GD9FU1G8F2AMGI

Memory IC Overview

The GD9FU1G8F2AMGI is a 1Gb SLC NAND flash memory IC manufactured by GigaDevice. It features an ONFI 1.0 compatible parallel interface with an x8 data bus organization (128M x 8). The device operates within a supply voltage range of 2.7V to 3.6V and utilizes a 48-TSOP I package measuring 12mm x 20mm. Key electrical parameters include a maximum random read time of 25ns, a typical page program time of 300us, and a typical block erase time of 3ms. It supports industrial operating temperatures from -40°C to +85°C.

• Consumer electronics including digital cameras and MP3 players
• Industrial control systems requiring wide temperature ranges
• Automotive infotainment and telematics units

Memory IC Procurement Notes

Verify the specific ordering suffix 'AMGI' corresponds to the TSOP-I-48 package and industrial temperature grade (-40°C to +85°C) required for your design. Confirm that the host controller supports the ONFI 1.0 protocol and x8 data width. Ensure power supply rails are stable within the 2.7V to 3.6V range during all operational states to prevent data corruption or device damage.

Memory IC Selection Notes

Select this component when a 1Gb capacity with parallel interface is needed for cost-sensitive applications. It is suitable for designs where moderate speed is acceptable but high density in a small footprint is required. Consider the 48-pin TSOP package if board space allows for larger footprints compared to BGA options. Ensure the system can handle the required ECC overhead for long-term data retention.

Memory IC Part Context

This part belongs to the GD9Fx1GxF2A series of SLC NAND flash memories. It shares architectural similarities with other variants in the family, differing primarily in voltage range, package type, and organization. The series is designed for general-purpose storage needs in embedded systems, offering a balance between performance, reliability, and manufacturing cost.

Memory IC Replacement Considerations

GD9FS1G8F2AMGI: Same capacity and interface but operates at 1.7V-1.95V; requires voltage level adjustment.

Memory IC FAQ

What is the minimum number of valid blocks guaranteed?

The datasheet specifies a minimum of 1004 valid blocks out of a total of 1024 blocks.

How does the Cache Read operation improve performance?

Cache Read allows the host to read data from the previous page while simultaneously reading the next page from the array, reducing idle time.
