GD25Q32CWIGR

Memory IC Overview

The GD25Q32CWIGR is a 32M-bit (4M x 8) NOR flash memory IC manufactured by GigaDevice. It operates on a single 2.7V to 3.6V power supply and supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 120 MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It is housed in an 8-lead WSON package measuring 6x5mm and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface operations for flexible data transfer rates.
• Features software and hardware write protection mechanisms including block protect bits and WP# pin control.
• Includes advanced security capabilities such as a unique ID and programmable security registers with OTP locks.

Memory IC Applications

• Firmware storage for embedded systems
• Code execution in place (XIP) applications
• Data logging and configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'WIGR' confirms the WSON-8 (6x5mm) package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure design compatibility with the 2.7V to 3.6V voltage range and 120 MHz clock speed requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 32M-bit capacity is required in a compact surface-mount WSON-8 footprint. It is suitable for designs needing industrial temperature stability and support for high-speed Quad I/O read commands. Verify that the host controller supports the necessary SPI modes and command sets for page programming and sector erasing.

Memory IC Part Context

This part belongs to the GD25Q32C series of 3.3V uniform sector serial flash memories. The 'WIGR' designation specifically identifies the WSON-8 (6x5mm) package variant with tape and reel packaging. Other variants in the series include SOP, USON, and TFBGA packages with different thermal or electrical characteristics.

Memory IC FAQ

What is the difference between the HOLD# and WP# pins?

The HOLD# pin pauses serial communication without resetting internal logic, while the WP# pin provides hardware-based write protection for the status register and memory array depending on the SRP bit settings.

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set to 1, the WP# and HOLD# pins function as bidirectional data I/O pins (IO2 and IO3) to enable Quad SPI operations. When QE is 0, they retain their dedicated control functions.
