GD25Q128 128M-bit (16M-byte) Serial NOR Flash Memory IC — GigaDevice SPI/Quad SPI

The GD25Q128 from GigaDevice is a 128M-bit (16M-byte) 3V serial NOR Flash memory with standard, dual, and quad SPI interfaces up to 120MHz. It is engineered for high-density firmware and data storage in embedded and industrial systems.

Product Overview

The GD25Q128 offers a scalable, low-pin-count non-volatile storage solution with 65,536 pages of 256 bytes. It serves as a dependable code-storage device for microcontrollers, SoCs, and FPGA configuration, where consistent supply and drop-in 8-pin compatibility matter.

Quad SPI read capability shortens boot and code-fetch latency, while the uniform 4KB sector and 32/64KB block structure supports OTA updates and robust file-system layering. Its wide operating-voltage and temperature ranges suit industrial environments.
