Product details
Overview
MSP430FR5869IRGZT 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 sensor nodes and metering systems requiring nonvolatile memory endurance and sub-µA standby current.
For engineers reviewing the MSP430FR5869IRGZT datasheet, MSP430FR5869IRGZT pinout, MSP430FR5869IRGZT application, or MSP430FR5869IRGZT equivalent, key selection criteria include FRAM write endurance (10¹⁵ cycles), LPM3.5 RTC current (0.25 µA typical), 48-pin VQFN package compatibility, and integrated capacitive touch I/O support without external components.
Technical Context
The MSP430FR5869IRGZT implements the CPUXV2 16-bit RISC core with hardware multiplier and three-channel DMA, enabling deterministic real-time processing in energy-constrained environments. Its flexible clock system includes DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (up to 24 MHz) oscillators - with RTC_B module enabled only when LFXT is active.
Peripherals are tightly coupled to low-power operation: five 16-bit timers (including Timer_B with seven capture/compare registers), 16-channel analog comparator, and eUSCI_A0/A1 (UART/IrDA/SPI) plus eUSCI_B0 (I²C/SPI). All I/O pins support capacitive touch sensing and edge-selectable wake-up from LPMx.5 modes.

FAQ
What is the maximum operating frequency of the MSP430FR5869IRGZT?
The MSP430FR5869IRGZT supports up to 16 MHz CPU clock frequency using the high-frequency crystal oscillator (HFXT) or DCO. When configured with an external 24-MHz HFXT, the system clock (MCLK) may be prescaled to deliver 16 MHz to the CPU while maintaining peripheral timing compliance per the device's electrical specifications.
Does the MSP430FR5869IRGZT support hardware encryption?
No, the MSP430FR5869IRGZT does not include a hardware AES engine. Encryption must be implemented in software or via external co-processors. For integrated AES-128 support, consider the pin-compatible MSP430FR5969IRGZT, which shares the same 48-pin VQFN package and FRAM architecture.
Can the MSP430FR5869IRGZT operate from a single 1.8-V supply?
Yes, the MSP430FR5869IRGZT is fully specified to operate from 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including 16-bit CPU execution, 12-bit ADC conversion, FRAM read/write, and real-time clock operation - enabling direct integration with low-voltage energy harvesters and coin-cell batteries.
How many capture/compare registers does the Timer_B module have on the MSP430FR5869IRGZT?
The Timer_B module (TB0) on the MSP430FR5869IRGZT has seven capture/compare registers. This is confirmed in the device comparison table and functional block diagram, enabling complex PWM generation, input capture for frequency measurement, and precise timing control across multiple independent channels.
Is the RTC_B module available on the MSP430FR5869IRGZT?
Yes, the RTC_B module is available on the MSP430FR5869IRGZT and requires connection of a 32.768-kHz crystal to PJ.4 (LFXIN) and PJ.5 (LFXOUT). The RTC_B supports calendar mode, alarm interrupts, and calibration - and operates in LPM3.5 with only 0.25 µA typical current draw.
