GD9FS2G8F3AMGI

Memory IC Overview

The GD9FS2G8F3AMGI is a 2 Gbit Single Level Cell (SLC) Parallel NAND Flash memory manufactured by GigaDevice. It features an 8-bit I/O interface with a memory organization of 128M x 8. The device utilizes a page size of 2K bytes plus 64 bytes of spare capacity and supports multi-plane operations across two planes. It operates within a supply voltage range of 1.7 V to 1.95 V and is rated for industrial temperatures from -40°C to +85°C. The component is housed in a 63-ball FBGA package.

Memory IC Feature Summary

• Supports ONFI 1.0 compatible parallel interface with multiplexed address, command, and data buses.
• Enables high throughput through cache read functionality allowing simultaneous array reading and cache output.
• Provides extended reliability with 100K program/erase cycles when utilizing Error Correcting Code (ECC).
• Includes hardware write protection via the WP# pin to prevent unintended program or erase operations.

Memory IC Applications

• Embedded code storage for mobile devices and smartphones.
• Data logging and firmware storage in consumer electronics.
• Industrial control systems requiring reliable non-volatile memory.
• IoT devices needing compact footprint and low power consumption.

Memory IC Procurement Notes

Verify the specific ordering suffix 'AMGI' against the manufacturer's official datasheet to confirm the exact package type and temperature grade. Ensure the design accommodates the 1.7V to 1.95V VCC supply requirement. Confirm that the host controller supports the required parallel interface timing and command set defined in the GD9Fx2GxF3A specification before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2 Gbit density with an 8-bit parallel interface is required. It is suitable for designs constrained by the 63-FBGA package dimensions. Consider the 1.8V operating voltage range if power efficiency is critical compared to 3.3V alternatives. Ensure the application can handle the necessary ECC overhead for the specified 100K cycle endurance.

Memory IC Part Context

This part belongs to the GD9FS2G8F3A series, which includes variants with different voltages and packages. The 'S' designation indicates the 1.8V core voltage, distinguishing it from the 3.3V 'U' series. The '2G' denotes the 2 Gbit capacity, while '8' specifies the 8-bit bus width. This series is designed for cost-effective, high-density storage solutions in portable and embedded applications.

Memory IC Replacement Considerations

GD9FS2G8F3ALGI: Same electrical specifications but may differ in package or tray configuration.

Memory IC FAQ

How does the Cache Read function improve performance?

Cache Read allows the host to read data from the cache register while the device simultaneously reads the next page from the flash array, reducing idle time between sequential accesses.

What is the role of the WP# pin?

The WP# pin provides hardware write protection. When driven low, it disables all program and erase operations to protect the data in the flash array.
