GD25LQ64EQEGR

Memory IC Overview

The GD25LQ64EQEGR is a 64 Mbit NOR flash memory integrated circuit manufactured by GigaDevice. It utilizes an SPI interface with Quad I/O support and operates at a maximum clock frequency of 166 MHz. The device functions within a supply voltage range of 1.65 V to 2 V. It is housed in an USON-8 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface communication with quad input/output capabilities for efficient data transfer.
• Designed for operation across an extended industrial temperature range suitable for demanding environments.
• Utilizes a compact USON-8 surface-mount package for space-constrained board layouts.

Memory IC Applications

• Industrial control systems requiring wide temperature tolerance
• Automotive embedded applications
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix 'QE' against official datasheets to confirm the exact package type and temperature grade, as variations exist within the GD25LQ64 series. Confirm RoHS compliance status and ensure the intended application aligns with the 1.65V to 2V supply voltage requirements. Cross-reference the manufacturer's latest documentation for any updates on lead times or end-of-life notices.

Memory IC Selection Notes

Select this component when a low-voltage 1.8V NOR flash with high-speed performance is required. The 166 MHz clock speed offers faster read access compared to standard SPI devices. Ensure the design accommodates the USON-8 footprint and that the thermal environment remains within the specified -40°C to +125°C operational limits.

Memory IC Part Context

This part belongs to the GD25LQ64 family of SPI NOR flash memories from GigaDevice. The series targets applications needing reliable code storage with varying performance and environmental specifications. Different suffixes indicate variations in package style and operating temperature ranges within the same memory density architecture.

Memory IC Replacement Considerations

Check for GD25LQ64EWAGR or GD25LQ64ESIGR if different packages or slightly lower speeds are acceptable. Verify pin compatibility and voltage levels before substituting.
