GD25Q16CWIGR

Memory IC Overview

The GD25Q16CWIGR is a 16M-bit (2M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single 3.3V power supply with a voltage range of 2.7V to 3.6V. 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-lead WSON package measuring 6x5mm and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI communication protocols 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 128-bit ID and programmable security registers.
• Provides execute-in-place (XIP) operation with continuous read modes.

Memory IC Applications

• Firmware storage for microcontrollers and embedded systems
• Code execution directly from memory (XIP)
• Data logging and configuration storage
• BIOS or boot code storage

Memory IC Procurement Notes

Verify the specific suffix 'WIGR' confirms the WSON-8 6x5mm package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official documentation. Check for end-of-life or not-recommended-for-new-designations prior to finalizing procurement plans.

Memory IC Selection Notes

Select this part when a compact surface-mount solution is required for 16M-bit non-volatile storage. Ensure the design accommodates the WSON-8 footprint and thermal requirements. Verify that the host controller supports the necessary SPI modes, including Quad I/O if high-speed performance is needed.

Memory IC Part Context

This component belongs to the GD25Q16C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. The series offers various package options including SOP, USON, and TFBGA to suit different board space constraints while maintaining consistent electrical characteristics and command sets across the family.

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 to 1, pins WP# and HOLD# function as bidirectional I/O pins IO2 and IO3.

How does the Hold function work?

The Hold# signal pauses serial communications without stopping ongoing program or erase operations. It requires CS# to remain low and starts on the falling edge of Hold# when SCLK is low.
