Description

GD25VQ40CEIGR is a 4‑Mbit serial flash memory from GigaDevice. It uses SPI-compatible interfaces (Standard SPI, Dual SPI, and Quad SPI) for high-throughput data access. Key points:
- Capacity: 4 Mbit (512 KB)
- Interface: Single, Dual, and Quad I/O SPI
- Voltage: 2.7–3.6 V (3.3 V typical)
- Package: 8-pin, RoHS-compliant
- Performance: fast read up to about 104 MHz; supports 256-byte page programming, 4 KB sectors, 32 KB/64 KB blocks, and chip erase
- Features: Write Enable/Protect mechanisms, status register, and sector/block protection
- Applications: firmware storage and boot code, code shadowing, and other embedded storage needs
In short, GD25VQ40CEIGR is a compact, versatile SPI flash suitable for bootloaders and firmware storage in microcontroller-based designs. If you need exact timing, voltage tolerances, and package details, consult the official datasheet.
