GD25LQ40EEIGR

Memory IC Overview

The GD25LQ40EEIGR is a 4M-bit (512K x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V and supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 133MHz. The device features uniform sector architecture with 4KB sectors and 32/64KB blocks. It includes advanced security features such as a 128-bit unique ID, software/hardware write protection, and three 512-byte security registers with OTP locks. The component is housed in an 8-USON package measuring 3x2mm.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 532Mbits/s
• Includes hardware and software write protection mechanisms with block protect bits
• Features a 128-bit unique identifier and three 512-byte security registers with one-time programmable locks
• Enables execute-in-place operation with continuous read wrap functionality

Memory IC Applications

• Code storage for microcontrollers requiring low-voltage operation
• Embedded systems utilizing execute-in-place capabilities
• IoT devices needing compact surface-mount packaging
• Consumer electronics with strict power consumption constraints

Memory IC Procurement Notes

Verify the specific ordering suffix EEIGR corresponds to the USON8 3x2mm package and industrial temperature range. Confirm that the Quad Enable bit configuration aligns with your system's pin usage, as enabling it repurposes WP# and HOLD# pins. Ensure voltage levels match the 1.65V-2.0V specification strictly.

Memory IC Selection Notes

Select this part when a 4M-bit density is required within a small 8-USON footprint. It is suitable for designs constrained by low voltage supplies between 1.65V and 2.0V. Consider its high-speed quad I/O capabilities if bandwidth is critical for code execution. Verify compatibility with existing SPI controllers supporting dual and quad modes.

Memory IC Part Context

This component belongs to the GD25LQ series of serial flash memories designed for low-power applications. It shares architectural similarities with other GD25LQ variants but is distinct in its 4M-bit capacity and specific 1.65V-2.0V voltage range. The series emphasizes reliability and security features for embedded storage needs.

Memory IC Replacement Considerations

GD25LQ40ETIGR: Identical electrical specifications and memory organization, differing only in the SOP8 package format instead of USON8.
