GD25Q16CTJG

Memory IC Overview

The GD25Q16CTJG 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 4K-byte sectors and 32/64K-byte blocks. The component is housed in an SOP-8 package with a 150mil width and is rated for industrial temperatures ranging from -40°C to +105°C.

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 including block protect bits and WP# pin control.
• Includes advanced security features such as a unique ID and programmable security registers with OTP locks.
• Features execute-in-place capability allowing direct code execution from the memory.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips
• BIOS and firmware storage in embedded systems
• Data logging and configuration parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'TJG' corresponds to the SOP-8 150mil package and industrial temperature grade (-40°C to +105°C). Confirm that the tube packaging matches production requirements. Ensure compatibility with the host controller's SPI mode and voltage levels before integration.

Memory IC Selection Notes

Select this part when a 16M-bit density is required with uniform sector architecture. It is suitable for applications needing high-speed read access via Quad SPI. Consider the SOP-8 150mil package constraints and industrial temperature range during board layout and thermal design.

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 high reliability with 100,000 program/erase cycles and 20-year data retention. It is designed for cost-effective and space-constrained embedded applications requiring non-volatile code storage.

Memory IC Replacement Considerations

GD25Q16CSJG: Same electrical specifications but uses SOP-8 208mil package.

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 function as dedicated data I/O pins (IO2 and IO3) to support Quad SPI operations.

What is the purpose of the CMP bit in the status register?

The CMP bit provides flexibility for array protection by changing the interpretation of the Block Protect (BP) bits, allowing different top or bottom block protection schemes.
