256 Mbit NOR Flash for embedded code and data storage
It uses a standard SPI interface with Quad I/O support, clocked at 80 MHz, for fast read and program operations. The memory is non-volatile, rated for the industrial temperature range of -40°C to 105°C, and operates from a single 2.7 V to 3.6 V supply. Typical applications include firmware storage for execute-in-place (XIP) in embedded processors, configuration data in networking gear, and code shadowing in FPGA-based systems.
80 MHz Quad I/O — throughput for XIP and fast boot
The SPI Quad I/O interface at 80 MHz uses four data lines for read operations.
