GD25LQ16LIGR

Memory IC Overview

The GD25LQ16LIGR is a 16M-bit (2M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single 1.65V to 2.1V power supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 104MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware/software write protection and 128-bit unique IDs. The component is housed in an 8-ball WLCSP package.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface modes for flexible data transfer rates.
• Provides software and hardware write protection mechanisms via status register bits and dedicated pins.
• Includes a 128-bit unique identifier for individual device authentication.
• Features uniform sector and block architecture for consistent erase and program operations.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics firmware repositories
• Industrial control system configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the required WLCSP packaging and tape-and-reel delivery format. Confirm that the operating voltage range of 1.65V to 2.1V aligns with the target system's power rails. Ensure compatibility with the 104MHz maximum clock frequency for the intended application speed requirements.

Memory IC Selection Notes

Select this component when a compact form factor is necessary due to the WLCSP package option. It is suitable for applications demanding low power consumption during standby and deep power-down modes. Consider the uniform sector size if the application requires frequent small-scale data updates or boot code storage.

Memory IC Part Context

This part belongs to the GD25LQ16C series of 1.8V uniform sector dual and quad serial flash memories. The series offers various package options including SOP, USON, and WLCSP to accommodate different board space constraints. The GD25LQ16LIGR specifically utilizes the Wafer Level Chip Scale Package variant.

Memory IC FAQ

What is the function of the QE bit in the status register?

The Quad Enable (QE) bit allows the device to operate in Quad SPI mode. When set, it reconfigures the WP# and HOLD# pins to function as IO2 and IO3 data lines.

How does the device handle write protection?

Write protection is managed through software commands setting Block Protect (BP) bits in the status register, or via the hardware WP# pin which can lock the status register settings.
