MSP430FR5729IDA 16-bit FRAM Microcontroller (IDA package)

MSP430FR5729IDA Overview

The MSP430FR5729IDA is a low-power, 16-bit microcontroller in the FRAM-based MSP430 family designed for embedded control and sensor interfacing. It combines non-volatile FRAM memory for fast writes and high endurance with a compact peripheral set that targets battery-powered and real-time applications. Designers benefit from faster code updates, lower power in retention modes, and tighter integration versus typical flash-based microcontrollers.

MSP430FR5729IDA Technical Specifications

MSP430FR5729IDA Key Features

• FRAM-based non-volatile memory for near-instant writes and far higher endurance than flash, which reduces firmware update time and extends data-logging life.
• 16-bit ultra-low-power core that balances processing throughput and energy consumption, enabling longer battery life compared with many 8-bit alternatives.
• Integrated analog and serial peripherals such as a 12-bit ADC and multi-mode eUSCI modules for UART, SPI, and I2C, simplifying sensor interfacing and system integration.
• Small 64-pin package that provides a denser pin count and more I/O than typical 28?C48 pin MCUs while keeping PCB area competitive for compact industrial designs.

Typical Applications

• Battery-powered sensor nodes requiring frequent non-volatile data writes and real-time sampling, where faster write speeds and endurance cut maintenance intervals by years.
• Industrial control panels that need reliable low-power operation and multiple serial interfaces for communication with external modules and sensors over SPI or I2C buses.
• Portable medical devices where low supply current, deterministic wake-up, and robust data retention across power cycles are critical for patient safety and regulatory compliance.
• Energy metering and data-logging systems that demand high non-volatile write endurance for frequent event records and comparably lower power draw than flash-based designs.

MSP430FR5729IDA Advantages vs Typical Alternatives

The FRAM memory in this device yields faster write speeds and dramatically higher endurance compared to flash-based microcontrollers, translating to fewer system constraints and lower field service costs. Its 16-bit MSP430 core delivers better code density and lower active/standby power than many 32-bit alternatives in low-throughput roles. With integrated 12-bit ADC and multi-protocol serial modules, the device reduces external components and BOM count while supporting reliable, low-power sensor interfaces and real-time control.

FAQ

What memory type does it use?

This microcontroller uses FRAM (ferroelectric RAM) for non-volatile program and data storage, offering faster writes and higher endurance than flash memory commonly used in other MCUs.

What supply voltages are supported?

The device operates across a low-voltage range suitable for battery-powered systems, allowing designs to run reliably between 1.8 V and 3.6 V without external voltage translation in many cases.

Is it suitable for battery-powered designs?

Yes. The 16-bit MSP430 core and FRAM architecture are optimized for ultra-low-power operation, providing low active and standby currents that extend battery life versus higher-power alternatives.

Which serial interfaces are available?

On-chip enhanced USCI (eUSCI) modules provide flexible UART, SPI, and I2C connectivity, enabling direct interfacing to sensors, radios, and external memory devices with fewer external components.

What package should I choose for compact boards?

The IDA suffix indicates a 64-pin LQFP package that balances pin count and PCB area, offering more I/O than small QFN parts while remaining suitable for compact industrial and portable boards.
