Product details
Overview
MSP430FR5867IRGZT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 32KB nonvolatile memory, 1KB RAM, and integrated 12-bit ADC (16-channel), RTC, and five 16-bit timers. It operates from 1.8 V to 3.6 V and delivers 100 µA/MHz active current, targeting battery-powered metering and sensor node applications.
For engineers reviewing the MSP430FR5867IRGZT datasheet, MSP430FR5867IRGZT pinout, MSP430FR5867IRGZT application, or MSP430FR5867IRGZT equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (0.25 µA), 48-pin VQFN package, UART/I²C/SPImulti-protocol eUSCI peripherals, and capacitive touch I/O support without external components.
Technical Context
The MSP430FR5867IRGZT implements the CPUXV2 core with 16 registers and integrates a 32-bit hardware multiplier, 3-channel DMA, and CRC16 engine for deterministic real-time processing. Its clock system includes DCO (10 factory-trimmed frequencies), LFXT (32 kHz crystal), and HFXT (up to 24 MHz) oscillators - all configurable via software-controlled registers.
Peripherals are organized into low-power domains: RTC_B and LPM3.5 operate independently using LFXT; ADC12_B supports up to 16 external analog inputs with internal reference and sample-and-hold; and eUSCI_A0/A1 provide UART/IrDA/SPI while eUSCI_B0 supports I²C/SPI - all accessible in multiple low-power modes with wake-on-event capability.

FAQ
What is the maximum operating frequency of the MSP430FR5867IRGZT?
The MSP430FR5867IRGZT supports a maximum system clock frequency of 16 MHz using the high-frequency crystal oscillator (HFXT) or DCO. This allows real-time execution of metrology algorithms and sensor fusion tasks while maintaining ultra-low power consumption in active mode at 100 µA/MHz.
Does the MSP430FR5867IRGZT support hardware encryption?
No, the MSP430FR5867IRGZT does not include a hardware AES accelerator. It provides a random number seed generator for cryptographic software libraries but relies on firmware-based encryption routines. For hardware-accelerated security, consider MSP430FR59xx series devices with integrated AES256 modules.
Can the MSP430FR5867IRGZT operate from a single 1.8-V supply?
Yes, the MSP430FR5867IRGZT is fully specified to operate from 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including 12-bit ADC operation, RTC_B in LPM3.5, and FRAM read/write - making it ideal for single-cell Li-ion or coin-cell battery systems where voltage regulation headroom is minimal.
How many I²C interfaces does the MSP430FR5867IRGZT have?
The MSP430FR5867IRGZT includes one eUSCI_B0 module that supports I²C communication with multiple slave addressing and clock stretching. It does not contain a second independent I²C interface; additional I²C buses require bit-banged GPIO or external bridge ICs.
Is the MSP430FR5867IRGZT pin-compatible with the MSP430FR5869IRGZT?
Yes, the MSP430FR5867IRGZT is pin-compatible with the MSP430FR5869IRGZT in the 48-pin VQFN (RGZ) package. Both share identical pin assignments, electrical characteristics, and peripheral mappings - differing only in FRAM size (32 KB vs. 64 KB) and SRAM (1 KB vs. 2 KB), allowing drop-in upgrades where memory headroom permits.
