MSP430FR5959IRHAT Technical Specifications

MSP430FR5959IRHAT Key Features

• 16?bit MSP430 core ?? delivers predictable performance with efficient code density for control tasks.
• FRAM nonvolatile memory ?? allows fast, write?endurance durable storage that reduces latency versus flash.
• Low operating voltage ?? supports 1.8?C3.6 V to enable battery operation and energy?conscious designs.
• Integrated analog and serial peripherals ?? reduces bill of materials by combining ADC, timers, and eUSCI UART/SPI/I2C.

Typical Applications

• Precision battery?powered sensors that require frequent nonvolatile logging and lower write energy than typical flash solutions.
• Industrial control nodes where reduced BOM count and robust low?power sleep modes extend device life in field deployments.
• Portable medical instruments that need reliable nonvolatile storage, precise timers, and multiple serial interfaces for sensors and displays.
• Smart metering and energy monitoring devices that benefit from FRAM endurance and fast write cycles for frequent data commits.

MSP430FR5959IRHAT Advantages vs Typical Alternatives

The device pairs FRAM with a 16?bit core to deliver faster nonvolatile writes and higher endurance than comparable flash?based MCUs. It runs at comparable clock rates??yet often consumes less energy in frequent?write scenarios due to FRAM’s lower write current. Integrated ADC, timers, and multiple eUSCI serial blocks reduce external component count versus discrete solutions. For low?power, write?intensive embedded designs, this part offers better write latency, longer nonvolatile endurance, and fewer supporting parts compared with many flash?based alternatives.

FAQ

What programming tools are supported?

Developers can use TI’s Code Composer Studio or IAR embedded workbench for development. Both tools provide compiler and debugger support and integrate with standard MSP430 debug probes for single?step and flash/FRAM programming.

How does FRAM compare to flash here?

FRAM in this device provides much faster write cycles and higher endurance than flash. That means more frequent nonvolatile writes with less energy per write and longer lifetime for data logging and configuration storage.

What interfaces connect external sensors?

Multiple eUSCI modules provide UART, SPI, and I2C connectivity. These serial interfaces enable direct connection to a wide range of sensors, converters, and external memory devices with minimal external logic.

Is the device suitable for battery operation?

Yes. The supported 1.8?C3.6 V range and low?power MSP430 architecture make it well suited for battery?powered systems. Sleep modes and peripheral autonomy help minimize average current draw in duty?cycled applications.

Where can I find the full datasheet?

The complete datasheet and ordering information are available from the manufacturer’s product pages and authorized distributors. The datasheet lists pinouts, electrical characteristics, timing diagrams, and recommended PCB land patterns for the RHA package.
