GD25LE64ENEGR

Memory IC Overview

The GD25LE64ENEGR is a 64M-bit (8M x 8) Serial NOR Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V. The device supports Standard, Dual, and Quad SPI interfaces, as well as QPI mode, with a maximum clock frequency of 133MHz for fast read operations. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key electrical characteristics include a typical standby current of 10μA and deep power-down current of 0.2μA. The memory organization allows for execute-in-place (XiP) operation.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532Mbits/s in Quad I/O.
• Provides advanced security features including 128-bit Unique ID, Serial Flash Discoverable Parameters (SFDP), and three 1024-byte security registers with OTP locks.
• Offers software and hardware write protection via Block Protect bits and WP# pin, ensuring data integrity against unauthorized modifications.
• Enables Execute In Place (XiP) operation with continuous read wrap functionality to reduce instruction fetch time and fill SoC caches.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring low-voltage operation.
• Embedded systems needing secure boot code execution with hardware write protection.
• Portable consumer electronics powered by low-voltage battery sources.
• Industrial control applications utilizing execute-in-place capabilities for efficient program execution.

Memory IC Procurement Notes

Verify the specific ordering suffix 'ENIGR' against the manufacturer's official datasheet to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with the required 1.65V-2.0V supply voltage and USON8 or SOP8 packaging constraints. Cross-reference the part number with the latest revision history to avoid obsolete versions.

Memory IC Selection Notes

Select this component when a 64M-bit density is required with a strict low-voltage constraint of 1.65V to 2.0V. It is suitable for designs prioritizing high-speed Quad SPI access and robust security features like OTP-locked security registers. Consider the available package options such as USON8 or SOP8 based on board space limitations and thermal requirements.

Memory IC Part Context

The GD25LE64E series belongs to GigaDevice's Uniform Sector Dual and Quad Serial Flash family. This line is designed for applications demanding high performance, low power consumption, and enhanced security. The series supports various densities and voltage ranges, with the LE variant specifically targeting ultra-low voltage environments. It complements other flash products by offering specialized features for secure, low-power embedded storage.

Memory IC Replacement Considerations

Check for GD25LE64ENIGR equivalents within the same voltage range and interface support. Verify if alternative packages like WLCSP or different SOP sizes are acceptable substitutes. Ensure any replacement maintains the 133MHz clock speed and security register features.

Memory IC FAQ

What is the default state of the Quad Enable (QE) bit upon power-up?

The Quad Enable (QE) bit defaults to 0 upon power-up, which enables the WP# and HOLD# pins for their respective functions rather than Quad I/O data transmission.

How does the Hold function operate when QE is set to 1?

When the QE bit is set to 1, the Hold function is disabled, and the HOLD# pin acts as a dedicated data I/O pin (IO3) instead of a hold input.

What commands are used to switch between Standard SPI and QPI modes?

The 'Enable QPI' command (38H) switches the device to QPI mode, while the 'Disable QPI' command (FFH) returns it to Standard/Dual/Quad SPI mode.
