Product details
Overview
MSP430FR5868IRGZT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, and integrated 12-bit ADC, RTC, and five 16-bit timers. It operates from 1.8 V to 3.6 V and supports LFXT/HFXT crystal oscillators for precision timing in battery-constrained metering and sensor node applications.
For engineers reviewing the MSP430FR5868IRGZT datasheet, MSP430FR5868IRGZT pinout, MSP430FR5868IRGZT application, or MSP430FR5868IRGZT equivalent, key selection criteria include FRAM endurance (1015 write cycles), LPM3.5 current (0.25 µA typical), RTC calendar/alarm support, 48-pin VQFN package compatibility, and UART/I²C/SPImulti-protocol eUSCI peripherals.
Technical Context
The MSP430FR5868IRGZT implements the CPUXV2 16-bit RISC core with hardware multiplier and 3-channel DMA, enabling deterministic real-time control. Its clock system integrates DCO (10 factory-trimmed frequencies), VLO, LFXT (32 kHz), and HFXT (up to 24 MHz) sources, with automatic clock fail-safe switching.
Peripherals include ADC12_B (16 external + 2 internal analog inputs), Comp_E (16-channel comparator), RTC_B (calendar mode with alarm), and dual eUSCI modules: eUSCI_A0/A1 (UART/IrDA/SPI) and eUSCI_B0 (I²C/SPI). All I/O pins support capacitive touch sensing without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5869IRGZT | 64 KB FRAM, same package and pinout - adds 16 KB nonvolatile storage capacity | Required when extended firmware image size or larger event log buffer is needed | Select if future firmware growth or long-term data retention beyond 48 KB is anticipated |
| MSP430FR5867IRGZT | 32 KB FRAM, 1 KB RAM - reduced memory and no RTC_B module per device comparison table | Not suitable for calendar/time-stamped logging; limited for complex algorithm execution | Choose only for cost-sensitive, time-insensitive sensor endpoints where RTC is unnecessary |
Compared with MSP430FR5869IRGZT, the MSP430FR5868IRGZT trades 16 KB FRAM for identical low-power performance and RTC capability; versus MSP430FR5867IRGZT, it delivers double FRAM and full RTC functionality - making it the optimal balance for time-aware, memory-constrained embedded systems.

FAQ
What is the maximum operating frequency of the MSP430FR5868IRGZT?
The MSP430FR5868IRGZT supports up to 16 MHz system clock via its HFXT oscillator (with external crystal) or DCO. The CPUXV2 core executes instructions at this rate, enabling real-time processing of ADC samples, timer events, and communication protocols without pipeline stalls.
Does the MSP430FR5868IRGZT include a hardware real-time clock (RTC)?
Yes, the MSP430FR5868IRGZT includes the RTC_B module with calendar, alarm, and LPM3.5 operation. It requires connection of a 32.768 kHz crystal to PJ.4/LFXIN and PJ.5/LFXOUT to achieve accurate timekeeping with 0.25 µA typical current draw in RTC-only mode.
Can the MSP430FR5868IRGZT perform capacitive touch sensing without external components?
Yes, all GPIO pins on the MSP430FR5868IRGZT support capacitive touch sensing using the built-in CapTIvate™-compatible hardware. No external resistors, capacitors, or dedicated touch controller ICs are required - reducing BOM count and PCB area.
What bootloading interfaces does the MSP430FR5868IRGZT support?
The MSP430FR5868IRGZT supports both UART and I²C hardware bootloaders (BSL). UART BSL uses P2.0 (TX) and P2.1 (RX); I²C BSL uses P1.6 (SDA) and P1.7 (SCL). Both operate at reset and require no user firmware intervention.
Is the MSP430FR5868IRGZT pin-compatible with other devices in the MSP430FR586x family?
Yes, the MSP430FR5868IRGZT shares identical 48-pin VQFN (RGZ) package and pinout with MSP430FR5869IRGZT and MSP430FR5867IRGZT. This enables drop-in replacement within the same footprint, provided firmware accommodates differences in FRAM size and RTC_B availability.
