MSP430FR5732IRGET Technical Specifications

MSP430FR5732IRGET Key Features

• Single 16-bit RISC core for efficient control and deterministic response times with lower code-size overhead than many 32-bit cores.
• FRAM nonvolatile memory enabling faster write speeds and higher endurance than flash, which reduces write latency in data-logging and configuration storage.
• Integrated 12-bit ADC and multiple timer modules that provide precise analog sensing and deterministic PWM/timing control for motor, lighting, or sensor front ends.
• Multiple eUSCI serial interfaces supporting UART, SPI, and I2C for easy integration with sensors, power-management ICs, and other peripherals.

Typical Applications

• Battery-powered sensor nodes that need frequent, reliable nonvolatile data logging and long service life, while minimizing power draw during sleep cycles.
• Industrial sensing and control systems that require deterministic timing, multi-channel analog acquisition, and robust communications to external buses or sensors.
• Portable medical or measurement instruments that demand accurate ADC performance, frequent calibration storage, and quick nonvolatile updates without long write delays.
• Human-interface devices and control panels that need capacitive or analog sensing, precise timers for debouncing and PWM, and persistent configuration storage.

MSP430FR5732IRGET Advantages vs Typical Alternatives

The device offers lower power operation and faster nonvolatile memory writes compared with flash-based 16-bit or 32-bit microcontrollers. FRAM gives higher endurance for repeated data logging and configuration updates, reducing lifetime wear concerns. With integrated ADC, timers, and multi-protocol serial blocks in a compact 64-pin package, this MCU provides tighter peripheral integration and fewer external components than many alternatives, enabling smaller bills of materials and faster development cycles.

FAQ

What memory type is used?

This microcontroller uses FRAM (ferroelectric RAM) as its nonvolatile program and data memory. FRAM provides fast write performance and high endurance compared with flash memory, making it suitable for frequent updates.

Which serial interfaces are available?

The device includes eUSCI serial modules capable of operating as UART, SPI, and I2C masters or slaves. These interfaces support common peripheral connectivity patterns for sensors, displays, and external memory.

Is the ADC resolution suitable for precision sensing?

Yes. The built-in ADC is a 12-bit converter with multiple input channels. It supports common precision sensing tasks such as temperature measurement, battery monitoring, and analog sensor acquisition.

What is the operating temperature range?

The industrial-grade temperature range covers typical commercial and industrial environments. This ensures reliable operation in factory, outdoor, and battery-powered applications that require extended temperature tolerance.

How does FRAM benefit embedded designs?

FRAM enables near-instant, low-energy nonvolatile writes and a far greater write endurance than flash. This benefits designs that perform frequent configuration saves, event logging, or data buffering without impacting device lifetime.
