Product details
Overview
MSP430FR5868IRGZR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in a 48-pin VQFN package, featuring 48KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 16 external channels, RTC with calendar/alarm, and dual eUSCI modules (UART/IrDA/SPI + I²C/SPI). It targets battery-powered sensor nodes and metering systems requiring long-term data retention without write endurance limits.
For engineers reviewing the MSP430FR5868IRGZR datasheet, MSP430FR5868IRGZR pinout, MSP430FR5868IRGZR application, or MSP430FR5868IRGZR equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LPM3.5 current (0.25 µA typical), RTC calendar support, 48-pin RGZ package compatibility, and UART/I²C bootloader capability.
Technical Context
The MSP430FR5868IRGZR implements the CPUXV2 16-bit RISC core with 16-MHz max clock, integrated 32-bit hardware multiplier and 3-channel DMA for efficient signal processing. Its memory subsystem unifies 48KB FRAM for code, data, and logging - eliminating separate flash/EEPROM partitions and enabling atomic writes without erase cycles.
Peripherals include five 16-bit timers (TA0–TA3, TB0), 16-channel analog comparator, CRC16 engine, and flexible clock system with DCO, LFXT (32 kHz crystal), and HFXT (up to 24 MHz) support. The device supports capacitive touch on all I/O pins without external components and includes hardware UART and I²C bootloader (BSL).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5869IRGZR | 64KB FRAM, identical peripherals and package - differs only in FRAM capacity and part marking. | Same use cases; preferred when >48KB persistent storage needed for firmware+logs+OTA images. | Select MSP430FR5869IRGZR if future firmware expansion or extended logging duration is required. |
| MSP430FR5848IRHA | 48KB FRAM, 40-pin VQFN (6 mm × 6 mm), no HFXT - lacks HFXIN/HFXOUT pins and high-frequency crystal support. | Suitable for cost-sensitive, space-constrained designs where 16-MHz CPU speed is not required. | Choose MSP430FR5848IRHA only if board layout prioritizes smaller footprint and HFXT is unused. |
Compared with MSP430FR5869IRGZR, the MSP430FR5868IRGZR trades 16KB FRAM for identical low-power performance and peripheral set; versus MSP430FR5848IRHA, it adds HFXT support and larger package for higher I/O count and thermal margin - critical for sustained ADC or radio coexistence.

FAQ
What is the maximum operating frequency of the MSP430FR5868IRGZR?
The MSP430FR5868IRGZR supports a maximum CPU clock frequency of 16 MHz using the integrated DCO or an external HFXT crystal up to 24 MHz. This enables high-speed ADC sampling, real-time signal processing, and responsive communication stack execution while maintaining ultra-low-power architecture compliance.
Does the MSP430FR5868IRGZR support hardware encryption or secure boot?
The MSP430FR5868IRGZR does not include dedicated AES hardware or secure boot circuitry. It features a Memory Protection Unit (MPU) with IP encapsulation for code/data region access control and supports software-based cryptographic libraries. Secure firmware updates rely on the hardware UART/I²C bootloader with password protection.
Can the MSP430FR5868IRGZR operate without an external crystal?
Yes - the MSP430FR5868IRGZR can operate using its internal DCO (digitally controlled oscillator) or VLO (very-low-power oscillator) for basic timing. However, the RTC calendar function and precise ADC sampling require the external 32-kHz LFXT crystal on PJ.4/PJ.5; HFXT is optional but needed for full 16-MHz CPU performance.
How many I²C interfaces does the MSP430FR5868IRGZR support?
The MSP430FR5868IRGZR supports one hardware I²C interface via eUSCI_B0 on pins P1.6 (SDA) and P1.7 (SCL). This module also supports SPI mode, but only one concurrent I²C master/slave instance is available. Additional I²C buses require bit-banged GPIO implementation.
Is the MSP430FR5868IRGZR pin-compatible with other devices in the MSP430FR586x family?
Yes - the MSP430FR5868IRGZR is pin-compatible with MSP430FR5869IRGZR, MSP430FR5867IRGZR, and MSP430FR58671IRGZR in the 48-pin RGZ package. All share identical pin functions, electrical characteristics, and mechanical footprint, allowing drop-in replacement within the same FRAM capacity tier or firmware-compatible upgrades.
