GD9FS1G8F2DMGI

Memory IC Overview

The GD9FS1G8F2DMGI is a 1Gbit Parallel NAND Flash memory manufactured by GigaDevice. It utilizes Single Level Cell (SLC) technology and features an x8 data bus interface. The device operates within a supply voltage range of 1.7V to 1.95V. It is housed in a TSOP(I)-48 package with dimensions of 12mm x 20mm. The memory organization consists of 1024 blocks, each containing 64 pages of 2K + 128 bytes. Key electrical parameters include a typical page program time of 300us and a block erase time of 3ms.

Memory IC Feature Summary

• Supports ONFI 1.0 standard for parallel interface compatibility
• Includes unique identification and one-time programmable area for security
• Features cache read operations for improved sequential access performance
• Provides hardware write protection via dedicated control pins

Memory IC Applications

• Embedded code storage systems
• Industrial automation controllers
• Consumer electronics firmware
• IoT device data logging

Memory IC Procurement Notes

Verify the specific ordering suffix DMGI confirms the TSOP-48 package and 1.8V voltage range. Ensure the design accounts for the required 1.7V to 1.95V power supply tolerance. Confirm that the host controller supports the ONFI 1.0 command set and timing requirements for reliable operation.

Memory IC Selection Notes

Select this component when a 1Gbit density with an x8 parallel interface is required. It is suitable for designs needing SLC reliability and industrial temperature ranges. Consider alternative packages like FBGA if board space constraints differ from the TSOP-48 footprint. Verify voltage compatibility with the system's 1.8V logic levels.

Memory IC Part Context

This part belongs to the GD9Fx1G8F2D series, which includes variants with different voltage ranges and packages. The 'S' in the model indicates the 1.8V operating voltage, distinguishing it from the 'U' variant designed for 3.3V applications. All members share the same core array architecture and command set specifications.

Memory IC Replacement Considerations

GD9FS1G8F2DLGI: Same electrical specs but uses FBGA-63 package. GD9FS1G8F2DDGI: Same electrical specs but uses FBGA-48 package. GD9FU1G8F2DMGI: Identical package and function but requires 2.7V to 3.6V supply voltage.
