GD25LQ255EFIRR

Memory IC Overview

The GD25LQ255EFIRR is a 256M-bit (32M x 8) 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 uniform 4K-byte sectors and 32/64K-byte blocks, utilizing SOP-16 packaging in a tape-and-reel configuration.

Memory IC Feature Summary

• Supports Dual I/O data transfer at up to 266Mbits/s and Quad I/O at up to 532Mbits/s
• Includes advanced security features such as 128-bit Unique ID and Serial Flash Discoverable Parameters
• Provides flexible software and hardware write protection mechanisms via WP# pin and status register bits
• Enables Execute In Place (XiP) operation with continuous read wrap functionality

Memory IC Applications

• Code storage for embedded systems requiring high-speed boot operations
• Firmware storage for IoT devices operating within low voltage constraints
• Data logging applications benefiting from uniform sector architecture
• Consumer electronics utilizing compact SOP-16 surface mount packages

Memory IC Procurement Notes

Verify the specific ordering suffix EFIRR corresponds to the SOP-16 package and tape-and-reel shipping format. Confirm that the 1.65V to 2.0V voltage range aligns with your system's power supply design. Ensure compatibility with standard SPI or Quad SPI controllers supporting the required command set.

Memory IC Selection Notes

Select this component when a 256M-bit density is required alongside a low-voltage 1.65V-2.0V supply rail. The SOP-16 package offers a larger footprint compared to WSON options but provides robust mounting. Consider the 133MHz clock speed for applications demanding fast read latencies and efficient code execution.

Memory IC Part Context

This part belongs to the GD25LQ series of Dual and Quad Serial Flash memories. The 'E' suffix indicates the 1.65V-2.0V voltage variant, while 'Q' denotes Quad SPI support. The 'I' specifies industrial temperature range operation, and 'RR' indicates the reel packaging type.

Memory IC Replacement Considerations

GD25LQ255EWIGY: Identical electrical specifications and memory organization but utilizes an 8-WSON package instead of SOP-16.
