Product details
Overview
MSP430FR5727IRHAR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in a 40-pin VQFN (RHA) package, featuring 16KB FRAM, 1KB RAM, 8-MHz CPU, 16-channel analog comparator, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It targets battery-powered sensor nodes requiring RTC, low-power wake-up, and nonvolatile data logging.
For engineers reviewing the MSP430FR5727IRHAR datasheet, MSP430FR5727IRHAR pinout, MSP430FR5727IRHAR application, or MSP430FR5727IRHAR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (1.5 µA), 10-bit ADC with 12 external channels, and RHA-package I/O count (32 pins).
Technical Context
The MSP430FR5727IRHAR implements the MSP430xV2 CPU core with unified FRAM memory architecture enabling simultaneous code execution and data write operations without wait states. Its power management includes SVS/BOR, integrated LDO, and five low-power modes - LPM0–LPM4.5 - with sub-µA shutdown (0.32 µA typical).
Peripherals are tightly coupled via three-channel DMA and clocked by flexible sources: DCO (up to 8 MHz), VLO, LFXT (32 kHz crystal), and HFXT. The device lacks on-chip ADC per family comparison data but retains full 16-channel Comparator_D, five 16-bit timers (TA0/TA1/TB0/TB1/TB2), and hardware CRC/MPY32.

FAQ
What is the FRAM capacity and endurance specification for the MSP430FR5727IRHAR?
The MSP430FR5727IRHAR integrates 16KB of ferroelectric RAM (FRAM) with 10¹⁵ write cycle endurance, 125 ns per word write speed, and built-in error correction coding (ECC). Unlike flash, FRAM allows simultaneous read/write operations with zero wait states, making it ideal for high-frequency data logging in battery-powered applications. This specification is confirmed in the SLASE35C datasheet Section 1.1 and Table 3-1.
Does the MSP430FR5727IRHAR include an analog-to-digital converter (ADC)?
No, the MSP430FR5727IRHAR does not include an ADC. As confirmed in Table 3-1 of the SLASE35C datasheet, the MSP430FR5727 variant lists "–" under the ADC10_B column, distinguishing it from MSP430FR5729 (12 ext/2 int channels) and MSP430FR5725 (12 ext/2 int channels). It retains the full 16-channel Comparator_D subsystem for threshold-based analog monitoring.
What package type and pin count does the MSP430FR5727IRHAR use?
The MSP430FR5727IRHAR uses a 40-pin VQFN package designated RHA, measuring 6 mm × 6 mm with an exposed thermal pad. This is explicitly listed in the Device Information table (Section 1.3) and verified in Figure 4-1 (Pin Diagram – RHA Package) of the SLASE35C datasheet, which applies to MSP430FR5721/5723/5725/5727/5729.
What are the lowest power consumption modes supported by the MSP430FR5727IRHAR?
The MSP430FR5727IRHAR supports seven low-power modes. The lowest active-retention modes are LPM3.5 (RTC with 32-kHz crystal): 1.5 µA typical, and LPM4.5 (shutdown): 0.32 µA typical. These values are specified in Section 1.1 Features and validated in Section 5.5 of the SLASE35C datasheet. LPM3.5 maintains RTC/calendar functionality while minimizing current draw.
Which serial communication interfaces are available on the MSP430FR5727IRHAR?
The MSP430FR5727IRHAR features two eUSCI_A modules (eUSCI_A0 and eUSCI_A1) supporting UART, IrDA, and SPI, plus one eUSCI_B module (eUSCI_B0) supporting I²C and SPI. This configuration is documented in Section 1.1 Features and Table 3-1. All modules are fully functional in the RHA package, with dedicated pins mapped in Figure 4-1 and Table 4-1.
