GD25LQ128DSIGR – Serial NOR Flash – GigaDevice

GigaDevice GD25LQ128DSIGR is a 128 Mbit (16 MB), 1.8V low-voltage SPI NOR Flash memory with Dual/Quad I/O and QPI support, up to 120 MHz, in an 8-pin SOP (208mil) package, tape-and-reel. Industrial temperature -40C to +85C.

The GD25LQ128DSIGR from GigaDevice is a 128 Mbit (16 Mbyte) low-voltage serial NOR Flash memory from the GD25LQ family. Operating from a 1.65V to 2.0V supply (1.8V nominal), it delivers high-speed, low-power non-volatile storage for space-constrained and battery-sensitive embedded designs. The device supports Standard SPI, Dual I/O, Quad I/O and QPI interfaces at clock frequencies up to 120 MHz, making it well suited to code-shadowing, execute-in-place (XIP), boot, and data-logging roles.

The “SIGR” ordering suffix designates the industrial temperature grade (-40C to +85C) in an 8-pin SOP 208mil package, supplied in tape-and-reel packaging. GigaDevice has marked the GD25LQ128D as Not Recommended for New Designs (NRND), which can make ongoing supply challenging for production and service builds that still depend on it.
