MSP430FR6989 in MSP430 Family
The MSP430FR6989 is a 16-bit ultra-low-power microcontroller family from Texas Instruments based on the RISC architecture and integrated Ferroelectric Random Access Memory (FRAM). It is designed for applications requiring high endurance, fast write speeds, and low power consumption. By combining non-volatile storage with the speed and flexibility of RAM, this family enables complex data logging and state retention in battery-operated environments where traditional Flash memory might exceed power budgets or wear out prematurely.
Variants in This Sub-Family
The MSP430FR6989 sub-family variants primarily differ based on their physical package types and temperature ratings. Packaging options include 80-pin and 100-pin LQFP or VQFN configurations, which dictate the number of available GPIOs and LCD segments. While the core architecture and 128KB FRAM capacity remain consistent across the 6989 line, specific ordering codes like IPZ or IPZR denote tray versus tape-and-reel distribution formats.
