MSP430FR5949 in MSP430 Family
The MSP430FR5949 family, manufactured by Texas Instruments, is a series of ultra-low-power 16-bit RISC microcontrollers featuring integrated Ferroelectric Random Access Memory (FRAM). Designed for high-efficiency data logging and sensing, these MCUs combine the speed and endurance of SRAM with the non-volatility of Flash. They are optimized for battery-operated systems where power consumption, fast wake-up times, and high write endurance are critical for maintaining system longevity and data integrity in harsh operating environments.
Variants in This Sub-Family
Variants within the MSP430FR5949 sub-family primarily differ based on their physical packaging and pin counts, such as the 40-pin VQFN (RHA) or 48-pin VQFN (RGZ) options. While the core 64KB FRAM and 2KB SRAM remain consistent, specific part number suffixes like 'R' or 'T' denote tape-and-reel or tray shipping configurations, ensuring compatibility with different assembly line requirements.
