Product details
Overview
MSP430FR58671IRGZT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 32KB nonvolatile memory, 1KB RAM, 12-bit ADC (16-channel), RTC with calendar/alarm, and dual eUSCI modules supporting UART, SPI, and I²C - deployed in battery-powered sensor nodes and energy-harvesting data loggers.
For engineers reviewing the MSP430FR58671IRGZT datasheet, MSP430FR58671IRGZT pinout, MSP430FR58671IRGZT application, or MSP430FR58671IRGZT equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (0.25 µA typical), I²C bootloader support, 48-pin VQFN package, and RTC operation with 32-kHz crystal.
Technical Context
The MSP430FR58671IRGZT implements the CPUXV2 16-bit RISC core with up to 16-MHz DCO clock, integrated 32-bit hardware multiplier, and three-channel DMA. Its FRAM memory architecture enables simultaneous read/write without erase cycles and eliminates write latency penalties inherent in flash-based MCUs.
It features dual eUSCI peripherals: eUSCI_A0/A1 support UART (with auto-baud detection) and SPI, while eUSCI_B0 supports I²C (multi-address) and SPI - with dedicated BSL pins (P1.6/SDA, P1.7/SCL) for I²C-based firmware updates. The RTC_B module requires LFXT (32-kHz crystal) and operates in LPM3.5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5867IRGZT | Identical FRAM/RAM size, pinout, and peripherals but UART BSL (P2.0/P2.1) instead of I²C BSL. | Suitable where UART-based firmware update infrastructure already exists; lacks native I²C BSL capability. | Select when UART debug/programming channel is preferred and I²C BSL is not required. |
| MSP430FR58471IRHAT | 32KB FRAM/1KB RAM, 40-pin VQFN, LFXT-only (no HFXT), 14 ADC inputs, I²C BSL - same BSL interface but smaller package and reduced analog channel count. | Better suited for space-constrained, low-channel-count sensor nodes without high-frequency crystal needs. | Select for compact designs needing I²C BSL and lower pin count, accepting fewer ADC channels and no HFXT support. |

FAQ
What is the primary memory technology used in the MSP430FR58671IRGZT?
The MSP430FR58671IRGZT uses ferroelectric RAM (FRAM) for its 32KB main memory. This nonvolatile technology combines the speed and endurance of SRAM with the data retention of flash, enabling 125 ns writes and 10¹⁵ write cycles. Unlike flash, FRAM requires no erase cycles, allowing true simultaneous read/write operations - critical for reliable data logging in the MSP430FR58671IRGZT.
Does the MSP430FR58671IRGZT support real-time clock functionality with calendar and alarm features?
Yes, the MSP430FR58671IRGZT integrates the RTC_B module with full calendar and alarm capabilities. It operates in LPM3.5 mode at 0.25 µA typical current when driven by a 32-kHz crystal connected to PJ.4/LFXIN and PJ.5/LFXOUT. The MSP430FR58671IRGZT RTC supports time-of-day tracking, date, month, year, and programmable alarms - all retained during ultra-low-power sleep states.
Which serial interfaces does the MSP430FR58671IRGZT support, and how is the bootloader accessed?
The MSP430FR58671IRGZT supports UART, SPI, and I²C via two eUSCI_A modules (A0/A1) and one eUSCI_B module (B0). Its hardware bootloader (BSL) is I²C-only, using dedicated pins P1.6 (BSLSDA) and P1.7 (BSLSCL). This allows firmware updates over I²C without requiring UART lines or JTAG, making the MSP430FR58671IRGZT ideal for sealed or space-constrained deployments.
What package type and pin count does the MSP430FR58671IRGZT use?
The MSP430FR58671IRGZT is packaged in a 48-pin VQFN (RGZ) with 7 mm × 7 mm body size and an exposed thermal pad. Pin assignments match the MSP430FR586x family, including dedicated LFXIN/LFXOUT for RTC, HFXIN/HFXOUT for high-frequency crystal, and I²C BSL pins. TI specifies connection of the thermal pad to DVSS for thermal and electrical stability in the MSP430FR58671IRGZT.
How does the MSP430FR58671IRGZT achieve ultra-low power consumption in standby modes?
The MSP430FR58671IRGZT achieves ultra-low power via seven optimized low-power modes (LPMs), including LPM3.5 (0.25 µA with RTC) and LPM4.5 (0.02 µA shutdown). Its FRAM eliminates flash erase overhead, and intelligent peripherals like DMA allow autonomous sensor data movement without CPU wake-up. These features collectively extend battery life in applications such as environmental monitoring - a defining characteristic of the MSP430FR58671IRGZT.
