MSP430FR2632IRGET Technical Specifications

MSP430FR2632IRGET Key Features

• FRAM nonvolatile memory with fast writes and high endurance enables frequent data logging without write-delay penalties.
• 16-bit MSP430 core delivering deterministic control at up to 16 MHz for responsive real-time tasks and energy-efficient processing.
• Integrated analog and serial peripherals including a 12-bit ADC and eUSCI for UART/SPI/I2C, reducing external components and board complexity.
• Low-voltage operation and small package support compact, battery-powered systems with a 1.8?C3.6 V range in a 20-pin VQFN footprint.

Typical Applications

• Battery-powered sensor nodes that require frequent nonvolatile logging and low sleep-mode current for multi-year field operation.
• Industrial control interfaces that need reliable serial communications (UART, SPI, I2C) and deterministic timers for process timing.
• Consumer metering and portable instruments that benefit from fast-write FRAM, compact packaging, and low-voltage operation to extend battery life.
• Data-acquisition front ends that combine a multichannel 12-bit ADC with local FRAM storage for immediate capture and later transfer.

MSP430FR2632IRGET Advantages vs Typical Alternatives

The device offers a distinct advantage where frequent nonvolatile writes are required. Compared with typical flash-based microcontrollers, FRAM provides much faster write times and higher write endurance, reducing system latency and wear concerns. The integrated 12-bit ADC and eUSCI communications minimize external components versus discrete solutions. Lower-voltage operation and a small 20-pin package make it more compact and power efficient than many 32-bit alternatives for simple real-time control tasks.

FAQ

What memory type is used?

The device uses FRAM (ferroelectric RAM) as its main nonvolatile memory. FRAM enables fast, low-energy writes and very high write endurance compared with NOR flash.

What serial interfaces are available?

Communication is handled by eUSCI modules supporting UART, SPI, and I2C modes. These interfaces provide flexible connectivity to sensors, radios, and host processors.

What is the operating voltage range?

The microcontroller operates across a low-voltage range from 1.8 volts up to 3.6 volts, making it suitable for single-cell lithium and other battery-powered systems.

Is the ADC suitable for sensor inputs?

Yes. The on-chip 12-bit ADC supports multiple channels and is intended for typical sensor sampling tasks that require moderate resolution and conversion speed.

Which package should I select for compact designs?

The RGET variant is offered in a 20-pin VQFN package, which balances a small PCB footprint with thermal and routing advantages for compact, low-profile designs.
