GD25B512MEY2GY – Serial NOR Flash – GigaDevice

The GigaDevice GD25B512MEY2GY is a 512Mbit (64M x 8) SPI NOR Flash memory in a WSON-8 (8x6mm) package, supporting Standard/Dual/Quad I/O, QPI and DTR modes at up to 133 MHz with a 2.7V-3.6V supply. Available now for RFQ at Pacific Component Xchange.

The GigaDevice GD25B512MEY2GY is a high-density 512 Mbit (64M x 8) Serial NOR Flash memory from the GD25B512ME family, designed for code storage and execute-in-place (XIP) applications in space-constrained embedded systems. It delivers a flexible SPI interface supporting Standard (Single I/O), Dual I/O, Quad I/O, QPI and Double Transfer Rate (DTR) operation at a maximum clock frequency of 133 MHz, making it well suited for fast boot and high-throughput firmware retrieval. Packaged in a compact WSON-8 (8x6mm) surface-mount form factor, the device operates from a single 2.7V-3.6V supply across the industrial -40 C to +85 C temperature range.
