MSP430FR2355 in MSP430 Family
The MSP430FR2355 family by Texas Instruments consists of ultra-low-power microcontrollers based on the 16-bit MSP430 RISC architecture. These devices are notable for integrating 32KB of unified Ferroelectric Random Access Memory (FRAM), combining the speed and endurance of RAM with the non-volatility of flash. They are specifically designed for applications requiring high-precision sensing and robust signal conditioning, leveraging integrated smart analog combos to minimize external component count and power consumption in sensitive instrumentation designs.
Variants in This Sub-Family
Variants within the MSP430FR2355 sub-family primarily differ in packaging options, ranging from 32-pin VQFN to 48-pin LQFP, and temperature grade certifications. While the core 32KB FRAM capacity remains consistent across the '2355' designation, different ordering codes specify reel sizes and tape specifications. Some sister variants like the FR2353 offer reduced memory footprints of 16KB for cost-sensitive implementations while maintaining the same analog peripheral set.
