GD25B512MEFIRR

Memory IC Overview

The GD25B512MEFIRR is a 512M-bit (64M-byte) NOR flash memory manufactured by GigaDevice. It features a uniform sector architecture with 4K-byte sectors and 32K/64K-byte blocks, organized as 64M x 8 bits. The device supports Standard SPI, Quad SPI, QPI, and DTR modes via a 16-pin SOP package. Operating voltage ranges from 2.7V to 3.6V. Maximum clock frequency reaches 166MHz in standard mode and 133MHz in Quad/DTR modes. Active read current is typically 45mA.

Memory IC Feature Summary

• Supports multiple interface modes including Standard SPI, Quad SPI, QPI, and DTR for high-speed data transfer.
• Provides advanced security features such as hardware write protection via WP# pin and individual block locking capabilities.
• Includes a dedicated hardware reset function accessible through the RESET# pin regardless of operational state.
• Features flexible address modes allowing operation in either 3-byte or 4-byte addressing configurations.

Memory IC Applications

• Execute In Place (XIP) operations for code storage
• Data logging and firmware storage systems
• Industrial control applications requiring robust data retention

Memory IC Procurement Notes

Verify the specific suffix 'EFIRR' against the manufacturer's official ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements within the 2.7V to 3.6V range. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Memory IC Selection Notes

Select this component when a 512M-bit capacity with uniform sector organization is required. It is suitable for designs needing high-speed read performance via Quad or DTR interfaces. Consider the 16-pin SOP package for space-constrained PCB layouts compared to BGA options.

Memory IC Part Context

This part belongs to the GD25B512ME series, which includes various package options such as WSON8 and TFBGA-24. The 'E' indicates the specific package variant, while 'FIRR' denotes the reel packaging configuration. Other variants in the family share identical electrical characteristics but differ in physical footprint.

Memory IC FAQ

How does the device handle hardware write protection?

Hardware write protection is managed via the WP# pin. When WP# is low, it protects the Block Protect bits and Status Register Protection bits from being modified.

What is the default address mode upon power-up?

Upon power-up, the device defaults to 3-byte address mode. The Address Status (ADS) bit in the status register indicates the current mode.
