GD25WQ20ETIGR

Memory IC Overview

The GD25WQ20ETIGR is a 2 Mbit (256 K x 8) NOR flash memory manufactured by GigaDevice. It supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 104 MHz. The device operates on a single power supply ranging from 1.65 V to 3.6 V. It features uniform sector architecture with 4 KB sectors and 32/64 KB blocks. Key electrical characteristics include a typical standby current of 11 μA and deep power-down current of 0.1 μA. The component ensures data retention for 20 years and endurance of at least 100,000 program/erase cycles.

Memory IC Feature Summary

• Supports Dual and Quad SPI modes for high-speed data transfer up to 416 Mbits/s.
• Provides flexible software and hardware write protection mechanisms via status register bits and WP# pin.
• Includes advanced security features such as a 128-bit unique ID and programmable security registers with OTP locks.
• Enables Execute In Place (XiP) operation with continuous read capabilities to reduce instruction fetch latency.

Memory IC Applications

• Firmware storage in embedded systems
• Code execution in place (XiP) applications
• Consumer electronics requiring non-volatile code storage
• Industrial control systems needing reliable data retention

Memory IC Procurement Notes

Verify the specific package variant (SOP-8 or USON-8) required for your design, as the datasheet covers multiple packages. Confirm that the voltage range of 1.65V to 3.6V aligns with your system's power supply rails. Ensure compatibility with standard SPI mode 0 and 3 protocols. Check for moisture sensitivity level requirements during assembly.

Memory IC Selection Notes

Select this component when a 2 Mbit capacity is sufficient for firmware or data storage needs. It is suitable for designs requiring low power consumption due to its microampere standby currents. Consider the SOP-8 or USON-8 package based on board space constraints. Ensure the host controller supports Dual/Quad SPI commands if higher throughput is desired.

Memory IC Part Context

This part belongs to the GD25WQ40E/20E series of uniform sector serial flash memories. It shares architectural similarities with other members like the GD25WQ40E but offers half the density. The 'ETIGR' suffix typically indicates the tape and reel packaging format for surface-mount technology.

Memory IC Replacement Considerations

GD25WQ40ETIGR: Offers double density (4 Mbit) with identical interface and pinout. Compatible for direct replacement if additional storage is acceptable. Verify voltage and speed specifications match application requirements.
