GD25Q64ESIGY

Memory IC Overview

The GD25Q64ESIGY is a 64 Mbit NOR flash memory IC manufactured by GigaDevice. It supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 133 MHz. The device operates within a voltage range of 2.7 V to 3.6 V and features an 8M x 8 organization. It utilizes an 8-SOP package.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface (SPI) operations for flexible data transfer rates.
• Includes hardware and software write protection mechanisms with top/bottom block protection capabilities.
• Features advanced security options including a unique 128-bit ID and Serial Flash Discoverable Parameters (SFDP).
• Allows execute-in-place (XiP) operation to reduce instruction fetch latency.

Memory IC Applications

• Firmware storage in embedded systems
• Code execution in place (XiP) applications
• Data logging and configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'Y' against official manufacturer documentation to confirm package dimensions and tape-and-reel specifications. Confirm moisture sensitivity level (MSL) ratings prior to PCB assembly. Ensure compatibility with existing system voltage requirements of 2.7V to 3.6V.

Memory IC Selection Notes

Select this component when high-speed read performance via Quad SPI is required alongside robust data protection features. Consider the 8-SOP package constraints for board space. Verify that the host controller supports the necessary command set for dual and quad I/O operations.

Memory IC Part Context
