Product details
Overview
MSP430FR5958IRHAR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, 12-bit ADC (14 external channels), RTC with calendar/alarm, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets energy-harvested sensor nodes and wearable electronics.
For engineers reviewing the MSP430FR5958IRHAR datasheet, MSP430FR5958IRHAR pinout, MSP430FR5958IRHAR application, or MSP430FR5958IRHAR equivalent, key selection criteria include HFXT oscillator support, 40-pin VQFN (RHA) package, FRAM endurance (10¹⁵ writes), LPM3.5 current (0.25 µA typical), and integrated AES256 encryption coprocessor.
Technical Context
The MSP430FR5958IRHAR implements the CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or external HFXT (4–24 MHz). Its memory subsystem unifies 48KB FRAM for code, data, and storage-enabling instant write persistence without erase cycles.
Peripherals include three 16-bit Timer_A modules (TA0/TA1/TA2), one 16-bit Timer_B (TB0) with seven capture/compare registers, 32-bit hardware multiplier, 3-channel DMA, and dual eUSCI interfaces: eUSCI_A0/A1 support UART/IrDA/SPI, while eUSCI_B0 supports I²C/SPI. The device lacks LFXT pins but includes HFXIN/HFXOUT for high-frequency crystal operation.

FAQ
What is the maximum operating frequency of the MSP430FR5958IRHAR?
The MSP430FR5958IRHAR supports a maximum system clock frequency of 16 MHz, achievable using either the internal digitally controlled oscillator (DCO) with factory trimming or an external high-frequency crystal (HFXT) connected to PJ.6/HFXIN and PJ.7/HFXOUT. This frequency enables real-time signal processing and high-speed serial communication without exceeding ultra-low-power design goals.
Does the MSP430FR5958IRHAR include a real-time clock (RTC) module?
Yes, the MSP430FR5958IRHAR includes the RTC_B module with calendar and alarm functions. It operates in LPM3.5 mode at 0.25 µA typical current draw. While the device lacks dedicated LFXT pins, the RTC can be clocked by a 32-kHz external crystal connected via GPIO or driven by a DCO-derived clock - confirmed in TI's SLAS704G datasheet Section 1.1 and Figure 1-1.
What package type and pin count does the MSP430FR5958IRHAR use?
The MSP430FR5958IRHAR uses a 40-pin VQFN package (RHA variant), measuring 6 mm × 6 mm with 0.5 mm pitch and an exposed thermal pad. This package is explicitly listed in TI's SLAS704G datasheet Table 3-1 and Figure 4-4, and is distinct from the 48-pin RGZ used by higher-pin-count variants like the MSP430FR596x series.
How many analog input channels does the ADC12_B module support on the MSP430FR5958IRHAR?
The ADC12_B module on the MSP430FR5958IRHAR supports up to 14 external analog input channels (A0–A15 excluding A6 and A7), as specified in Table 3-1 of the SLAS704G datasheet. This matches the MSP430FR595x family specification and is confirmed by pin mapping: P1.0–P1.5, P3.0–P3.3, P4.0–P4.1, and P2.3–P2.4 provide ADC-capable pins totaling 14 usable channels.
Is the MSP430FR5958IRHAR compatible with the MSP430FR5959IRHAR in terms of pinout and software?
Yes, the MSP430FR5958IRHAR and MSP430FR5959IRHAR share identical 40-pin RHA package pinouts, register-level peripheral architecture, and instruction set. They differ only in FRAM size (48KB vs. 64KB) and associated memory-mapped address space - making them software-compatible and drop-in replacements where memory requirements permit.
