GD25LQ128EYIGR

Memory IC Overview

The GD25LQ128EYIGR is a 128 Mbit SPI NOR flash memory component manufactured by GigaDevice. It features a 16M x 8 organization and supports Quad I/O SPI interfaces with a maximum clock frequency of 133 MHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and is housed in an 8-WSON package measuring 6x8 mm. It provides access times of 7 ns and supports standard, dual, and quad SPI protocols for efficient data transfer.

Memory IC Feature Summary

• Supports high-speed Quad I/O SPI interface with up to 133 MHz clock frequency
• Operates on a single 2.7 V to 3.6 V power supply
• Provides 128 Mbit non-volatile storage capacity
• Compatible with standard, dual, and quad SPI command sets

Memory IC Applications

• Embedded systems requiring code execution from flash memory
• Consumer electronics firmware storage
• Industrial control system applications
• Mobile device boot code storage

Memory IC Procurement Notes

Verify the specific suffix 'YIGR' against official datasheets to confirm the 8-WSON(6x8) package and 133 MHz speed grade. Ensure the design supports the 2.7 V to 3.6 V operating voltage range. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Check for RoHS compliance status if required by regional regulations.

Memory IC Selection Notes

Select this part when a compact 8-pin surface-mount package is required for 128 Mbit storage. It is suitable for designs needing faster read speeds compared to lower-frequency variants. Consider the 2.7 V minimum voltage requirement; it is not compatible with 1.8 V or 1.65 V only systems. Compare with GD25LQ128EQIGR if a smaller USON package is preferred.

Memory IC Part Context

This component belongs to the GD25Q128E series of SPI NOR flash memories. It shares architectural similarities with other devices in the family but differs in package type and specific electrical characteristics. The YIGR suffix denotes the specific WSON-8 packaging and performance grade offered by GigaDevice for space-constrained applications.

Memory IC Replacement Considerations

GD25B128EWIGR is listed as a substitute option by distributors. Verify functional compatibility and pinout alignment before replacement.
