GD25LQ80EEIGR

Memory IC Overview

The GD25LQ80EEIGR is an 8M-bit (1M x 8) SPI NOR flash memory IC manufactured by GigaDevice. It supports Standard, Dual, Quad SPI, 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 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 modes 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 identification 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 architectures
• Firmware and boot code storage in embedded systems
• Data logging and configuration parameter storage
• Audio and video file storage in consumer electronics

Memory IC Procurement Notes

Verify the specific package variant against the ordering suffix 'EIGR', which corresponds to the USON8 (3x2mm) package. Confirm that the required operating voltage aligns with the 1.65V to 2.0V range specified for this low-voltage series. Ensure compatibility with the host controller's SPI interface modes, particularly if utilizing Quad or QPI operations which require the Quad Enable bit to be set.

Memory IC Selection Notes

Select this component when a low-voltage (1.65V-2.0V) SPI NOR flash solution is required for space-constrained designs due to its compact USON8 packaging. It is suitable for applications demanding high read speeds up to 133 MHz and robust data protection features. Consider this part over higher voltage variants if the system power rail strictly limits operation below 2.7V.
