GD25Q128EYIGY

Memory IC Overview

The GD25Q128EYIGY is a 128 Mbit SPI NOR flash memory manufactured by GigaDevice. It features a storage capacity of 128 Mbit organized as 16 M x 8 bits. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports a maximum clock frequency of 133 MHz. It utilizes an SPI interface with active read current up to 25 mA. The component is housed in an 8-pin WSON package and functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and dual/quad I/O data transfer modes for flexible interface compatibility.
• Includes hardware write protection, absolute write protection, and software-based protection mechanisms.
• Features non-volatile storage technology ensuring data retention without continuous power supply.

Memory IC Applications

• Embedded systems requiring code execution from flash memory
• Consumer electronics storing firmware and configuration data
• Mobile communication devices needing compact non-volatile storage

Memory IC Procurement Notes

Verify the specific suffix 'GY' corresponds to the WSON-8 package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements against your assembly process specifications. Ensure the ordering documentation explicitly references the manufacturer part number GD25Q128EYIGY to avoid confusion with similar SOP or other package variants within the same family.

Memory IC Selection Notes

Select this component when a small form factor is required due to its WSON-8 packaging compared to larger SOP options. Choose this model if the application demands operation within the standard 2.7V to 3.6V voltage range rather than the lower voltage requirements of the L-series variants. Consider the 133 MHz speed capability for applications needing faster read access times.

Memory IC Part Context

This part belongs to the GD25Q128E series of SPI NOR flash memories produced by GigaDevice. The series is designed for high-performance embedded applications. The 'Q' designation indicates support for Quad I/O operations, while the 'E' suffix typically denotes specific feature sets or revisions within the product line. It serves as a non-volatile storage solution for code and data in various electronic devices.

Memory IC Replacement Considerations

GD25Q128ESIGR shares identical electrical specifications but uses an 8-SOP package instead of WSON-8. GD25Q128EWIGR offers the same performance metrics in an 8-WSON package. Verify pinout compatibility and physical footprint differences before substituting these alternatives in existing designs.
