GD25LB512MEFIRR

Memory IC Overview

The GD25LB512MEFIRR is a 512M-bit (64M-byte) uniform sector 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 SPI, Quad SPI, DTR, and QPI interfaces with a maximum clock frequency of 166MHz. The device features a 64M x 8 organization, 256-byte page programming capability, and hardware write protection via the WP# pin. It is housed in a 16-lead SOP package (300mil) and is designed for industrial temperature ranges.

Memory IC Feature Summary

• Supports high-speed data transfer through Standard SPI, Quad SPI, DTR Quad I/O, and QPI modes.
• Includes advanced security features such as individual block protection, global block/sector lock, and OTP locks for security registers.
• Features a dedicated hardware reset function via the RESET# pin to restore the device to standby mode.
• Provides flexible architecture with 4K-byte sectors and 32/64K-byte blocks for efficient erase operations.

Memory IC Applications

• Execute in Place (XIP) applications requiring high-speed instruction fetch.
• Industrial control systems operating within specified voltage and temperature limits.
• Embedded storage for firmware and code execution in low-voltage environments.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel specifications. Confirm that the system power supply strictly adheres to the 1.65V to 2.0V range to ensure reliable operation. Check for compatibility with the intended interface modes, particularly if utilizing DTR or QPI protocols. Ensure the design accounts for the specific pinout of the SOP-16 package.

Memory IC Selection Notes

Select this component when a low-voltage (1.65V-2.0V) SPI NOR flash is required for 512M-bit capacity. It is suitable for designs needing high read speeds up to 166MHz and support for multiple interface modes including DTR and QPI. Consider the SOP-16 package constraints and industrial temperature range requirements during selection.

Memory IC Part Context

This part belongs to the GD25LB512ME family, which offers uniform sector architecture. The 'FIRR' suffix typically denotes the SOP-16 package with reel packaging. This series is designed for applications demanding high performance and security in low-power environments, distinguishing it from higher voltage variants like the GD25B or GD25T series.

Memory IC FAQ

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

Upon power-up, the device defaults to Standard/Quad SPI mode.

How is the hardware reset function implemented?

The RESET# pin allows the device to be reset by driving it low for a minimum period, returning the flash to standby mode and resetting volatile bits.
