GD25D10CKIGR

GD25D10CKIGR is GigaDevice’s GD25D10C 1-Mbit serial SPI flash memory in an 8-pin package. It provides non-volatile storage for embedded systems, accessible via a standard SPI interface. Organization is 1 Mbit (128 KB) with typical flash operations: Read, Page Program (256-byte pages), Sector/Block Erase, and Chip Erase, plus Write Enable/Disable and status monitoring. It supports low-power standby and operates from a single supply (commonly around 2.7–3.6 V; often 3.3 V). The suffix “KIGR” usually indicates a specific option set, typically industrial temperature range and RoHS-compliant packaging. For exact electrical characteristics, timing, sector layout, and packaging details, refer to the GD25D10C/GD25D10CKIGR datasheet and product specification sheets.
