Winbond QspiNAND Flash Memory
Winbond QspiNAND Flash Memory is high-performance, low-power memory built with Single-Level Cell (SLC) memory technology and implementing 1-bit Error Correction Code (ECC) on all read and write operations. The integrated ECC detects and corrects errors and enables contiguous good memory (bad block management). This feature offloads these functions from an external controller. The QspiNAND Flash Memory also supports Executive-in-Place (XiP) functionality, in which an SoC or processor executes application code directly from the external flash memory without shadowing it to DRAM.
Winbond QspiNAND Flash Memory supports a dual-quad I/O interface to accommodate higher storage density and data transfer rates up to 166MB/s. These devices also allow for single, dual, and quad I/O for maximum flexibility. This memory is offered in SOIC-16, TFBGA-24, WLCSP-48, and WSON-8 packages. These devices are available in industrial-grade and extended-temperature automotive-grade versions operating at up to 105°C.
