📖 Product Overview
The GD25Q40ETIGR is a 4,194,304‑bit (4Mbit) Serial NOR Flash memory device from GigaDevice Semiconductor, organised as 524,288 words × 8 bits (512K x 8). It is part of the GD25Q40E series, offering a high‑performance, low‑pin‑count, and power‑efficient non‑volatile storage solution for code and data storage applications in embedded systems, industrial control, automotive electronics, and consumer devices.
The device operates over a supply voltage range of 2.7V to 3.6V and supports Standard SPI, Dual SPI, and Quad SPI interfaces, providing flexible bus width configurations. It achieves a maximum clock frequency of 133 MHz, enabling fast read operations and efficient instruction execution directly from the flash memory (execute‑in‑place – XIP). In Quad I/O mode, the device can achieve data transfer rates of up to 532 Mbit/s, significantly improving system throughput.
The GD25Q40ETIGR is housed in a standard 8‑pin SOP (150 mil) package, making it widely compatible with existing PCB footprints. It is fully RoHS compliant, lead‑free, and supports a minimum of 100,000 program/erase cycles with 20 years of data retention, ensuring long‑term reliability in industrial and consumer applications.
