Product details
Overview
MSP430FR5727IRHAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB ferroelectric RAM (FRAM), 1KB SRAM, 8-MHz CPU, 16-channel analog comparator, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 2 V to 3.6 V across –40°C to 85°C and targets battery-powered sensor nodes requiring nonvolatile memory endurance and RTC functionality.
For engineers reviewing the MSP430FR5727IRHAT datasheet, MSP430FR5727IRHAT pinout, MSP430FR5727IRHAT application, or MSP430FR5727IRHAT equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LPM3.5 RTC current (1.5 µA), 40-pin RHA package compatibility, and absence of integrated ADC-critical for analog-sensor interface planning.
Technical Context
The MSP430FR5727IRHAT implements a 16-bit CPUXV2 core with hardware multiplier and three-channel DMA, paired with a flexible clock system including DCO, VLO, LFXT, and HFXT sources. Its power management includes SVS, BOR, and zero-power brownout detection, enabling robust operation in energy-constrained environments.
Peripherals include five 16-bit timers (TA0/TA1/TB0/TB1/TB2), CRC engine, MPU, boot ROM, and two eUSCI_A modules (UART/IrDA/SPI) plus one eUSCI_B module (I²C/SPI). The device lacks ADC functionality per family comparison data-confirmed by Table 3-1-and relies on external analog front-ends or comparator-based sensing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5729IRHAT | Includes 12-channel external ADC (ADC10_B); same FRAM/SRAM/timers/peripherals | Required for direct analog sensor interfacing (e.g., thermistor, voltage monitoring) | Select when analog signal acquisition is needed-MSP430FR5727IRHAT requires external ADC or comparator-based threshold detection. |
| MSP430FR5725IRHAT | 8 KB FRAM (vs. 16 KB); identical package, peripherals, and power specs | Suitable for firmware with smaller code footprint or less logging depth | Choose for cost-sensitive designs where 8 KB FRAM suffices-no layout change required due to RHA pin compatibility. |
Compared with MSP430FR5729IRHAT, the MSP430FR5727IRHAT omits ADC but retains full FRAM capacity and RTC capability-making it optimal for digital-event logging. Against MSP430FR5725IRHAT, it doubles nonvolatile storage while maintaining identical power and interface behavior.

FAQ
Does MSP430FR5727IRHAT include an integrated analog-to-digital converter (ADC)?
No, the MSP430FR5727IRHAT does not include an ADC. Per Table 3-1 in the official datasheet, MSP430FR5727 variants have "–" under the ADC10_B column, confirming absence of integrated analog-to-digital conversion. Designers must use external ADCs or rely on the 16-channel analog comparator for threshold-based sensing. This distinguishes MSP430FR5727IRHAT from MSP430FR5729IRHAT and MSP430FR5725IRHAT, which include ADC functionality.
What is the package type and pin count of MSP430FR5727IRHAT?
The MSP430FR5727IRHAT uses a 40-pin VQFN package (RHA variant), measuring 6 mm × 6 mm with an exposed thermal pad. Pin configuration matches other RHA-packaged family members including MSP430FR5729IRHAT and MSP430FR5725IRHAT, enabling drop-in compatibility in layouts designed for this footprint. The thermal pad must be connected to DVSS for optimal thermal performance.
How does the FRAM memory in MSP430FR5727IRHAT differ from traditional flash memory?
The MSP430FR5727IRHAT features 16 KB of ferroelectric RAM (FRAM) offering 10¹⁵ write cycles, 125 ns write speed per word, and no erase-before-write requirement-unlike flash memory. This enables true EEPROM-like usage for logging, parameter storage, and firmware updates without wear leveling or block management overhead. FRAM also operates at lower active power and retains data without refresh during standby modes.
Can MSP430FR5727IRHAT operate from a single 3-V lithium coin cell?
Yes, the MSP430FR5727IRHAT supports a supply voltage range of 2.0 V to 3.6 V, making it compatible with standard 3-V lithium coin cells (e.g., CR2032) across its full operating temperature range (–40°C to +85°C). Its LPM4.5 shutdown current of 0.32 µA ensures multi-year operation on a single cell when paired with duty-cycled peripherals and RTC wake-up intervals.
What debug interface does MSP430FR5727IRHAT support?
The MSP430FR5727IRHAT supports Spy-Bi-Wire (SBW) debugging via two pins: RST/NMI/SBWTDIO (data I/O) and TEST/SBWTCK (clock). This 2-wire interface replaces full 4-pin JTAG, reducing PCB routing complexity and connector footprint. SBW enables full in-system programming, real-time debugging, and memory inspection using TI's MSP-FET430U40A or compatible tools.
