GD25B512MEYIGR

Memory IC Overview

The GD25B512MEYIGR is a 512M-bit (64M x 8) NOR flash memory manufactured by GigaDevice. It operates within a voltage range of 2.7V to 3.6V and supports standard SPI, Quad SPI, QPI, and DTR modes with a maximum clock frequency of 166 MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes hardware write protection via the WP# pin, software block protection, and a dedicated RESET# pin. The component is housed in an 8-lead WSON package.

Memory IC Feature Summary

• Supports high-speed data transfer through Quad I/O and Double Transfer Rate (DTR) modes alongside standard SPI interfaces.
• Provides flexible data protection mechanisms including hardware write protection, individual block locking, and global sector protection.
• Features a uniform sector architecture allowing for efficient erase and program operations across the memory array.
• Includes advanced security features such as a unique ID and one-time programmable lock bits for security registers.

Memory IC Applications

• Code storage for embedded systems requiring execute-in-place (XIP) capabilities
• Firmware storage in consumer electronics devices
• Data logging applications in industrial control systems

Memory IC Procurement Notes

Verify the specific ordering suffix 'YIGR' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required voltage levels and interface modes for your target application design.

Memory IC Selection Notes

Select this component when a high-density 512M-bit NOR flash with uniform sector architecture is required. Consider the WSON-8 package size constraints and the need for high-speed Quad/DTR read operations. Verify that the system supports the necessary SPI command set for configuration and operation.

Memory IC FAQ

What is the default address mode upon power-up?

The device defaults to 3-Byte address mode upon power-up, indicated by the Address Status (ADS) bit being 0.

How is the status register protected from unintended writes?

The status register can be protected via software settings, hardware protection using the WP# pin, power supply lock-down, or one-time programmable lock bits.
