GD25LQ128DB2GR – Serial NOR Flash – GigaDevice

The GD25LQ128DB2GR is a GigaDevice 128Mbit (16M x 8) 1.8V Serial NOR Flash from the GD25LQ128D family, supporting Standard/Dual/Quad SPI and QPI at up to 120 MHz in a WSON8 package. This is an NRND, hard-to-find part – request a quote from Pacific Component Xchange.

The GD25LQ128DB2GR is a 128-megabit (128Mbit) Serial NOR Flash memory device from GigaDevice Semiconductor, part of the GD25LQ128D 1.8V SPI NOR Flash family. Organized as 16M x 8 (16 MB), it operates from a low 1.65 V to 2.0 V single supply, making it well suited to power-sensitive, battery-powered, and low-voltage embedded designs. The device supports the industry-standard Serial Peripheral Interface (SPI) plus Dual I/O, Quad I/O, and QPI modes, delivering fast read performance at clock rates up to 120 MHz. The “B2” ordering suffix corresponds to the WSON8 8x6mm package option.

GigaDevice has placed the GD25LQ128D family in a Not Recommended for New Designs (NRND) status. As authorized-distributor stock dries up, Pacific Component Xchange maintains inventory to keep your existing production lines, service builds, and legacy designs running without a costly redesign.
