The SM2258XT is a high-performance SATA 6Gb/s SSD controller ideally suited for cost-effective, small form factor and low power client and industrial storage solutions for PCs, Ultrabooks, Tablet PCs, and other embedded applications. The single-chip, DRAM-less design reduced BOM cost without compromizing performance while enabling 2.5″, 1.8″, slim SATA(MO-297), mSATA(MO-300) and M.2 form factor SSDs. Its ultra-low power consumption effectively extends battery life and optimizes user experience.
The SM2258XT is a complete merchant ASIC/firmware solution supporting 1z nm TLC and 3D NAND from all major NAND suppliers. Leveraging Silicon Motion’s proprietary NANDXtend™ error-correcting code (ECC) technology, the SM2258XT provides a comprehensive data protection and enhances the endurance and retention of TLC NAND, delivering more than three times better durability for TLC SSD.
