GD25R512MEFIRR

Memory IC Overview

The GD25R512MEFIRR is a 512 Mbit SPI NOR Flash memory IC manufactured by GigaDevice Semiconductor (HK) Limited. It features Quad I/O and Double Data Rate (DTR) interface capabilities with a maximum clock frequency of 200 MHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports an industrial temperature range from -40°C to +85°C. Organized as 64 M x 8 bits, it is housed in a 16-SOP package.

Memory IC Feature Summary

• Supports high-speed Quad I/O and DTR data transfer modes for enhanced throughput
• Designed for reliable non-volatile code storage applications
• Operates within standard industrial temperature specifications

Memory IC Applications

• Firmware storage
• Boot code retention
• Configuration data archiving

Memory IC Procurement Notes

Verify the specific suffix 'R' against official datasheets to confirm Quad I/O/DTR functionality, as other variants like 'E' or 'T' may differ in interface speed. Ensure the 16-SOP package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.

Memory IC Selection Notes

Select this component when high-speed sequential read performance is required via DTR mode. Compare against standard SPI variants if lower power consumption at reduced speeds is acceptable. Verify that the 2.7V minimum operating voltage aligns with your system's power rail stability under all load conditions.

Memory IC Part Context

This part belongs to the GD25 series of SPI NOR Flash memories from GigaDevice. The series offers densities ranging from 512Kb to 2Gb. While some family members are AEC-Q100 qualified for automotive use, specific qualification status for this exact model number must be verified in its dedicated datasheet rather than assuming general family certification.

Memory IC Replacement Considerations

GD25B512MEFIRR: Standard SPI interface, 166 MHz max clock. GD25T512MEFIRR: Standard SPI interface, 166 MHz max clock. Note that these substitutes lack the Quad I/O/DTR 200 MHz capability of the GD25R variant.
