | 128 KB FRAM (vs. 256 KB), same 8 KB RAM, identical peripherals and power specs | Lower memory footprint suits simpler metering or sensor endpoints without firmware update or data logging needs | Select when application code + data fits within 128 KB FRAM and cost sensitivity outweighs future scalability. |
| MSP430FR5994IPMR | Includes Low-Energy Accelerator (LEA), 256 KB FRAM, same package - adds 4 KB shared RAM and FFT acceleration | Required for on-device FFT-based vibration analysis or audio preprocessing where MSP430FR5964IPMR lacks DSP capability | Choose only if LEA-accelerated signal processing is mandatory; otherwise MSP430FR5964IPMR offers identical base functionality at lower cost. |
Compared with MSP430FR5962IPMR, the MSP430FR5964IPMR doubles FRAM capacity for robust OTA updates and data buffering; versus MSP430FR5994IPMR, it removes LEA to reduce cost and power in applications not requiring hardware-accelerated DSP - making it the optimal balance of memory, security, and ultra-low-power I/O for industrial sensing.

FAQ
What is the maximum operating frequency of the MSP430FR5964IPMR?
The MSP430FR5964IPMR operates at up to 16 MHz using its digitally controlled oscillator (DCO) or external crystal sources (HFXT up to 24 MHz). This frequency supports real-time sensor fusion and communication stack execution while maintaining ultra-low active-mode current of 118 µA/MHz - verified in TI's SLASE54D datasheet Section 8.5.
Does the MSP430FR5964IPMR include a hardware Low-Energy Accelerator (LEA)?
No, the MSP430FR5964IPMR does not include the Low-Energy Accelerator. LEA is exclusive to the MSP430FR599x series (e.g., MSP430FR5994IPMR). The MSP430FR5964IPMR retains all other peripherals - including 256 KB FRAM, 12-bit ADC, AES-256, and eight eUSCI modules - but omits LEA to optimize cost and power for applications not requiring FFT or FIR acceleration.
What package type and pin count does the MSP430FR5964IPMR use?
The MSP430FR5964IPMR uses a 64-pin LQFP (PM) package with 10 mm × 10 mm body size and exposed thermal pad. Pin functions are defined in TI's SLASE54D datasheet Figure 7-4 and Table 7-2, supporting full peripheral mapping including eUSCI_A/B, ADC inputs, timers, and crystal interfaces - distinct from the 80-pin PN and 87-pin ZVW variants in the same family.
How does the MSP430FR5964IPMR handle secure firmware updates?
The MSP430FR5964IPMR supports secure firmware updates via its hardware AES-256 coprocessor and IP encapsulation memory protection. Encrypted images are decrypted in real time during UART or I²C bootloader (BSL) execution, while MPU-enforced memory isolation prevents unauthorized readout of keys or application code - meeting industrial cybersecurity requirements without external secure elements.
What is the lowest achievable standby current for the MSP430FR5964IPMR with RTC enabled?
The lowest verified standby current for the MSP430FR5964IPMR with RTC enabled is 350 nA in LPM3.5 mode, achieved when the RTC is clocked by a 3.7-pF 32-kHz crystal (as specified in SLASE54D Section 1, Features). This value assumes proper configuration of SVS levels, disabled unused peripherals, and DVSS/DVCC decoupling - enabling multi-year operation on coin-cell batteries.
