GD25Q16CTEGR

Memory IC Overview

The GD25Q16CTEGR is a 16M-bit (2M x 8) NOR flash memory IC manufactured by GigaDevice. It operates on a single 2.7V to 3.6V power supply and features an SPI interface with standard, dual, and quad modes. The device supports a maximum clock frequency of 120 MHz for fast read operations. It utilizes a uniform sector architecture consisting of 4K-byte sectors and 32/64K-byte blocks. The component is housed in an 8-lead SOP package (150mil) and is rated for industrial temperature ranges from -40°C to +125°C.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI interfaces for flexible data transfer rates up to 480 Mbits/s.
• Features software and hardware write protection mechanisms including block protect bits and WP# pin control.
• Includes advanced security features such as a 128-bit unique ID and four 256-byte security registers with OTP locks.
• Allows Execute In Place (XIP) operation with continuous read capabilities and wrap modes.

Memory IC Applications

• Code storage for microcontrollers and system booting
• Parameter storage in embedded systems
• Firmware storage for IoT devices

Memory IC Procurement Notes

Verify the specific ordering suffix 'TEGR' corresponds to the SOP8 150mil package and industrial temperature range (-40°C to +125°C). Confirm that the reel packaging matches your automated assembly requirements. Ensure compatibility with the 2.7V to 3.6V voltage domain of your target application circuit.

Memory IC Selection Notes

Select this part for applications requiring uniform sector erase architecture and high-speed quad I/O access. It is suitable for designs needing robust data protection via hardware WP# pins or software block protection. Consider the 150mil SOP package constraints for PCB layout and thermal management within the specified industrial temperature range.

Memory IC Part Context

This component belongs to the GD25Q16C series of 3.3V uniform sector dual and quad serial flash memories. It shares architectural similarities with other members of the GD25Q family but is distinguished by its specific package type and temperature rating. The series is designed for general-purpose non-volatile storage needs in consumer and industrial electronics.

Memory IC FAQ

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

When the QE bit is set to 1, the WP# and HOLD# pins are disabled as dedicated control inputs and function as bidirectional data I/O pins (IO2 and IO3) for Quad SPI operations.

What is the purpose of the Hold# signal?

The Hold# signal pauses serial communication without resetting internal logic. It requires CS# to remain low and SCLK to be low when the signal goes low. It does not stop ongoing program or erase cycles.
