• Features uniform sector architecture allowing granular erase operations at 4 KByte sector or 32/64 KByte block levels.
• Provides comprehensive data protection via software block protect bits and hardware WP# pin locking.
• Includes advanced security features such as a 128-bit unique device ID and three 3x1024-byte security registers with OTP locks.

Memory IC Applications

• Storing firmware code and bootloaders in embedded systems requiring XIP operation.
• Data storage for IoT devices and consumer electronics.
• Industrial control applications needing reliable non-volatile memory.
• Automotive electronic modules requiring high endurance and retention.

Memory IC Procurement Notes

Verify the specific suffix 'YIGR' against the manufacturer's official ordering guide to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required operating voltage range of 2.7V to 3.6V. Confirm that the design supports the necessary SPI interface signals including CS#, SCLK, SI, SO, WP#, and HOLD#. Check for any specific moisture sensitivity level requirements during assembly.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with uniform sector organization is required. It is suitable for designs needing high-speed read access via Quad SPI mode. Consider the USON package size if board space is limited. Ensure the application can support the 133 MHz clock speed for optimal performance. Verify that the power supply remains stable above the VWI threshold to prevent unintended resets.

Memory IC Part Context

The GD25Q64E belongs to the GD25Q64E series of Serial Flash memories from GigaDevice. This series is designed for high-performance applications requiring fast program/erase speeds and low power consumption. The E variant typically denotes specific electrical characteristics and package options within the broader GD25Q64 family, which includes various pin-compatible packages like SOP8 and WSON8.

Memory IC FAQ

What is the function of the QE bit in the Status Register?

The QE (Quad Enable) bit allows the device to operate in Quad SPI mode. When set to 1, the WP# and HOLD# pins function as bidirectional I/O pins (IO2 and IO3). If QE is 0, these pins retain their dedicated functions.

How does the Hold function work?

The Hold function pauses serial communication without resetting internal logic. It requires CS# to remain low and activates on the falling edge of the HOLD# signal while SCLK is low. Communication resumes when HOLD# goes high while SCLK is low.

What are the available erase sizes for this device?

The device supports Sector Erase (4 KByte), 32 KByte Block Erase, 64 KByte Block Erase, and Chip Erase. The architecture uses uniform sectors, meaning all sectors are the same size.
