Product details
Overview
MSP430FR5958IDA from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, and integrated peripherals including 12-bit ADC, RTC, AES-256 encryption, and dual eUSCI modules (UART/IrDA/SPI + I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and metering systems requiring long-term data retention without write endurance limits.
For engineers reviewing the MSP430FR5958IDA datasheet, MSP430FR5958IDA pinout, MSP430FR5958IDA application, or MSP430FR5958IDA equivalent, key selection criteria include FRAM write speed (125 ns/word), LPM3.5 current (0.25 µA typical), HFXT oscillator support, 38-pin TSSOP package compatibility, and UART/I²C bootloader capability.
Technical Context
The MSP430FR5958IDA implements the CPUXV2 core with 16 registers and supports seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its FRAM architecture enables unified memory space for code, data, and storage with 1015 write-cycle endurance and radiation resistance.
It integrates a 32-bit hardware multiplier, three-channel DMA, five 16-bit timers (including Timer_B with seven capture/compare registers), and dual eUSCI modules - eUSCI_A0/A1 supporting UART/IrDA/SPI and eUSCI_B0 supporting I²C/SPI - all configurable via register-level control without external components.

FAQ
What is the maximum operating frequency of the MSP430FR5958IDA?
The MSP430FR5958IDA supports a maximum system clock frequency of 16 MHz using the DCO or HFXT oscillator. This enables real-time signal processing and high-speed peripheral operation while maintaining ultra-low-power efficiency through dynamic voltage scaling and clock gating.
Does the MSP430FR5958IDA include hardware AES encryption?
Yes, the MSP430FR5958IDA integrates a dedicated 128-bit or 256-bit AES security coprocessor with random number seed generation. This enables fast, deterministic encryption/decryption for secure boot, firmware updates, and authenticated sensor data transmission without burdening the CPU.
What package type and pin count does the MSP430FR5958IDA use?
The MSP430FR5958IDA uses a 38-pin TSSOP (Thin Shrink Small Outline Package) with body dimensions of 12.5 mm × 6.2 mm. It is pin-compatible with other MSP430FR59xx DA variants and supports standard reflow soldering processes.
Can the MSP430FR5958IDA operate from a 1.8 V supply?
Yes, the MSP430FR5958IDA operates across a wide supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including FRAM access, ADC operation, and real-time clock accuracy - enabling direct integration with single-cell Li-ion or alkaline battery systems.
Is an external crystal required for the MSP430FR5958IDA to function?
No, the MSP430FR5958IDA can operate using its internal DCO or VLO oscillators without any external crystal. However, the HFXT oscillator (requiring PJ.6/HFXIN and PJ.7/HFXOUT) is necessary for precise high-frequency timing, such as accurate UART baud rates above 9600 or synchronous communication protocols.
