GD25LB16EWIGR

Memory IC Overview

The GD25LB16EWIGR is a 16 Mbit Serial NOR Flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2.0 V and supports SPI, Dual SPI, Quad SPI, and QPI interfaces with a maximum clock frequency of 133 MHz. The device features a uniform sector architecture comprising 2M bytes organized into 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware write protection, OTP locks, and a unique ID.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532 Mbits/s.
• Includes software and hardware write protection mechanisms with top/bottom block protection capabilities.
• Features 128-bit unique identification and three 3x1024-byte security registers with one-time programmable lock bits.

Memory IC Applications

• Execute in Place (XiP) code storage for system-on-chip applications
• BIOS and firmware storage in embedded systems
• Data logging and configuration storage in industrial controllers

Memory IC Procurement Notes

Verify the specific suffix 'WIGR' against the manufacturer's official ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with the 1.65V-2.0V operating voltage range required by the target application circuitry. Confirm that the WSON-8 package dimensions align with the PCB footprint design constraints.

Memory IC Selection Notes

Select this component when low-voltage operation between 1.65V and 2.0V is required. It is suitable for designs needing high-speed read access via Quad I/O or QPI modes. Consider its uniform sector structure for simplified erase management compared to mixed sector devices. Verify that the 133 MHz clock speed meets the system's timing requirements.

Memory IC Part Context

This part belongs to the GD25LB16E series of Dual and Quad Serial Flash memories from GigaDevice. The series is designed for applications requiring high performance and low power consumption. It shares architectural similarities with other GD25LQ and GD25Q variants but differs in voltage specifications and interface defaults.

Memory IC FAQ

Is the Quad Enable (QE) bit changeable?

No, the QE bit is permanently set to 1 by default and cannot be changed, enabling Quad I/O operations continuously.

What is the typical standby current consumption?

The typical standby current is 10 μA.
