GD25B127DSIG – Serial NOR Flash – GigaDevice
The GigaDevice GD25B127DSIG is a 128M-bit (16M-byte) 3.3V serial NOR Flash memory with Standard/Dual/Quad SPI interface in an 8-lead SOP (208mil) package, industrial temperature grade. Available now for RFQ from Pacific Component Xchange.
The GD25B127DSIG from GigaDevice is a 128M-bit (16,384K-byte) serial NOR Flash memory belonging to the GD25B family of 3.3V SPI Flash devices. It supports Standard, Dual, and Quad SPI operation and is housed in an 8-lead SOP package (208mil), making it a popular choice for code-shadowing, boot, and firmware-storage applications in cost-sensitive and space-constrained embedded designs.
The device is organized with a flexible uniform-sector architecture (4K-byte sectors and 32K/64K-byte blocks) and provides a rich command set including Dual and Quad I/O fast read, Quad Page Program, program/erase suspend-resume, and Execute-In-Place (XIP) support. It also integrates advanced security features such as a 128-bit unique device ID and three 1024-byte OTP-lockable security registers.
