GD25WQ80ETJGR

Memory IC Overview

The GD25WQ80ETJGR is an 8M-bit Serial NOR Flash memory device manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 104 MHz. The device operates on a single power supply voltage ranging from 1.65V to 3.6V. It features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. The memory organization consists of 1M x 8 bits, organized into pages of 256 bytes. It includes advanced security features such as hardware/software write protection and OTP locks.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 416 Mbits/s in Quad I/O mode.
• Provides comprehensive data protection via software block protect bits, hardware WP# pin control, and one-time programmable security register locks.
• Features a uniform sector architecture allowing efficient erase operations across 4K-byte sectors and 32/64K-byte blocks.
• Includes a 128-bit unique ID for each device and supports Serial Flash Discoverable Parameters (SFDP) for system configuration.

Memory IC Applications

• Code storage for microcontrollers and processors requiring execute-in-place (XiP) capabilities.
• Data logging and parameter storage in industrial control systems.
• Firmware storage in consumer electronics and IoT devices.
• Configuration data retention in automotive infotainment and body control modules.

Memory IC Procurement Notes

Verify the specific suffix 'JGR' against the manufacturer's official ordering information table to confirm package type and tape/reel specifications. Ensure compatibility with the required operating voltage range of 1.65V to 3.6V. Confirm that the design accounts for the moisture sensitivity level and reflow soldering profile specified in the datasheet. Check for any regional export control classifications or RoHS compliance documentation requirements prior to final procurement.

Memory IC Selection Notes

Select this component when a high-speed, low-voltage serial flash memory with robust security features is required. The 8M-bit density is suitable for moderate code size applications. Consider the SOP-8 or USON-8 package options based on board space constraints. Ensure the host controller supports the necessary SPI modes, including Quad I/O if maximum read speeds are needed. Verify that the power supply rails can maintain stability within the 1.65V to 3.6V range during all operational states.

Memory IC Part Context

The GD25WQ80E series belongs to GigaDevice's family of uniform sector serial flash memories designed for general-purpose non-volatile storage. It complements other densities in the GD25Q and GD25L series by offering a balance of speed, voltage flexibility, and security. The 'E' variant typically denotes enhanced features or specific process nodes compared to earlier generations. This part is engineered for reliability in diverse environments, supporting both industrial and commercial temperature ranges.

Memory IC Replacement Considerations

Direct replacements include other GD25WQ80 variants with different package suffixes (e.g., ETIGR for SOP-8). Cross-referencing with GD25Q80 or GD25L80 may be possible if voltage levels and interface compatibility align, but verify pinout and command set differences. Always consult the latest datasheet revision to ensure functional equivalence regarding dummy cycles and status register configurations.
