SM3255

Mobile Storage Zoom Family SM3255 USB2.0 Single-Channel Flash Controller Overview The SM3255 is a USB Flash drive controller that combines high compatibility and performance to support single-channel MLC and TLC NAND-type Flash memory in one chip. Based on 0.153μm fabrication technology and low-power consumption considerations, the SM3255 complies with USB2.0 power specifications for bus-powered devices. In conjunction with USB2.0 Flash drive applications, the SM3255 supports high capacity (up to 4 Flash components), “write protection” functionality, PC bootup from a USB2.0 Flash drive, password protection, and secured partitioning functions. The SM3255 controller delivers an extremely reliable, high data transfer rate through an 13/24/48-bit ECC engine to reduce TLC Flash read/write disturbance errors. Combining a 5-3.3V regulator and power-onrest feature, the SM3255 maximize efficiency and reduces overall costs. The SM3255 is available in 40pin QFN, 44-pin LGA and 48-pin LQFP packages with a manufacturing-ready turnkey solution.
