GD25Q16CSJGR

Memory IC Overview

The GD25Q16CSJGR is a 16M-bit NOR flash memory device manufactured by GigaDevice. It features a 2M x 8 organization and operates on a single 3.3V power supply within a 2.7V to 3.6V range. The component supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 120 MHz. It utilizes an SOP-8 (208mil) package and is rated for industrial operating temperatures from -40°C to +105°C.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI communication protocols for flexible data transfer rates.
• Features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks.
• Includes hardware and software write protection mechanisms via the WP# pin and status register bits.
• Provides advanced security features including unique identification and programmable security registers.

Memory IC Applications

• Firmware storage in embedded systems
• Code execution in place (XIP) applications
• Industrial control system data logging
• Consumer electronics configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'SJGR' against the manufacturer's current ordering guide to confirm package dimensions and tape/reel specifications. Ensure compatibility with the required industrial temperature range (-40°C to +105°C) for your application environment. Confirm RoHS compliance status through official documentation before integration.

Memory IC Selection Notes

Select this component when a 16M-bit capacity with industrial temperature ratings is required. The SOP-8 (208mil) package suits designs needing surface-mount assembly with specific footprint constraints. Consider the 120 MHz speed limit for high-throughput read operations compared to higher-speed variants in the family.

Memory IC Part Context

This part 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. The GD25Q16CSJGR specifically denotes the SOP-8 (208mil) variant optimized for industrial temperature ranges.

Memory IC Replacement Considerations

GD25Q16CSIGR: Similar SOP-8 package but rated for commercial temperature range (-40°C to +85°C).

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), enabling Quad SPI operations.

What is the purpose of the Hold# signal?

The Hold# signal pauses serial communications without interrupting ongoing program or erase operations, allowing the device to be temporarily suspended.
