GD25Q64CZIGY – Serial NOR Flash – GigaDevice

The GigaDevice GD25Q64CZIGY is a 64Mbit (8MB) 3.3V Serial NOR Flash with Standard/Dual/Quad SPI, supplied in a TFBGA-24 (6×4 ball array) package, industrial temperature grade, in tray packing.

The GD25Q64CZIGY is a 64M-bit (8,192K-byte) Serial NOR Flash memory from GigaDevice, part of the widely deployed GD25Q “C” generation family. It provides a Standard, Dual, and Quad SPI interface with a single 2.7V to 3.6V power supply, making it well suited for code-shadowing, boot, and data-storage roles in embedded systems. This specific orderable variant is supplied in the TFBGA-24 (6×4 ball array) package at industrial temperature grade and in tray packing.

Decoding the GigaDevice part number: GD25 = SPI interface flash, Q = 3V 4KB uniform-sector series, 64 = 64Mb density, C = C version, Z = TFBGA24 package, I = industrial (-40°C to +85°C), G = Pb-free & halogen-free green package, and Y = tray packing.
