GD25LQ128ESIGR

Memory IC Overview

The GD25LQ128ESIGR is a 128 Mbit SPI NOR flash memory component manufactured by GigaDevice. It features a storage organization of 16 M x 8 and supports a maximum clock frequency of 120 MHz with an access time of 7 ns. The device operates within a supply voltage range of 1.65 V to 2 V and has a maximum active read current of 20 mA. It utilizes an 8-SOP surface-mount package and is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports Dual and Quad I/O Serial Peripheral Interface (SPI) modes for flexible data transfer speeds.
• Features uniform sector architecture suitable for code execution and data storage applications.
• Designed for low-voltage operation compatible with 1.8V systems.

Memory IC Applications

• Embedded system firmware storage
• Consumer electronics code execution
• Industrial control application storage

Memory IC Procurement Notes

Verify the specific suffix 'IGR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering documentation matches the 8-SOP package dimensions and pinout configuration required by the target PCB design.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity with 120 MHz performance in an 8-pin SOP package is required. Compare against the GD25Q128 series if higher clock speeds or different voltage ranges are needed, as the Q-series may offer 133 MHz operation. Confirm that the 1.65V to 2V supply requirement aligns with the system power rails.

Memory IC Part Context

This part belongs to the GD25LQ128E family of SPI NOR flash memories. It shares the core 128 Mbit density and 120 MHz speed characteristics with other variants in the series, differing primarily in package type and environmental rating. The ESIGR designation specifically identifies the 8-SOP industrial grade variant.

Memory IC Replacement Considerations

The GD25LQ128DSIG is a pin-compatible alternative within the same family but uses a tube package instead of reel/cut-tape. Verify package compatibility before substitution.
