MSP430FR6989IPZR Technical Specifications

MSP430FR6989IPZR Key Features

• FRAM-based nonvolatile memory for near-instant writes and >10x higher write endurance than typical embedded flash.
• Low-power MCU core that reduces active and standby energy, which matters in battery-powered and energy-harvested systems.
• Integrated 12-bit ADC and timers to simplify sensor interfaces and motor control without extra external components.
• Flexible serial interfaces (UART/SPI/I2C) for easier integration with external sensors, displays, and radios.

Typical Applications

• Battery-powered sensor nodes and wireless endpoints where low standby current and faster FRAM writes extend field lifetime and maintenance intervals.
• Industrial monitoring controllers that require reliable nonvolatile storage and frequent parameter updates without impairing endurance.
• Human-machine interfaces and capacitive-touch controls where integrated touch support and low-power sleep modes improve usability and energy efficiency.
• Portable medical and consumer devices that need deterministic firmware updates, robust data logging, and compact mixed-signal peripherals on a single chip.

MSP430FR6989IPZR Advantages vs Typical Alternatives

The FRAM architecture provides faster write times and much higher write endurance than similar flash-based MCUs. This gives designers a clear advantage for frequent data logging and in-field parameter tuning. The 16?bit MSP430 core delivers lower active power than many 32?bit alternatives at similar task levels. The integrated 12?bit ADC, multiple timers, and serial interfaces reduce board count versus discrete solutions, improving reliability and lowering BOM cost.

FAQ

What memory type does it use?

The device uses FRAM (ferroelectric RAM) as its nonvolatile memory. FRAM provides faster writes, lower energy per write, and higher endurance than traditional embedded flash memory.

What supply voltage is required?

It operates across a low-voltage range, typically from 1.8 volts up to about 3.6 volts, allowing compatibility with common battery chemistries and regulated power rails in portable systems.

What analog peripherals are available?

On-chip analog resources include a 12-bit ADC for multi-channel sampling, comparator functions, and support useful for sensor front-ends and precision measurement tasks without extra ADC chips.

What communications can it handle?

Integrated eUSCI modules support standard serial protocols such as UART, SPI and I2C. These interfaces enable direct connection to sensors, memory, and wireless modules with minimal external components.

Is it suitable for low-power designs?

Yes. The processor core and peripheral set include multiple low-power modes and features designed to minimize active and sleep currents, making it well suited for battery-powered and energy-harvested applications.
