GD25Q64CSIG

Memory IC Overview

The GD25Q64CSIG is a 64M-bit (8M x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates within a voltage range of 2.7V to 3.6V and supports clock frequencies up to 120MHz. The device utilizes an 8-lead SOP package with 208mil width. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks, supporting standard, dual, and quad SPI interfaces for data transfer rates up to 480Mbits/s.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI communication modes for flexible data throughput.
• Includes hardware and software write protection mechanisms via WP# pin and status register bits.
• Features a unique 128-bit ID for individual device identification.
• Provides advanced security capabilities including three 3KB security registers with one-time programmable locks.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics firmware applications
• Mobile communication devices

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product selection guide to confirm package type and temperature grade. Confirm RoHS compliance status and check for any discontinuation notices or recommended new designations prior to finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 64M-bit capacity with industrial temperature range and SOP8 packaging is required. Ensure the host system supports the necessary SPI modes and voltage levels. Verify that the application does not require the hardware reset pin, which is available only on special order.

Memory IC Part Context

This part belongs to the GD25Q64C series of 3.3V uniform sector serial flash memories. It is designed for high-performance applications requiring reliable data retention and fast program/erase speeds. The series supports execute-in-place (XIP) operations for direct code execution from the memory.
