GD25LQ32DWIGR

Memory IC Overview

The GD25LQ32DWIGR is a 32M-bit (4M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V. The device supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 120MHz. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. The component is housed in an 8-WSON package measuring 6x5mm and is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports Dual and Quad I/O data transfer modes alongside standard SPI for high-speed read operations.
• Includes advanced security features such as hardware/software write protection and one-time programmable lock bits.
• Features flexible erase and program architectures allowing suspend and resume capabilities during operations.

Memory IC Applications

• Embedded systems requiring code storage
• Consumer electronics firmware
• Industrial control applications

Memory IC Procurement Notes

Verify the specific suffix 'WIGR' corresponds to the WSON-8 6x5mm package and tape-and-reel delivery format. Confirm the voltage range matches the 1.65V to 2.0V specification for low-power designs. Ensure the industrial temperature grade (-40°C to +85°C) aligns with environmental requirements. Check current availability status as manufacturing changes may occur.

Memory IC Selection Notes

Select this part when a 32M-bit capacity is required with a 1.8V nominal supply voltage. It is suitable for designs needing quad SPI interface speeds up to 120MHz. Consider the WSON-8 footprint constraints and industrial temperature rating. Compare against other GD25LQ32 variants if different packages or voltage ranges are needed.

Memory IC Part Context

This component belongs to the GD25LQ32D series of 1.8V Uniform Sector Dual and Quad Serial Flash memories. The series offers various package options including SOP, USON, and WLCSP. The 'GD25LQ32DWIGR' specifically denotes the WSON-8 variant with industrial temperature grading and reel packaging.

Memory IC FAQ

What is the default mode of operation upon power-up?

Upon power-up, the device defaults to Standard/Dual/Quad SPI mode. QPI mode must be explicitly enabled using the Enable QPI command.

How is the Quad Enable bit managed?

The Quad Enable (QE) bit is a non-volatile bit in the Status Register. It must be set to 1 to enable Quad SPI operations, which repurposes the WP# and HOLD# pins as IO2 and IO3.
