GD25Q64CZIGY

Memory IC Overview

The GD25Q64CZIGY 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 standard, dual, and quad SPI interfaces with a maximum clock frequency of 120MHz. The device utilizes a TFBGA-24 package (6x4mm ball array) and is rated for industrial temperatures from -40°C to +85°C. Key electrical parameters include a typical deep power-down current of 1μA and support for execute-in-place (XIP) operations.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 480Mbits/s in Quad I/O mode.
• Features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks for efficient erasure.
• Includes advanced security mechanisms such as hardware/software write protection, top/bottom block protection, and three 3KB security registers with OTP locks.
• Provides a unique 128-bit ID per device and supports Serial Flash Discoverable Parameters (SFDP).

Memory IC Applications

• Storing firmware and boot code for microcontrollers via Execute In Place (XIP).
• Data storage in IoT devices and consumer electronics requiring high reliability.
• Industrial control systems operating within extended temperature ranges.

Memory IC Procurement Notes

Verify the specific suffix 'ZY' against the manufacturer's official ordering guide to confirm the TFBGA-24 package and industrial temperature grade. Confirm RoHS compliance status through the latest datasheet revision. Check for any special order requirements regarding hardware reset pins or OTP features not standard in this configuration.

Memory IC Selection Notes

Select this component when a compact TFBGA-24 footprint is required for 64M-bit storage. Ensure the design supports 2.7V to 3.6V supply rails. Verify that the host controller can drive the necessary SPI modes (Standard/Dual/Quad) and handle the 120MHz clock speed if high throughput is needed.
