GD25LQ128EYJGR

Memory IC Overview

The GD25LQ128EYJGR is a 128 Mbit NOR flash memory device manufactured by GigaDevice. It utilizes an SPI interface with a maximum clock frequency of 166 MHz. The component operates within a supply voltage range of 1.65 V to 2 V and supports surface mount installation in a WSON-8 package. It functions reliably across an industrial temperature range from -40°C to +105°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface communication for efficient data transfer.
• Provides non-volatile storage capability for persistent data retention without power.
• Designed for compact surface-mount applications utilizing a small outline package.

Memory IC Applications

• Embedded systems requiring code execution from flash memory
• Industrial control units operating in wide temperature environments
• Consumer electronics devices needing compact storage solutions

Memory IC Procurement Notes

Verify the specific suffix YJGR against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target system's voltage levels, as this part requires a 1.65 V to 2 V supply. Confirm that the design accommodates the WSON-8 footprint and thermal requirements for operation up to 105°C.

Memory IC Selection Notes

Select this component when a low-voltage 128 Mbit NOR flash is required for space-constrained designs. The 166 MHz clock speed offers performance advantages over standard 120 MHz variants. Verify that the application environment stays within the specified -40°C to +105°C range to ensure long-term reliability and compliance with industrial standards.

Memory IC Part Context

This part belongs to the GD25LQ128E series of uniform sector SPI NOR flash memories. It shares architectural similarities with other members like GD25LQ128EWIGR but differs in package type and operational temperature limits. The YJGR suffix specifically denotes the WSON-8 packaging variant optimized for high-density board layouts.

Memory IC Replacement Considerations

GD25LQ128EWIGR offers similar electrical characteristics but operates up to 85°C and uses a different package. GD25LB128EYJGR provides comparable storage but requires a higher 2.7 V to 3.6 V supply voltage. Verify pinout compatibility before substituting these alternatives.
