GD25WQ16EEIGR

Memory IC Overview

The GD25WQ16EEIGR is a 16 Mbit (2M x 8) SPI NOR flash memory manufactured by GigaDevice. It operates within a voltage range of 1.65 V to 3.6 V and supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 104 MHz. The device features uniform sector and block architecture, enabling flexible data protection and erase operations. It includes advanced security features such as a unique ID and OTP security registers. The component is housed in an USON-8 package and is designed for applications requiring high-speed read performance and low power consumption.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates
• Includes software and hardware write protection mechanisms via status register bits
• Features a 128-bit unique identifier for device authentication
• Provides execute-in-place (XiP) capability with continuous read wrap functionality

Memory IC Applications

• Code storage for microcontrollers and system-on-chip devices
• Firmware storage in consumer electronics and IoT devices
• Data logging and configuration storage in industrial equipment
• Boot code storage for embedded systems requiring fast access

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the Quad Enable (QE) bit configuration aligns with the host controller's pin usage, as setting QE disables the dedicated Hold and Write Protect functions. Ensure compatibility with the system's voltage levels and interface timing requirements before integration.

Memory IC Selection Notes

Select this part when a 16 Mbit capacity is required with support for high-speed quad I/O operations. It is suitable for designs needing flexible block protection schemes and secure boot capabilities. Consider the USON-8 package size constraints and the operating temperature range of -40°C to +85°C during board layout and thermal management planning.

Memory IC Part Context

This component belongs to the GD25WQ16E series of uniform sector serial flash memories. The series is characterized by its support for dual and quad SPI protocols, offering higher throughput compared to standard SPI devices. The family emphasizes reliability with high endurance ratings and long data retention periods, making it appropriate for demanding embedded applications.

Memory IC Replacement Considerations

Check for GD25WQ16E variants with different package options if physical footprint changes are acceptable. Verify electrical compatibility with other densities in the GD25WQ series, noting that command sets may vary slightly between generations.
