The W25Q256JVIM is a 256Mbit (32MB) Serial NOR Flash Memory from Winbond with Standard\/Dual\/Quad SPI and QPI interfaces, operating at 2.7V to 3.6V with 133 MHz clock rate. The 32MB capacity is the largest in the standard 8-pin SPI NOR Flash family, suitable for large firmware images, Linux rootfs, and data logging. The VIM suffix indicates an 8-pin VDFN (WSON) package.<\/p>\n
