GD25LQ80ETEGR

Memory IC Overview

The GD25LQ80ETEGR is an 8M-bit (1M x 8) Serial NOR Flash memory IC from the GD25LQ series, manufactured by GigaDevice. It supports Standard SPI, Dual I/O, Quad I/O, and QPI interfaces with a maximum clock frequency of 133 MHz. The device operates on a single power supply voltage ranging from 1.65V to 2.0V. 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 1μA. The component ensures data integrity through a minimum endurance of 100,000 Program/Erase cycles and 20-year data retention.

Memory IC Feature Summary

• Supports high-speed data transfer via Dual I/O up to 266 Mbits/s and Quad I/O/QPI up to 532 Mbits/s.
• Provides flexible software and hardware write protection mechanisms including block protect bits and WP# pin control.
• Integrates advanced security features such as 128-bit Unique ID and three 3x1024-byte Security Registers with OTP locks.
• Enables Execute In Place (XiP) operation with continuous read capabilities to reduce instruction fetch latency.

Memory IC Applications

• Code storage for microcontrollers and system-on-chip (SoC) architectures requiring XIP functionality.
• Data logging and configuration storage in industrial and consumer electronic devices.
• Firmware storage for IoT modules and embedded systems operating within low-voltage constraints.

Memory IC Procurement Notes

Verify the specific package suffix 'ET' corresponds to the required footprint, typically WSON8 or SOP8, against your PCB design requirements. Confirm that the voltage range of 1.65V to 2.0V aligns with your system's power rail specifications. Ensure that the Quad Enable (QE) bit configuration in the status register matches your controller's interface mode settings for optimal performance.

Memory IC Selection Notes

Select this component when a compact 8M-bit capacity is needed with support for high-speed Quad and QPI modes. It is suitable for designs requiring low power consumption during standby and deep power-down states. Consider this part if hardware write protection via the WP# pin is necessary alongside software-based block protection schemes for critical data segments.

Memory IC Part Context

This device belongs to the GD25LQ family of dual and quad serial flash memories designed for uniform sector operations. The GD25LQ80E variant specifically offers 8M-bit density optimized for applications needing fast page programming and block erase speeds. It shares architectural similarities with other members of the GD25LQ series but differs in density and specific package options available for the ETEGR designation.

Memory IC FAQ

How does the Quad Enable (QE) bit affect the HOLD# and WP# pins?

When the QE bit is set to 1, the HOLD# and WP# pins function as bidirectional I/O pins (IO3 and IO2) for Quad SPI operations, disabling their dedicated hold and write-protect functions.

What is the default state of the device upon power-up regarding interface mode?

Upon power-up, the device defaults to Standard/Dual/Quad SPI mode. It must be explicitly switched to QPI mode using the Enable QPI command if that interface is desired.
