GD25LF255ESIGR

Memory IC Overview

The GD25LF255ESIGR is a 256 Mbit SPI NOR flash memory manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2 V and supports a maximum clock frequency of 166 MHz. The device utilizes an 8-bit data bus width and features an SPI interface. It is housed in an SOP-8 package designed for surface mount installation. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface communication with frequencies up to 166 MHz
• Provides non-volatile code storage with low voltage operation capabilities
• Includes hardware reset functionality and security registers with OTP locks

Memory IC Applications

• Consumer electronics firmware storage
• Industrial control system code execution
• IoT device embedded memory

Memory IC Procurement Notes

Verify the specific suffix 'GR' against the manufacturer datasheet to confirm reel packaging specifications. Ensure the design accommodates the 1.65 V to 2 V operating voltage window. Confirm SOP-8 footprint compatibility during schematic capture. Validate that the application environment remains within the specified -40°C to +85°C temperature limits for reliable operation.

Memory IC Selection Notes

Select this component when a 256 Mbit density is required with a narrow 1.65 V to 2 V power supply constraint. The SOP-8 package offers a standard surface-mount solution for space-constrained designs. Consider the 166 MHz speed capability if high-throughput code execution is necessary. Verify that the target system does not require automotive-grade certification, as this specific part number lacks AEC-Q100 qualification documentation.

Memory IC Part Context

This part belongs to the GD25LF series of SPI NOR flash memories from GigaDevice. The series targets applications requiring reliable code storage with low power consumption. While the broader family includes automotive-grade variants qualified to AEC-Q100, this specific model focuses on general-purpose industrial and consumer markets. It shares interface similarities with other devices in the lineup but differs in capacity and voltage specifications.
