Product details
Overview
MSP430FR58671IRGZR 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. It operates from 1.8 V to 3.6 V and targets energy-constrained sensor nodes and data loggers.
For engineers reviewing the MSP430FR58671IRGZR datasheet, MSP430FR58671IRGZR pinout, MSP430FR58671IRGZR application, or MSP430FR58671IRGZR equivalent, key selection criteria include its I²C-capable BSL, 48-pin VQFN package, LPM3.5 current of 0.25 µA, FRAM endurance (10¹⁵ writes), and capacitive touch I/O support without external components.
Technical Context
The MSP430FR58671IRGZR implements the CPUXV2 16-bit RISC core with hardware multiplier and 3-channel DMA, enabling efficient signal processing in low-power modes. Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (up to 24 MHz) for flexible timing across active and sleep states.
It features a unified FRAM memory map (code + data + storage), eliminating separate flash/EEPROM partitions. The RTC_B module requires LFXT connection and supports calendar, alarm, and calibration functions - confirmed for MSP430FR5x6x devices including this variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5867IRGZR | Identical FRAM/RAM size and pinout; UART-based BSL instead of I²C BSL | Requires UART interface for firmware updates; lacks native two-wire update capability | Select when UART debug/programming infrastructure already exists and I²C BSL is unnecessary |

FAQ
What is the primary difference between MSP430FR58671IRGZR and MSP430FR5867IRGZR?
The MSP430FR58671IRGZR features an I²C-based hardware bootloader (BSL) on pins P1.6 (SDA) and P1.7 (SCL), whereas the MSP430FR5867IRGZR uses a UART-based BSL on P2.0/P2.1. Both share identical FRAM (32 KB), RAM (1 KB), package (VQFN-48), and peripheral sets - only the BSL interface differs. This makes MSP430FR58671IRGZR ideal for systems lacking UART resources but equipped with I²C.
Does MSP430FR58671IRGZR support high-frequency crystal oscillation (HFXT)?
Yes, MSP430FR58671IRGZR supports HFXT up to 24 MHz via PJ.6 (HFXIN) and PJ.7 (HFXOUT). This is confirmed in the device comparison table and functional block diagram for MSP430FR5x6x devices. HFXT enables precise timing for high-speed communication, PWM generation, and RF subsystem synchronization - distinct from MSP430FR584x variants that omit HFXT.
What is the minimum supply voltage for MSP430FR58671IRGZR in active mode?
The minimum supply voltage for MSP430FR58671IRGZR in active mode is 1.8 V, as specified in the Recommended Operating Conditions section. Operation below this voltage is restricted by SVS (Supply Voltage Supervisor) thresholds and may cause undefined behavior or brownout reset. The datasheet explicitly states "Minimum Supply Voltage is Restricted by SVS Levels" - confirming 1.8 V as the functional lower bound.
Can MSP430FR58671IRGZR operate in real-time clock mode with full memory retention?
Yes, MSP430FR58671IRGZR supports LPM3.5 mode with RTC_B active and full FRAM/SRAM retention at 0.25 µA typical current. This requires connection of a 32-kHz crystal to PJ.4 (LFXIN) and PJ.5 (LFXOUT). The RTC_B module - confirmed for MSP430FR5x6x devices - provides calendar, alarm, and calibration functions while preserving all memory contents.
How many capture/compare registers does the Timer_B0 module have in MSP430FR58671IRGZR?
The Timer_B0 module in MSP430FR58671IRGZR has seven capture/compare registers, as documented in the functional block diagram and device comparison table. This is consistent across all MSP430FR586x and MSP430FR586x1 variants. TB0 supports both internal and external capture/compare inputs and PWM outputs - critical for motor control, LED dimming, and signal generation tasks.
