GD25LF64ENEGR

Memory IC Overview

The GD25LF64ENEGR is a 64M-bit (8192K-byte) uniform sector serial flash memory supporting Standard, Dual, Quad SPI, QPI, and DTR modes. It operates on a single 1.65V to 2.0V supply with 166MHz fast read clock. Key performance metrics include 0.4ms typical page program time, 40ms sector erase, and 10μA standby current. It features 100,000 P/E cycles, 20-year data retention, and 128-bit unique ID.

Memory IC Feature Summary

• Supports high-speed data transfer via Dual I/O (332Mbit/s), Quad I/O (664Mbit/s), and DTR Quad I/O (832Mbit/s) interfaces.
• Provides flexible software write protection for top/bottom blocks and status register lock-down options.
• Includes advanced security features such as 128-bit unique ID and three 1024-byte OTP security registers.
• Enables Execute In Place (XiP) operation with continuous read wrap functionality to reduce latency.

Memory IC Applications

• Firmware storage in embedded systems requiring low voltage operation
• Code execution from flash (XiP) in microcontroller-based designs
• Data logging and configuration storage with security register protection
• Portable electronic devices utilizing single-supply power architectures

Memory IC Procurement Notes

Verify the specific package variant (SOP8, USON8, or WSON8) matches the design footprint. Confirm the voltage range (1.65-2.0V) aligns with system power rails. Ensure the QE bit default state is compatible with the host controller's initialization sequence. Check for any special order requirements regarding Status Register Protection bits if permanent lock-down is needed.

Memory IC Selection Notes

Select this component for applications requiring uniform sector architecture and high-speed DTR Quad I/O access. It is suitable for systems needing robust data retention and endurance specifications. Consider the available package options for space-constrained PCB layouts. Verify compatibility with standard SPI controllers that support Quad and DTR modes.

Memory IC Part Context

The GD25LF64E series is part of GigaDevice's uniform sector serial flash family. The 'ENEGR' suffix indicates specific packaging and environmental compliance attributes defined by the manufacturer. This device competes in the low-voltage, high-density serial NOR flash market segment.

Memory IC Replacement Considerations

Check datasheets for other GD25LFxxE variants with matching voltage ranges and pinouts. Verify command set compatibility for seamless integration. Ensure physical package dimensions match existing board layouts when substituting.

Memory IC FAQ

Can the Quad Enable (QE) bit be changed?

No, the QE bit is permanently set to 1 by default and cannot be changed.

What is the default mode after power-up?

The device defaults to Standard/Dual/Quad SPI mode upon power-up or reset.

How are security registers protected?

Security registers can be locked using One-Time Programmable (OTP) LB bits in the status register, making them read-only permanently once set.
