NOR Flash Serial-SPI 3V/3.3V 256Mbit 32M x 8bit 32M x 8bit 16-Pin SOP2 Tube

The N25Q256A is the first high-performance multiple input/output serial Flash memory device manufactured on 65nm NOR technology. It features execute-in-place (XIP) functionality, advanced write protection mechanisms, and a high-speed SPI-compatible bus interface. The innovative, high-performance, dual and quad input/output instructions enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.
