Product details
Overview
MSP430FR5959IRHAT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB 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 battery-powered sensor nodes and metering systems.
For engineers reviewing the MSP430FR5959IRHAT datasheet, MSP430FR5959IRHAT pinout, MSP430FR5959IRHAT application, or MSP430FR5959IRHAT equivalent, key selection criteria include HFXT oscillator support, 40-pin VQFN package dimensions (6 mm × 6 mm), FRAM endurance (10¹⁵ write cycles), LPM3.5 current (0.25 µA typical), and capacitive touch I/O capability on all pins.
Technical Context
The MSP430FR5959IRHAT integrates a 16-bit CPUXV2 core with up to 16 MHz operation, three 16-bit Timer_A modules (3/3/2 capture/compare registers), one 16-bit Timer_B (7 registers), and a 32-bit hardware multiplier. Its clock system includes DCO, VLO, and HFXT (not LFXT), enabling precise timing for real-time data acquisition and low-latency event response.
It features two eUSCI_A modules (UART/IrDA/SPI) and one eUSCI_B module (I²C/SPI), plus AES-256 encryption coprocessor, CRC-16 engine, and DMA controller with three channels - all optimized for secure, deterministic communication in energy-constrained edge devices without external memory or boot ROM.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5969IRGZ | 64KB FRAM, 48-pin VQFN, adds LFXT support and 2 extra ADC channels (16 ext) | Supports 32-kHz RTC crystal; suited for applications requiring ultra-precise timekeeping independent of HFXT | Select when LFXT-based RTC accuracy or additional analog inputs are required; not pin-compatible due to 48-pin vs 40-pin package |
| MSP430FR5949IRHAT | 64KB FRAM, 40-pin VQFN, LFXT-only clock system (no HFXT), 12 external ADC channels | Designed for low-frequency crystal use only; RTC functional with 32-kHz crystal but no HFXT option | Select for cost-sensitive designs where HFXT is unnecessary and 32-kHz timing suffices; same package but different clock architecture |
Compared with MSP430FR5969IRGZ and MSP430FR5949IRHAT, the MSP430FR5959IRHAT uniquely balances HFXT-driven timing flexibility and 40-pin compactness - making it optimal for space-constrained, high-accuracy sensor nodes needing robust RTC without LFXT component cost.

FAQ
What is the maximum operating frequency of the MSP430FR5959IRHAT?
The MSP430FR5959IRHAT 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 allows real-time execution of complex sensor fusion algorithms and communication stacks while maintaining ultra-low power consumption in active mode (≈100 µA/MHz).
Does the MSP430FR5959IRHAT support real-time clock functionality?
Yes, the MSP430FR5959IRHAT includes an RTC_B module that supports calendar and alarm functions. It operates in LPM3.5 mode with typical current draw of 0.25 µA and requires the HFXT oscillator (4–24 MHz) for timing - unlike LFXT-dependent variants. The RTCCLK signal is available on P1.0 for external synchronization.
What serial interfaces are available on the MSP430FR5959IRHAT?
The MSP430FR5959IRHAT integrates two eUSCI_A modules (supporting UART, IrDA, and SPI) and one eUSCI_B module (supporting I²C and SPI). This enables concurrent UART-based debug/logging, I²C-connected sensors, and SPI-driven displays or RF transceivers - all without external level shifters or protocol converters.
How does FRAM memory in the MSP430FR5959IRHAT differ from traditional flash?
The MSP430FR5959IRHAT uses 64KB of ferroelectric RAM (FRAM) offering near-SRAM write speeds (125 ns/word), unlimited write endurance (10¹⁵ cycles), and no erase-before-write requirement. Unlike flash, FRAM eliminates write latency and wear-leveling complexity - critical for frequent data logging in metering and predictive maintenance applications.
Is the MSP430FR5959IRHAT pin-compatible with other MSP430FR59xx devices in the same package?
No - the MSP430FR5959IRHAT uses the 40-pin VQFN (RHA) package but is not fully pin-compatible with MSP430FR594x or MSP430FR596x variants due to differing oscillator support (HFXT-only vs LFXT-only vs dual), RTC signal routing, and peripheral mapping. Always verify pin functions against Table 4-1 in the SLAS704G datasheet before board reuse.
