The component supports Dual/Quad SPI and standard SPI interfaces with a maximum clock frequency of 104 MHz. It is housed in a 16-pin SOP package designed for surface mount technology. The device functions reliably across an industrial temperature range from -40°C to +85°C, with a maximum active read current of 20 mA.

Memory IC Feature Summary

• Supports Dual and Quad SPI communication modes alongside standard SPI interface
• Operates on a wide voltage supply range from 1.65 V to 3.6 V
• Includes hardware reset functionality for system reliability

Memory IC Applications

• Industrial control systems requiring robust data storage
• Consumer electronics utilizing low-voltage power supplies
• IoT devices needing non-volatile code execution capability

Memory IC Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure the SOP-16 footprint aligns with your PCB layout constraints. Check for any recent product change notices that might affect long-term availability or specifications.

Memory IC Selection Notes

Select this component when a wide operating voltage range including 1.8V and 3.3V is required. It is suitable for applications needing Dual/Quad SPI support at moderate speeds up to 104 MHz. Consider this part for designs where SOP-16 packaging is preferred over smaller footprints. Verify thermal performance within the specified -40°C to +85°C range for your environment.

Memory IC Part Context

This part belongs to the GD25W series of SPI NOR flash memories from GigaDevice. The series is characterized by its wide voltage operation capabilities. It shares architectural similarities with other GD25 variants but distinguishes itself through specific voltage tolerances and interface support configurations defined in its technical documentation.

Memory IC Replacement Considerations

GD25LB256EFIRR offers similar capacity and packaging but operates at a lower voltage range (1.65V-2V). GD25Q256EFIRR provides Quad SPI support but requires a higher minimum voltage (2.7V). Verify interface compatibility and voltage levels before substitution.
