The component supports DTR, Quad SPI, QPI, and standard SPI interfaces with a maximum clock frequency of 166 MHz. It utilizes an 8-WSON (6x8) surface-mount package and maintains synchronous timing. The device is rated for an extended industrial temperature range from -40°C to +125°C, with a maximum active read current of 28 mA.

Memory IC Feature Summary

• Supports Dual Data Rate (DTR) interface for high-speed data transfer alongside standard SPI and QPI modes.
• Operates at low voltage levels between 1.65 V and 2 V to optimize power consumption.
• Provides extended thermal stability suitable for demanding industrial environments up to 125°C.

Memory IC Applications

• Industrial control systems requiring robust temperature performance
• Embedded storage in consumer electronics operating on low voltage supplies
• Firmware storage for microcontrollers utilizing high-speed DTR interfaces

Memory IC Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and electrical characteristics. Confirm that the target application environment remains within the specified -40°C to +125°C operational limits. Ensure the system power supply strictly adheres to the 1.65 V to 2 V range to prevent device malfunction or damage during operation.

Memory IC Selection Notes

Select this component when designs require low-voltage operation combined with high-speed DTR capabilities. It is suitable for applications needing extended temperature ranges where standard commercial-grade parts may fail. Compare against the GD25B series if higher voltage tolerance is required instead of low-power efficiency.

Memory IC Part Context

This part belongs to the GD25LB family of NOR flash memories designed for low-voltage applications. It complements the broader GD25 series by offering enhanced speed through DTR support while maintaining compact packaging. The device serves as a non-volatile storage solution for code execution and data retention in space-constrained electronic designs.

Memory IC Replacement Considerations
