GD25WQ32EEIGR

Memory IC Overview

The GD25WQ32EEIGR is a 32M-bit (4M x 8) 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 ranging from 1.65V to 3.6V and features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as a 128-bit Unique ID and three 1024-byte Security Registers with OTP locks.

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 hardware and software write protection mechanisms including block protect bits and status register locking.
• Integrates advanced security features including a unique 128-bit identifier and one-time programmable security registers.
• Enables Execute In Place (XiP) operations with continuous read capabilities to reduce system latency.

Memory IC Applications

• Firmware storage for microcontrollers and embedded systems
• Code execution in place (XiP) applications
• Consumer electronics requiring non-volatile code storage
• Industrial control systems needing reliable data retention

Memory IC Procurement Notes

Verify the specific package variant (USON8 3x2mm or USON8 3x4mm) matches the design footprint, as the 'E' suffix indicates the package type. Confirm voltage range compatibility (1.65V-3.6V) with the target system's power rails. Ensure the Quad Enable (QE) bit configuration aligns with the host controller's SPI interface capabilities before finalizing the order.

Memory IC Selection Notes

Select this component for designs requiring high-speed Quad SPI access and robust data protection features. The 32M-bit capacity suits complex firmware requirements. Consider the operating temperature range (-40°C to 85°C) for environmental suitability. Verify that the host system supports the necessary dummy cycle configurations for optimal performance at 104 MHz.

Memory IC Part Context

This part belongs to the GD25WQ series of Dual and Quad Serial Flash memories from GigaDevice. It shares architectural similarities with other devices in the family but is distinguished by its 32M-bit density and specific package options. The series is designed for applications demanding high performance, low power consumption, and enhanced security features in a compact form factor.
