Product details
Overview
MSP430FR5869IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64KB ferroelectric RAM (FRAM), 2KB SRAM, 16-channel 12-bit ADC, real-time clock with calendar, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered metering and sensor node applications.
For engineers reviewing the MSP430FR5869IRGZR datasheet, MSP430FR5869IRGZR pinout, MSP430FR5869IRGZR application, or MSP430FR5869IRGZR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.25 µA typical), 48-pin VQFN package (7 mm × 7 mm), and integrated capacitive touch I/O without external components.
Technical Context
The MSP430FR5869IRGZR implements the CPUXV2 16-bit RISC core with hardware multiplier and three-channel DMA, enabling deterministic real-time processing. Its clock system integrates DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (high-frequency crystal) for flexible timing across active and low-power modes.
Peripherals include five 16-bit timers (TA0–TA3, TB0), RTC_B with alarm/calendar, 16-channel analog comparator (Comp_E), and eUSCI_A0/A1 (UART/IrDA/SPI) plus eUSCI_B0 (I²C/SPI), all accessible via multiplexed I/O pins in the 48-pin RGZ package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5868IRGZR | 48KB FRAM, same package and peripheral set; lacks 16KB FRAM capacity of MSP430FR5869IRGZR | Suitable where firmware size and data logging depth are reduced - e.g., simpler sensor nodes with shorter retention | Select when application code + data footprint fits within 48KB FRAM and cost optimization is prioritized |
| MSP430FR5969IPZ | 64KB FRAM, 2KB RAM, but 100-pin TQFP (PZ) package; adds USB and enhanced LCD support | Better suited for human-interface devices requiring display drivers or host connectivity - not drop-in compatible | Choose only if board redesign accommodates larger footprint and USB/LCD features justify migration |
Compared with MSP430FR5868IRGZR, the MSP430FR5869IRGZR provides 16KB additional FRAM for extended data buffering; versus MSP430FR5969IPZ, it offers identical memory and core specs in a smaller, lower-cost 48-pin VQFN - ideal for space-constrained, battery-operated designs.

FAQ
What is the maximum operating frequency of the MSP430FR5869IRGZR?
The MSP430FR5869IRGZR supports a maximum system clock frequency of 16 MHz using the high-frequency crystal oscillator (HFXT). The internal DCO provides 10 factory-trimmed frequencies up to 16 MHz, and the CPUXV2 core executes instructions at this rate with single-cycle access to FRAM and SRAM - enabling real-time control loops and fast ADC sampling without wait states.
Does the MSP430FR5869IRGZR support hardware encryption?
No, the MSP430FR5869IRGZR does not include dedicated AES or cryptographic acceleration hardware. It provides a random number seed register for software-based RNG algorithms but lacks on-die encryption engines. For secure boot or data-at-rest protection, external ICs or software libraries must be implemented - unlike later MSP430FR59xx or MSP430FR6xx devices that integrate AES-128 modules.
Can the MSP430FR5869IRGZR operate without an external crystal?
Yes, the MSP430FR5869IRGZR can operate using its internal digitally controlled oscillator (DCO) with 10 factory-trimmed frequencies ranging from ~100 kHz to 16 MHz. External crystals (LFXT for RTC, HFXT for high-speed clocks) are optional - the device achieves full functionality, including LPM3.5 RTC operation, only when LFXT is connected to PJ.4/PJ.5.
What debug interface does the MSP430FR5869IRGZR use?
The MSP430FR5869IRGZR uses the two-wire Spy-Bi-Wire (SBW) interface via RST/NMI/SBWTDIO and TEST/SBWTCK pins. This interface supports full JTAG-like debugging - including breakpoints, register inspection, and flash programming - using TI's MSP-FET or compatible tools. No external debug header is required, simplifying board layout and reducing cost.
Is the MSP430FR5869IRGZR pin-compatible with other devices in the FR58xx family?
Yes, the MSP430FR5869IRGZR shares identical pinout and package (48-pin VQFN, RGZ) with MSP430FR5868IRGZR, MSP430FR5867IRGZR, and MSP430FR58671IRGZR. All share the same peripheral mapping and electrical characteristics, enabling hardware reuse across variants - for example, upgrading FRAM capacity from 32KB to 64KB without PCB changes.
