Product details
Overview
MSP430FR5968IRGZR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, 12-bit ADC (16-channel), RTC with calendar/alarm, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 1.8 V to 3.6 V and targets energy-constrained sensor nodes and metering systems.
For engineers reviewing the MSP430FR5968IRGZR datasheet, MSP430FR5968IRGZR pinout, MSP430FR5968IRGZR application, or MSP430FR5968IRGZR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (0.25 µA typical), RTC accuracy with 32-kHz crystal, and 48-pin VQFN (7 mm × 7 mm) package compatibility with TI's MSP-TS430RGZ48C development board.
Technical Context
The MSP430FR5968IRGZR integrates a CPUXV2 core with 16 registers, 32-bit hardware multiplier, and 3-channel DMA for efficient signal processing in low-power modes. Its clock system includes DCO (10 factory-trimmed frequencies), VLO, LFXT (32-kHz crystal), and HFXT (up to 16 MHz), enabling precise timing control across active and sleep states.
Peripherals are partitioned into LPM3.5 domain (RTC_B, LFXIN/LFXOUT) and full-power domain (ADC12_B, eUSCI_A0/A1/B0, Timer_B0). Capacitive touch I/O is supported on all pins without external components, and AES256 encryption accelerates secure firmware updates and data logging.

FAQ
What is the maximum operating frequency of the MSP430FR5968IRGZR?
The MSP430FR5968IRGZR supports a maximum system clock frequency of 16 MHz via its factory-trimmed DCO or external HFXT oscillator. This enables real-time signal processing while maintaining ultra-low-power operation in active mode (≈100 µA/MHz). The device also supports lower-frequency sources including VLO (10 kHz) and 32-kHz LFXT for RTC and low-power timing.
Does the MSP430FR5968IRGZR support hardware encryption?
Yes, the MSP430FR5968IRGZR includes a dedicated 128-bit or 256-bit AES security coprocessor. This hardware accelerator performs encryption and decryption independently of the CPU, enabling secure firmware updates, encrypted data logging in FRAM, and authentication protocols without compromising real-time performance or power efficiency.
What package type and dimensions does the MSP430FR5968IRGZR use?
The MSP430FR5968IRGZR uses a 48-pin VQFN package (RGZ suffix) with 7 mm × 7 mm body size and 0.5-mm pitch. It features an exposed thermal pad recommended for connection to DVSS to enhance thermal dissipation and electrical stability in high-density PCB layouts.
Can the MSP430FR5968IRGZR operate from a 1.8-V supply?
Yes, the MSP430FR5968IRGZR operates across a wide supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including FRAM read/write, 12-bit ADC operation, and RTC with 32-kHz crystal - though minimum SVS thresholds must be observed per datasheet Section 5.3 to ensure reliable brownout protection.
How many I²C interfaces does the MSP430FR5968IRGZR support?
The MSP430FR5968IRGZR supports one hardware I²C interface via eUSCI_B0, compliant with standard-mode (100 kbps) and fast-mode (400 kbps) specifications. It includes multiple slave addressing capability and automatic clock stretching, enabling robust communication with sensors, EEPROMs, and other I²C peripherals in resource-constrained systems.
