GD25VQ40CTIG

Memory IC Overview

The GD25VQ40CTIG is a 4 Mbit NOR flash memory device manufactured by GigaDevice. It features a serial peripheral interface (SPI) with support for dual and quad I/O modes, operating at a maximum clock frequency of 104 MHz. The component utilizes an 8-pin SOP package and supports a supply voltage range from 2.3 V to 3.6 V. It offers a memory organization of 512 k x 8 bits and maintains an active read current of up to 20 mA. The device is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports standard SPI, dual I/O, and quad I/O communication protocols for flexible system integration.
• Provides non-volatile data storage with uniform sector architecture for reliable code execution.
• Operates within a wide industrial temperature range suitable for demanding environments.

Memory IC Applications

• Industrial control systems requiring robust code storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded applications needing fast random access memory

Memory IC Procurement Notes

Verify the specific suffix 'V' indicates the 2.3V minimum voltage rating compared to other variants in the series. Confirm the tube packaging format aligns with assembly requirements. Ensure the manufacturer designation matches Gigadevice Electronics Singapore PTE.LTD. or authorized equivalents. Check for RoHS compliance documentation prior to final procurement decisions.

Memory IC Selection Notes

Select this model when a lower minimum operating voltage of 2.3 V is required compared to standard 2.7 V parts. The 104 MHz speed is sufficient for most general-purpose embedded applications. Consider the SOP-8 package dimensions for PCB layout constraints. Verify compatibility with existing SPI controllers supporting dual/quad modes.

Memory IC Part Context

This part belongs to the GD25VQ40C series of SPI NOR flash memories. It shares architectural similarities with the GD25Q40C but differs in voltage specifications. The series targets cost-sensitive applications requiring reliable non-volatile storage. It complements higher-density options in the broader GigaDevice portfolio.

Memory IC Replacement Considerations

GD25Q40CTIGR serves as a functional alternative with a 2.7 V minimum voltage requirement. GD25D40CTIG offers similar capacity but may differ in interface speed capabilities. Verify pinout compatibility before substituting any variant within the GD25 family.
