GD25Q64EWIGY

Memory IC Overview

The GD25Q64EWIGY is a 64M-bit (8M x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates within a voltage range of 2.7V to 3.6V and supports standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 133MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It is housed in an 8-WSON package measuring 5x6mm.

Memory IC Feature Summary

• Supports standard, Dual, and Quad SPI modes for flexible data transfer rates
• Includes software and hardware write protection mechanisms via status register bits
• Features advanced security options including unique ID and OTP security registers
• Enables Execute In Place (XiP) operation for direct code execution

Memory IC Applications

• Storing firmware and bootloaders for microcontrollers
• Data storage for IoT devices and embedded systems
• Configuration parameter storage in consumer electronics
• Code execution in place (XiP) applications

Memory IC Procurement Notes

Verify the specific suffix 'WIGY' against official datasheets to confirm the 8-WSON (5x6mm) package type and tape-and-reel or tray packaging details. Ensure compatibility with system voltage requirements of 2.7V to 3.6V. Confirm that the Quad Enable (QE) bit configuration matches the target board design, as it alters pin functions.

Memory IC Selection Notes

Select this component when a compact 8-pin surface-mount package is required for 64M-bit capacity. It is suitable for designs needing high-speed read performance up to 133MHz. Consider the uniform sector architecture for consistent erase granularity. Verify that the host controller supports the necessary SPI modes and dummy cycle configurations for optimal speed.

Memory IC Part Context

This part belongs to the GD25Q64E series of Serial Flash memories from GigaDevice. The series is designed for general-purpose non-volatile storage in embedded applications. The 'E' variant typically denotes enhanced features or specific process nodes compared to earlier generations like the GD25Q64C.

Memory IC FAQ

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set to 1, the WP# and HOLD# pins function as bidirectional I/O pins (IO2 and IO3) to support Quad SPI operations.

What is the purpose of the Dummy Configuration (DC) bit?

The DC bit configures the number of dummy cycles between address output and data output, which is necessary to maintain data integrity at higher clock frequencies.
