GD25LQ128ESJGR

Memory IC Overview

The GD25LQ128ESJGR is a 128 Mbit NOR flash memory device manufactured by GigaDevice. It utilizes an SPI interface with support for dual and quad I/O operations, achieving a maximum clock frequency of 166 MHz. The component operates within a supply voltage range of 1.65 V to 2 V and features an 8-pin SOP package. It supports surface mount installation and functions reliably across a wide industrial temperature range from -40°C to +105°C.

Memory IC Feature Summary

• Supports uniform sector architecture for flexible data organization
• Enables high-speed data transfer via dual and quad SPI modes
• Operates at low voltage levels suitable for power-constrained systems

Memory IC Applications

• Industrial control systems requiring wide temperature tolerance
• Embedded firmware storage in consumer electronics
• IoT devices utilizing low-power SPI interfaces

Memory IC Procurement Notes

Verify the specific suffix 'J' against official datasheets to confirm the extended temperature rating (-40°C to +105°C). Ensure compatibility with 1.65V to 2V supply rails. Confirm package dimensions match SOP-8 specifications before integration into PCB layouts.

Memory IC Selection Notes

Select this part when high-speed read access up to 166 MHz is required alongside broad thermal stability. Compare against the GD25LQ128ESIGR variant if a narrower commercial temperature range (-40°C to +85°C) suffices for the application environment.

Memory IC Part Context

This component belongs to the GD25LQ128E series of uniform sector serial flash memories. It shares architectural similarities with other members like the GD25LQ128EWIGR but differs in package type and thermal specifications. The series targets applications needing reliable non-volatile storage with fast read capabilities.
