NOR Flash Serial-SPI 3V 512Mbit 512M/256M/128M x 1bit/2bit/4bit 16-Pin SOP-II T/R

The N25Q512A is a 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. Innovative, high-performance, dual and quad input/output instructions enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.
