GD25WB256EYIGR

Memory IC Overview

The GD25WB256EYIGR is a 256 Mbit NOR flash memory component manufactured by GigaDevice. It utilizes an 8-WSON package with dimensions of 6x8 mm and supports surface-mount installation. The device operates within a supply voltage range of 1.65 V to 3.6 V and features Dual/Quad SPI interface capabilities with a maximum clock frequency of 104 MHz. It is designed for industrial applications, functioning reliably between -40°C and +85°C. The memory organization is specified as 32 M x 8 bits.

Memory IC Feature Summary

• Supports standard SPI as well as Dual and Quad SPI modes for flexible data transfer options.
• Operates with a wide supply voltage range starting from 1.65 V up to 3.6 V.
• Includes hardware write protection, absolute write protection, and software write protection mechanisms.

Memory IC Applications

• Industrial control systems requiring robust memory solutions
• Consumer electronics devices needing low-voltage operation
• Embedded systems utilizing code execution from flash memory

Memory IC Procurement Notes

Verify the specific package variant (WSON-8) and voltage specifications against the official datasheet before integration. Confirm that the design supports the required Dual/Quad SPI interface modes. Ensure thermal management aligns with the industrial temperature range of -40°C to +85°C. Check for any recent product change notices regarding manufacturing updates or pinout modifications.

Memory IC Selection Notes

Select this component when a wide voltage range including 1.65 V is required, distinguishing it from standard 3.3V-only parts. Consider the 104 MHz clock speed and Dual/Quad SPI support for performance needs. Evaluate the 8-WSON(6x8) footprint against available PCB space. Compare against other GD25 series parts if higher clock speeds or different temperature ranges are needed.

Memory IC Part Context

This part belongs to the GD25WB series of NOR flash memories from GigaDevice. It shares the 256 Mbit capacity and WSON-8 packaging common across many variants in the family. Key differentiators include the extended low-voltage support down to 1.65 V and the specific industrial temperature rating. It serves as a non-volatile storage solution for code and data retention.
