GD25LQ64ENIGR

GD25LQ64ENIGR is a 64-Mbit serial flash memory from GigaDevice (GD25LQ family). It provides non-volatile storage for embedded systems, typically used for firmware, bootloaders, and data logging. It uses an SPI-compatible interface (standard SPI, with possible Dual/Quad I/O modes on supported options) and operates from a single supply in roughly 2.7–3.6 V. It supports standard flash operations: Read and Fast Read, Page Program, Sector/Block/Chip Erase, Write Enable/Disable, and power-down, plus memory protection/security features to guard regions of memory. The ENIGR suffix denotes packaging and grade details (usually an 8-pin package with RoHS/industrial-temperature characteristics); exact package type and electrical specs are in the GD25LQ64ENIGR datasheet. Typical use cases include boot memory for microcontrollers, firmware updates, and storage for configuration or data logs. For precise timing, voltages, and package information, refer to the official datasheet.
