GD25WQ128EWIGY

Memory IC Overview

The GD25WQ128EWIGY is a 128 Mbit (16M x 8) NOR flash memory in an 8-lead WSON package. It operates on a single voltage supply ranging from 1.65 V to 3.6 V with a maximum active read current of 25 mA. The device supports SPI, Dual SPI, and Quad SPI interfaces at clock frequencies up to 104 MHz. It features uniform 4 KByte sectors and 32/64 KByte blocks, with page programming capabilities of 256 bytes.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface modes for flexible data transfer rates.
• Includes hardware and software write protection mechanisms with top/bottom block selectability.
• Features advanced security options including a unique 128-bit ID and programmable security registers.
• Enables execute-in-place operation with continuous read wrap functionality to reduce latency.

Memory IC Applications

• Firmware storage for microcontrollers and system-on-chip devices
• Code execution directly from memory in embedded systems
• Data logging and configuration storage in industrial equipment

Memory IC Procurement Notes

Verify the specific suffix 'IGY' corresponds to the WSON-8 package variant when ordering. Confirm that the required operating voltage range aligns with the 1.65 V to 3.6 V specification. Ensure design compatibility with the 104 MHz maximum clock frequency for fast read operations. Check for any special order requirements regarding reset pin configurations if using alternative packages.

Memory IC Selection Notes

Select this component for applications requiring low-voltage operation down to 1.65 V. Consider the WSON-8 package for space-constrained surface-mount designs. Evaluate the need for Quad SPI support to maximize data throughput. Verify that the 100,000 program/erase cycle endurance meets the target application's longevity requirements.

Memory IC Part Context

This part belongs to the GD25WQ128E series of dual and quad serial flash memories manufactured by GigaDevice. It shares architectural similarities with other members like the GD25B128E but differs in voltage specifications and performance characteristics. The series is designed for high-reliability non-volatile storage in consumer and industrial electronics.

Memory IC Replacement Considerations

GD25Q128EWIGR is listed as a manufacturer recommended substitute.
