GD25Q64EWIGR

Memory IC Overview

The GD25Q64EWIGR is a 64M-bit (8M-byte) uniform sector serial flash memory from GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 133MHz for fast read operations. The device features a 256-byte page buffer, allowing typical page program times of 0.5ms. Erase operations include sector (4KB), block (32KB/64KB), and chip erase, with typical times of 45ms, 0.15s/0.25s, and 25s respectively. It operates on a single 2.7V to 3.6V supply, offering low power consumption with 12μA standby current. The memory architecture consists of 128 blocks of 64KB or 256 blocks of 32KB, each containing 16 sectors of 4KB.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad Serial Peripheral Interface (SPI) modes for flexible data transfer rates.
• Features uniform sector and block architecture enabling consistent erase and protection granularity across the memory array.
• Includes advanced security mechanisms such as hardware/software write protection, one-time programmable lock bits, and a unique 128-bit ID.
• Enables Execute In Place (XiP) operation with continuous read capabilities to reduce instruction fetch latency.

Memory IC Applications

• Code storage in embedded systems requiring direct execution from flash.
• Data logging applications needing reliable non-volatile storage with high endurance.
• Firmware storage for microcontrollers and system-on-chip devices.
• Configuration parameter storage in industrial control equipment.

Memory IC Procurement Notes

Verify the specific package suffix 'IGR' against the manufacturer's ordering guide to confirm pinout and physical dimensions. Ensure compatibility with the target board's footprint, particularly for SOP8 or USON packages. Confirm voltage requirements match the 2.7V-3.6V range. Check for any special handling instructions related to electrostatic discharge during assembly.

Memory IC Selection Notes

Select this component when a 64M-bit capacity with uniform sector protection is required. It is suitable for designs needing high-speed Quad I/O access and robust data retention. Consider the available package options like SOP8 or WSON8 based on space constraints. Ensure the host controller supports the necessary SPI commands and dummy cycle configurations for optimal performance at higher frequencies.

Memory IC Part Context

The GD25Q64E series is part of GigaDevice's uniform sector serial flash family. This line emphasizes flexibility through multiple SPI modes and comprehensive protection features. The GD25Q64EWIGR variant specifically denotes a particular package and temperature grade within this broader portfolio, sharing core electrical and command set characteristics with other members of the GD25Q64E series.

Memory IC Replacement Considerations

Check for cross-reference parts with identical 64M-bit density, uniform sector architecture, and compatible SPI command sets. Verify that alternative components support the same voltage range and package type if mechanical fit is critical. Ensure substitute parts offer comparable endurance and data retention specifications.

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 bidirectional I/O pins (IO2 and IO3) to support Quad SPI operations. When QE is 0, these pins retain their dedicated Write Protect and Hold functions.

What is the purpose of the Dummy Configuration (DC) bit?

The DC bit configures the number of dummy cycles inserted between address transmission and data output. This adjustment is necessary to maintain signal integrity and correct timing at higher clock frequencies, such as 133MHz.
