MSP430FR2632IYQWT Key Features

• 16-bit core with deterministic execution that provides efficient control and low interrupt latency for real-time tasks.
• Nonvolatile FRAM offering fast, write-endurance advantages compared to flash, which matters for frequent data logging and configuration updates.
• Integrated 12-bit ADC with up to 200 ksps throughput for more accurate analog sensing compared to lower-resolution converters.
• Multiple serial interfaces (UART, SPI, I2C) via eUSCI modules to simplify sensor and peripheral integration and reduce external component count.
• Multiple 16-bit timers and DMA support to offload periodic tasks and improve overall energy efficiency.
• Wide operating voltage (1.8?C3.6 V) enables flexible power-rail choices and compatibility with common battery chemistries.
• Compact 32-pin QFN package provides a small PCB footprint while keeping up to 32 accessible I/O pins for system design density.

Typical Applications

• Battery-powered sensor nodes that require frequent nonvolatile data writes and ultra-low standby current for multi-year field life.
• Industrial control endpoints where fast nonvolatile storage and deterministic 16-bit control reduce system latency and simplify firmware updates.
• Portable medical devices needing compact packages, accurate 12-bit ADC measurement, and reliable nonvolatile logging for patient data.
• Smart metering and energy monitors that demand frequent measurements, long-term data retention, and low-power sleep modes for efficiency.

MSP430FR2632IYQWT Advantages vs Typical Alternatives

The device offers a clear advantage when frequent nonvolatile writes or quick configuration updates are required. Its FRAM supports far higher write endurance and lower write energy compared with typical flash-based MCUs. The 16-bit core and integrated peripherals reduce external components and board area versus alternatives that need external memory or ADCs. Low-voltage operation and multiple low-power modes yield lower standby current versus many 32-bit options in the same package, making it ideal for constrained power budgets.

FAQ

What memory type does it use?

The MCU uses nonvolatile FRAM. FRAM provides fast writes, high endurance, and low energy per write compared with flash, which benefits frequent logging and in-field updates.

What is the CPU architecture?

It features a 16-bit RISC architecture common to the MSP430 family. The core offers efficient code density and predictable timing for interrupt-driven and real-time control tasks.

Which serial interfaces are supported?

Serial connectivity is provided through enhanced universal serial communication interfaces (eUSCI), enabling UART, SPI, and I2C links to sensors, radios, and external devices without extra bridging chips.

Is it suitable for low-power designs?

Yes. The device supports multiple low-power modes and operates from 1.8 V to 3.6 V, enabling designs with very low standby current and long battery life in sleep-heavy applications.

What package options exist?

The part is offered in a compact 32-pin QFN package that provides up to 32 accessible I/O points. The small footprint helps reduce PCB area versus larger packaged alternatives.
