GD25LB128EYIGR

Memory IC Overview

The GD25LB128EYIGR is a 128M-bit (16M-byte) 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, quad SPI, and QPI interfaces with a maximum clock frequency of 133MHz. The device features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware write protection, OTP locks for security registers, and a unique ID.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 532Mbits/s
• Provides software-based write protection via block protect bits and status register lock-down options
• Includes 128-bit unique identification for each device and three sets of security registers with OTP locks
• Features low power consumption with typical standby current of 11μA and deep power-down current of 1μA

Memory IC Applications

• Embedded systems requiring code execution in place (XiP)
• Consumer electronics with limited power supply constraints
• Industrial control applications needing reliable non-volatile storage
• Automotive infotainment and instrument clusters

Memory IC Procurement Notes

Verify the specific package variant matches the design requirements, as the GD25LB128E series is available in multiple packages including WSON-8, USON-8, SOP-8, SOP-16, and TFBGA-24. Confirm that the 1.65V to 2.0V operating voltage range aligns with the system's power rails. Ensure compatibility with the required interface mode, noting that Quad Enable (QE) is permanently set to 1 for this part number.

Memory IC Selection Notes

Select the GD25LB128EYIGR when a low-voltage operation between 1.65V and 2.0V is required. This component is suitable for designs prioritizing high-speed read performance through Quad SPI or QPI modes. Consider the uniform sector architecture for simplified erase operations. Verify that the 8-WSON package dimensions fit the PCB layout constraints.

Memory IC Part Context

The GD25LB128E belongs to GigaDevice's GD25L series of low-voltage SPI NOR flash memories. It is designed for applications requiring high performance and security within a compact footprint.

Memory IC FAQ

Is the Quad Enable (QE) bit configurable?

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

What is the default state of the device after power-up?

Upon power-up, the device defaults to Standard/Dual/Quad SPI mode with all volatile bits reset to their initial states.

How is the status register protected?

The status register can be protected via software commands, power supply lock-down, or one-time programmable settings using SRP1 and SRP0 bits.
