MSP430FR5994IZVW Technical Specifications

MSP430FR5994IZVW Key Features

• 16-bit CPU with deterministic execution for lower code size and faster interrupt handling compared to 32-bit alternatives in simple control tasks.
• FRAM nonvolatile memory offers fast, byte-write capability and higher write endurance than typical flash, enabling frequent data logging without wear concerns.
• Low-voltage operation from 1.8 V to 3.6 V, which supports wider battery options and extends runtime versus higher-voltage parts.
• Integrated analog front end with a 12-bit ADC that reduces BOM and PCB area compared to discrete analog solutions.
• Rich serial interfaces including UART/SPI/I2C support for flexible connectivity to sensors and external devices.
• 100-pin package delivers many I/O and peripheral options, helping replace multiple smaller devices with one MCU.

Typical Applications

• Low-power data loggers that require frequent nonvolatile writes and long-term retention for sensor readings and event records.
• Battery-powered metering and sensing nodes where energy-efficient CPU modes extend service life and reduce maintenance frequency.
• Industrial control panels that need multiple interfaces and reliable nonvolatile storage for configuration and runtime data.
• Embedded HMI or instrument clusters where compact footprint and many GPIOs support displays, buttons, and communication buses.

MSP430FR5994IZVW Advantages vs Typical Alternatives

The device stands out by combining FRAM endurance and fast writes with a low-power 16-bit core. That mix beats typical flash-based MCUs for frequent-write applications and for faster nonvolatile updates. Operating down to 1.8 V and featuring a 100-pin package, it delivers more I/O and longer battery life than many similar-class alternatives. Developers get simpler data-logger designs, fewer external components, and higher system-level reliability through integrated analog and DMA support.

FAQ

What is the core architecture?

The MCU uses a 16-bit RISC CPU optimized for low power. The architecture minimizes code size and interrupt latency, which benefits energy-sensitive control and monitoring applications.

Is the nonvolatile memory writable in-system?

Yes. The FRAM supports fast, byte-level nonvolatile writes while the system is running. This enables frequent data logging and parameter updates without block erase cycles typical of flash.

Can it run from a single-cell battery?

Operation from 1.8 V to 3.6 V covers single-cell lithium chemistries and many coin or alkaline options. Low-power modes further extend battery life in intermittent sampling or standby use cases.

Does it include built-in ADC?

Yes. A 12-bit ADC is integrated to provide higher-resolution analog measurement without external converters, reducing part count and simplifying PCB routing.

Which package should I choose for many I/Os?

The 100-pin VQFN (IZVW) variant offers the largest I/O and peripheral exposure for this family. It fits designs that require multiple buses, display segments, and numerous sensor inputs.
