GD25VQ40CSIGR

Memory IC Overview

The GD25VQ40CSIGR is a 4 Mbit (512 K x 8) SPI NOR flash memory manufactured by GigaDevice. It operates within a supply voltage range of 2.3 V to 3.6 V and supports a maximum clock frequency of 104 MHz. The device features an active read current of up to 20 mA and is housed in an 8-USON (2x3) package with exposed pads. It is designed for industrial temperature ranges, functioning between -40°C and +85°C.

Memory IC Feature Summary

• Supports Dual and Quad I/O SPI interfaces for high-speed data transfer
• Uniform sector architecture for flexible block protection
• Industrial-grade reliability across extended temperature ranges

Memory IC Applications

• Industrial control systems requiring robust code storage
• Consumer electronics firmware storage
• Embedded applications needing non-volatile data retention

Memory IC Procurement Notes

Verify the specific suffix 'IGR' against official datasheets to confirm the 8-USON package type and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints for the 2x3 mm outline. Confirm end-of-life status if applicable, as some variants in this series may be marked as not recommended for new designs.

Memory IC Selection Notes

Select this component when a small form factor is required alongside standard SPI NOR capabilities. The 8-USON package offers space savings compared to SOP-8 alternatives. Verify that the 2.3 V minimum operating voltage aligns with the system's power rail stability under all load conditions.

Memory IC Part Context

This part belongs to the GD25VQ40C series, which provides uniform sector sizes for consistent erase operations. It is distinct from the GD25VE40C series, which typically utilizes an SOP-8 package. The Q-series designation indicates support for Quad I/O modes, enhancing throughput over standard SPI.

Memory IC Replacement Considerations

GD25VQ40CEIGR: Same capacity and interface but in an 8-XFDFN package; verify footprint compatibility.
