GD25B512MEBJRY

Memory IC Overview

The GD25B512MEBJRY is a 512M-bit (64M-byte) SPI NOR flash memory manufactured by GigaDevice. It supports Standard SPI, Quad SPI, QPI, and DTR Quad I/O interfaces with clock frequencies up to 133 MHz. The device features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It operates on a single power supply voltage ranging from 2.7V to 3.6V. Key specifications include a typical standby current of 16μA, minimum 100,000 program/erase cycles, and 20-year data retention. The component is available in SOP16, WSON8, and TFBGA-24 packages.

Memory IC Feature Summary

• Supports high-speed data transfer via Standard SPI, Quad SPI, QPI, and DTR modes, enabling efficient code execution and fast read operations.
• Includes advanced security features such as hardware/software write protection, individual block locking, and 128-bit unique ID for device authentication.
• Offers flexible memory organization with uniform sector and block erase capabilities, supporting suspend and resume functions during programming or erasing.
• Provides robust reliability with high endurance ratings and long-term data retention suitable for demanding embedded applications.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring execute-in-place (XIP) functionality
• Embedded systems needing reliable non-volatile memory for firmware and configuration data
• Industrial control devices requiring high endurance and wide operating temperature ranges

Memory IC Procurement Notes

Verify the specific package variant (SOP16, WSON8, or TFBGA-24) matches your PCB footprint requirements. Confirm that the voltage supply range of 2.7V to 3.6V aligns with your system design. Ensure compatibility with standard SPI controllers supporting Quad and DTR modes if high-speed performance is required. Check for any regional distribution restrictions or lead time variations before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a high-density 512M-bit capacity is needed with flexible interface options including DTR for maximum throughput. Consider the TFBGA-24 package for compact designs requiring surface-mount technology. Evaluate the need for hardware write protection and security registers if data integrity is critical. Compare against lower density models if space or cost constraints allow for reduced storage capacity.

Memory IC Part Context

The GD25B512ME belongs to GigaDevice's GD25B series of SPI NOR flash memories. This series is designed for applications requiring high performance and reliability. The device complements other densities in the portfolio, offering a balance between storage capacity and speed. It utilizes advanced process technology to ensure low power consumption and high endurance.

Memory IC Replacement Considerations

Direct replacements must match the 512M-bit density, 2.7V-3.6V voltage range, and TFBGA-24 package. Verify pin compatibility and command set adherence for seamless integration. Alternative packages like SOP16 or WSON8 may require board redesign. Consult manufacturer documentation for qualified substitute part numbers within the same product family.
