GD25WQ64ESIGR

Memory IC Overview

The GD25WQ64ESIGR is a non-volatile NOR flash memory integrated circuit manufactured by GigaDevice. It features a storage capacity of 64 Mbit organized as 8M x 8 bits. The device supports SPI and Quad I/O interfaces with a maximum clock frequency of 104 MHz and an access time of 12 ns. It operates within a supply voltage range of 1.65V to 3.6V and functions across a temperature range of -40°C to +85°C. The component is housed in an 8-SOP surface-mount package.

Memory IC Feature Summary

• Supports standard SPI, Dual SPI, and Quad SPI data transmission modes for flexible interface compatibility.
• Enables Execute-In-Place (XiP) execution directly from the flash memory to reduce system latency.
• Provides hardware and software write protection mechanisms including top/bottom block protection via WP# pin.

Memory IC Applications

• Code storage for microcontrollers and system-on-chip (SoC) architectures
• Firmware and application code execution in consumer electronics devices
• Data logging and configuration storage in industrial control systems

Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the 8-SOP package and commercial temperature grade during procurement. Confirm RoHS3 compliance status if required by regional regulations. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications to avoid partial reel handling issues.

Memory IC Selection Notes

Select this component when a wide voltage range of 1.65V to 3.6V is required compared to fixed 3V parts. Choose over the GD25Q64E series if lower power consumption at reduced clock speeds is prioritized over higher performance. Verify that the 8-SOP package fits the PCB footprint constraints and thermal requirements of the target design.

Memory IC Part Context

This part belongs to the GD25WQ64E series, which is designed for low-power applications compared to the standard GD25Q series. It shares the same 64 Mbit density but offers optimized power characteristics suitable for battery-operated devices. The series maintains compatibility with standard SPI protocols while providing enhanced endurance and data retention specifications.

Memory IC Replacement Considerations

GD25Q64ESIGR: Higher speed variant (133 MHz) but requires 2.7V minimum voltage. GD25LQ64ESIGR: Lower voltage support down to 1.65V but limited to 2.0V maximum. GD25WQ64ENIGR: Same electrical specs but in 8-USON package.
