Product details
Overview
MSP430FR5967IRGZT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in a 48-pin VQFN package, featuring 32KB nonvolatile FRAM, 1KB RAM, 16-channel 12-bit ADC, RTC with calendar/alarm, and dual eUSCI modules (UART/IrDA/SPI + I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and metering systems requiring long-term data retention without flash wear-out.
For engineers reviewing the MSP430FR5967IRGZT datasheet, MSP430FR5967IRGZT pinout, MSP430FR5967IRGZT application, or MSP430FR5967IRGZT equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (0.25 µA), integrated AES-128/256 coprocessor, capacitive touch I/O support, and 48-pin RGZ package compatibility with energy-harvested embedded designs.
Technical Context
The MSP430FR5967IRGZT implements the CPUXV2 core with 16 general-purpose registers and executes instructions at up to 16 MHz using a flexible clock system comprising DCO (10 factory-trimmed frequencies), LFXT (32-kHz crystal), and HFXT (high-frequency crystal). Its memory architecture unifies program, data, and storage in 32KB FRAM-enabling instant write, radiation resistance, and no erase cycles.
Peripherals include five 16-bit timers (TA0–TA3, TB0), 3-channel DMA, 16-channel analog comparator, CRC16 engine, and dual eUSCI modules: eUSCI_A0/A1 support UART with auto-baud detection and IrDA, while eUSCI_B0 supports I²C with multiple slave addressing and SPI-all operating across all low-power modes including LPM3.5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5969IRGZT | 64KB FRAM, 2KB RAM, same 48-pin RGZ package and peripheral set; adds 32KB FRAM capacity and 1KB RAM over MSP430FR5967IRGZT. | Preferred where extended firmware partitioning, larger OTA update images, or longer local data retention (>2× duration) are required. | Select MSP430FR5969IRGZT when FRAM headroom for future feature expansion or dual-bank firmware is critical; pin-compatible upgrade path. |
| MSP430FR5947IRHA | 32KB FRAM, 1KB RAM, but in 40-pin VQFN (RHA); lacks HFXT oscillator (no PJ.6/PJ.7), reducing max system clock flexibility. | Suitable for cost-sensitive, space-constrained designs where HFXT is unnecessary and 40-pin layout suffices. | Choose MSP430FR5947IRHA for lower-cost, smaller-footprint deployments without high-frequency crystal requirements-requires PCB redesign. |
Compared with MSP430FR5969IRGZT, the MSP430FR5967IRGZT trades FRAM/RAM capacity for identical peripheral integration and ultra-low-power operation in the same 48-pin package; versus MSP430FR5947IRHA, it adds HFXT support and maintains RGZ footprint-making it optimal for scalable, crystal-flexible, and layout-consistent designs.

FAQ
What is the maximum operating frequency of the MSP430FR5967IRGZT?
The MSP430FR5967IRGZT supports a maximum system clock frequency of 16 MHz using its digitally controlled oscillator (DCO) or external HFXT crystal. This frequency is fully operational across the specified voltage range (1.8 V to 3.6 V) and enables real-time signal processing, high-speed UART communication, and responsive capacitive touch scanning without compromising ultra-low-power design goals.
Does the MSP430FR5967IRGZT support hardware-accelerated cryptography?
Yes, the MSP430FR5967IRGZT integrates a dedicated AES-128 and AES-256 hardware coprocessor. This engine performs encryption and decryption independently of the CPU, enabling secure boot, authenticated firmware updates, and encrypted FRAM data storage-critical for compliance in metering and medical applications where MSP430FR5967IRGZT is deployed.
What crystal configurations does the MSP430FR5967IRGZT support for real-time clock operation?
The MSP430FR5967IRGZT supports RTC operation using a 32-kHz crystal connected to PJ.4 (LFXIN) and PJ.5 (LFXOUT). This configuration enables calendar-mode timekeeping with 0.25 µA typical current in LPM3.5. The device does not support RTC operation from VLO or DCO alone-external 32-kHz crystal is mandatory for accurate, ultra-low-power RTC functionality in MSP430FR5967IRGZT.
How many analog input channels does the 12-bit ADC in the MSP430FR5967IRGZT support?
The MSP430FR5967IRGZT features a 12-bit SAR ADC (ADC12_B) with support for up to 16 external analog input channels (A0–A15) plus 2 internal channels (temperature sensor and VREF). Channel selection is software-configurable, and the module includes integrated reference voltages (1.2 V, 2.0 V, 2.5 V), sample-and-hold, and configurable conversion timing-making it suitable for multi-sensor monitoring in MSP430FR5967IRGZT-based systems.
Is the MSP430FR5967IRGZT pin-compatible with other devices in the MSP430FR596x family?
Yes, the MSP430FR5967IRGZT is pin-compatible with MSP430FR5968IRGZT and MSP430FR5969IRGZT in the 48-pin VQFN (RGZ) package. All share identical pinouts, peripheral mappings, and power/ground assignments-allowing drop-in replacement for FRAM capacity scaling (32KB → 48KB → 64KB) without PCB revision, provided HFXT and other peripheral usage aligns with the target variant.
