Description
GD25LQ64CSIGR is a 64‑Mbit serial flash memory from GigaDevice. It uses SPI (standard, Dual, and Quad I/O modes) and comes in an 8‑pin package (IGR suffix indicates RoHS lead‑free packaging). Operating voltage is typically 2.7–3.6 V. It supports high‑speed read and Quad I/O read, as well as page program writes and erase commands (sector/block/chip erase). It includes a Write Enable Latch, status register, and a deep power‑down mode for low power. Endurance is typical of serial flash (program/erase cycles), making it suitable for firmware/code storage, boot ROM, and data storage in MCUs, microprocessors, and SoCs. For exact timing, command set, pinout, and electrical characteristics, refer to the GD25LQ64CSIGR datasheet.
