MSP430FR5968IRGZT 16-bit FRAM Microcontroller (IRGZT package)

MSP430FR5968IRGZT Overview

The MSP430FR5968IRGZT is a low-power, 16-bit MSP430 microcontroller with non-volatile FRAM for fast writes and high endurance. It combines a compact core with mixed-signal peripherals to handle timing, communication, and sensing tasks. Designers get more battery life and more deterministic write performance versus flash-based parts. For sourcing and component details visit IC Manufacturer.

MSP430FR5968IRGZT Technical Specifications

MSP430FR5968IRGZT Key Features

• Single 16-bit core with deterministic performance for real-time control and lower code density than many 32-bit MCUs.
• FRAM memory enabling fast, frequent non-volatile writes and longer endurance compared to flash, which matters for logged data and configuration storage.
• Low-voltage operation from 1.8 V to 3.6 V for longer battery life and compatibility with common sensor power rails.
• Integrated analog and timing peripherals such as a 12-bit ADC and multiple 16-bit timers to reduce external component count and increase system reliability.

Typical Applications

• Battery-powered sensor nodes that require frequent non-volatile logging and long standby times, where FRAM write speed and endurance reduce power and maintenance.
• Portable instrumentation needing precise timing, 12-bit analog measurement, and low-power sleep modes for higher runtime and smaller batteries.
• Industrial controls where frequent configuration changes must be stored reliably in non-volatile memory without the latency and wear issues of flash.
• Consumer devices that combine UART, SPI, and I2C peripherals with low power draw to support connectivity and sensing in compact form factors.

MSP430FR5968IRGZT Advantages vs Typical Alternatives

This device offers lower active and standby power compared with many 8? or 32?bit controllers in similar roles. Its FRAM provides faster write times and far greater endurance than flash, which reduces maintenance and improves reliability for frequent writes. With a 16?bit core and integrated mixed?signal peripherals, it delivers comparable control capability but in many cases with fewer external components and less energy per operation.

FAQ

What memory type is used?

The device uses ferroelectric RAM (FRAM) as its non-volatile storage. FRAM supports fast, byte?level writes and high endurance, which is useful for frequent parameter updates and data logging without flash write latencies.

What supply voltage is required?

Designed for low-voltage operation, the allowed supply range covers typical sensor and battery rails. Operate the device within the specified 1.8 V to 3.6 V window to ensure correct peripheral and core operation.

How fast does the CPU run?

The 16-bit core runs up to 16 MHz. That provides a balance of deterministic control response and low power draw compared with higher-clocked processors in similar applications.

Which serial interfaces are available?

On-chip enhanced USCI modules support common serial protocols such as UART, SPI, and I2C. These interfaces reduce the need for external protocol bridges and simplify communication with sensors and radios.

Is it suitable for battery-powered systems?

Yes. The combination of low active current, efficient low-power modes, and FRAM for fast non-volatile writes makes this part suitable for battery-operated and energy-harvested systems where long runtime and frequent storage are required.
