GD25F256FW2GY

Memory IC Overview

The GD25F256FW2GY is a 256 Mbit SPI NOR Flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 2.7 V to 3.6 V and supports Single, Dual, Quad, and DTR I/O bus interfaces. The component achieves clock frequencies up to 200 MHz in standard modes and 104 MHz in DTR mode. It utilizes an 8-WSON package with dimensions of 5x6 mm and functions across an industrial temperature range of -40°C to 105°C.

Memory IC Feature Summary

• Supports multiple interface modes including Single, Dual, Quad, and Double Data Rate (DTR) for flexible data throughput.
• Integrates hardware-based Error Correction Code (ECC) algorithms and CRC checksums for data integrity.
• Includes security registers with One-Time Programmable (OTP) locks for code protection.
• Features a hardware reset pin for reliable system initialization.

Memory IC Applications

• Consumer electronics firmware storage
• Industrial control system code execution
• Internet of Things (IoT) device memory
• PC and peripheral embedded storage

Memory IC Procurement Notes

Verify the specific package dimension suffix 'W' corresponds to the required 5x6 mm footprint against schematic constraints. Confirm that the operating voltage range of 2.7V to 3.6V aligns with the target system power rails. Ensure the industrial temperature grade (-40°C to 105°C) meets environmental specifications. Check current availability status as supply may be restricted due to market conditions.

Memory IC Selection Notes

Select this component when a 256 Mbit density is required with support for high-speed Quad and DTR SPI interfaces. It is suitable for designs needing hardware ECC and OTP security features without external logic. Compare against the FY2GR variant if a 6x8 mm package is preferred instead of the 5x6 mm form factor. Ensure the controller supports the necessary I/O modes for optimal performance.

Memory IC Part Context

This part belongs to the GD25F series of SPI NOR Flash memories from GigaDevice. The series covers densities from 512Kb to 2Gb and supports various voltage levels including 3V and 1.8V variants. The GD25F family is designed for general-purpose non-volatile storage with a focus on reliability and small package options for embedded applications.

Memory IC Replacement Considerations

GD25F256FY2GR offers identical electrical specifications but uses an 8-WSON(6x8) package instead of the 5x6 mm footprint. Verify mechanical compatibility before substitution.
