GD25Q40CT2GY – Serial NOR Flash – GigaDevice

The GD25Q40CT2GY is a GigaDevice 4Mbit (512K x 8) serial NOR flash memory in an SOP-8 (150mil) package, featuring a Standard/Dual/Quad SPI interface, 2.7V to 3.6V operation, and an extended -40°C to +105°C temperature grade. Now an NRND/hard-to-find part, it is available from Pacific Component Xchange by RFQ.

The GD25Q40CT2GY is a member of GigaDevice’s GD25Q40C family of 3.3V uniform-sector serial NOR flash memory devices. It provides 4 Mbit (4,194,304 bits) of non-volatile storage organized as 512K x 8, accessed through a Serial Peripheral Interface (SPI) that also supports Dual and Quad I/O modes for higher throughput. The device is housed in an industry-standard SOP-8 (150mil) package, making it a convenient drop-in option for compact embedded designs.

Per the GigaDevice ordering scheme, the GD25Q40CT2GY suffix decodes to a SOP8 150mil package (T), an extended -40°C to +105°C temperature grade (2), a Pb-free / halogen-free Green package (G), and tray packing (Y).

Because the GD25Q40C series is now marked Not Recommended for New Designs (NRND) by GigaDevice, the GD25Q40CT2GY can be difficult to obtain through authorized channels. Pacific Component Xchange stocks this device to support repair, maintenance, and end-of-life production needs.
