GD25R256EWIGR

Memory IC Overview

The GD25R256EWIGR is a 256 Mbit SPI NOR Flash memory IC manufactured by GigaDevice. It features Quad I/O support with a maximum clock frequency of 104 MHz and an access time of 7 ns. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports surface mount installation in an 8-WSON (5x6) package. It functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and Quad I/O interfaces for flexible data transfer modes.
• Provides high-speed read performance with a maximum clock frequency of 104 MHz.
• Ensures reliable operation in industrial environments with extended temperature coverage.

Memory IC Applications

• Code storage in embedded systems requiring fast boot times
• Industrial control applications needing wide temperature stability
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix 'R' against official datasheets to confirm reel packaging requirements. Confirm that the 104 MHz speed grade matches system timing constraints. Ensure the 8-WSON footprint aligns with PCB layout specifications. Check current availability status as supply levels may fluctuate.

Memory IC Selection Notes

Select this component when a balance between moderate speed and low cost is required for 256 Mbit capacity. Compare against the GD25Q256 series if higher 133 MHz speeds are necessary. Verify power supply compatibility with the 2.7 V to 3.6 V operating range before integration into the design.

Memory IC Part Context

This part belongs to the GD25R series, which offers a specific speed bin lower than the GD25Q series but maintains the same density and package form factor. It serves as a cost-effective alternative for designs where maximum clock speed is not the primary constraint.

Memory IC Replacement Considerations

GD25Q256EWIGR is a parameter-equivalent substitute offering higher clock speeds. GD25B256EWIGR is another comparable option within the same package family.
