GD25WQ40ETIGR

Memory IC Overview

The GD25WQ40ETIGR is a 4 Mbit Serial NOR Flash memory manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 104 MHz. The device operates on a single power supply voltage ranging from 1.65 V to 3.6 V. It features uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. The memory organization consists of 512K pages of 256 Bytes each. It includes hardware and software write protection, security registers, and a unique ID.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 416 Mbits/s in Quad I/O mode.
• Provides comprehensive data protection via software block protect bits, hardware WP# pin control, and one-time programmable security registers.
• Enables Execute In Place (XiP) operation with high-speed read commands and continuous read with wrap functionality to reduce latency.
• Features low power consumption with typical standby current of 11 μA and deep power-down current of 0.1 μA.

Memory IC Applications

• Firmware storage in embedded systems requiring XIP capability
• Code execution storage for microcontrollers and SoCs
• Data logging applications with frequent write cycles
• Consumer electronics firmware updates

Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the SOP-8 150mil package and tape & reel packaging as documented in the manufacturer's ordering information. Confirm that the component meets the required industrial temperature range specifications if applicable to your design environment. Ensure compatibility with the host controller's SPI interface voltage levels.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity is required with support for Quad SPI operations at speeds up to 104 MHz. It is suitable for designs needing robust write protection mechanisms including top/bottom block protection and security register locking. Consider the wide voltage range of 1.65 V to 3.6 V for low-power or variable supply applications.

Memory IC Part Context

This part belongs to the GD25WQ series of Uniform Sector Dual and Quad Serial Flash memories. It shares architectural similarities with the GD25WQ20E but offers double the density. The series is designed for applications requiring high reliability, fast program/erase speeds, and flexible protection schemes within a compact surface-mount package.

Memory IC Replacement Considerations

GD25WQ20ETIGR: Offers 2 Mbit capacity with similar interface and protection features. GD25Q40ETIGR: Offers 4 Mbit capacity but operates on a 2.7 V to 3.6 V supply range, lacking the 1.65 V lower bound.
