GD25D20EEIGR

Memory IC Overview

The GD25D20EEIGR is a 2M-bit Serial NOR Flash memory manufactured by GigaDevice. It supports Standard SPI and Dual Output interfaces, enabling data transfer speeds up to 160 Mbits/s with a maximum clock frequency of 104 MHz for fast read operations. The device operates on a single power supply voltage ranging from 2.7V to 3.6V. It features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key specifications include a typical standby current of 0.1μA, minimum 100,000 program/erase cycles endurance, and 20-year data retention.

Memory IC Feature Summary

• Supports Standard SPI and Dual Output modes for flexible interface compatibility and high-speed data transfer.
• Provides software and hardware write protection mechanisms via Block Protect bits and the WP# pin.
• Includes advanced security features such as 512-byte Security Registers with One-Time Programmable (OTP) locks.
• Features a unique 128-bit ID for each device to ensure individual identification and traceability.

Memory IC Applications

• Code storage for microcontrollers and embedded systems
• BIOS and firmware storage in consumer electronics
• Data logging and configuration storage in industrial control systems

Memory IC Procurement Notes

Verify the specific package variant, as the EE suffix denotes USON-8 (3x2mm). Confirm voltage range compliance with your system's 2.7V to 3.6V requirement. Check for RoHS compliance status if required by your manufacturing standards. Ensure ESD handling procedures are followed during assembly due to the small form factor.

Memory IC Selection Notes

Select this component when a 2M-bit capacity is required with dual I/O speed benefits. It is suitable for applications needing robust write protection and security registers. Compare against GD25D40E if higher density is needed. Consider the USON-8 package constraints for PCB layout. Verify that the host controller supports the necessary SPI commands for dual output operation.

Memory IC Part Context

This part belongs to the GD25D series of Uniform Sector Serial Flash memories. It shares architectural similarities with the GD25D40E but offers half the density. The series is designed for cost-effective, high-reliability code storage solutions. It complements GigaDevice's broader portfolio of SPI NOR flashes targeting various voltage and performance requirements.

Memory IC FAQ

What is the difference between Standard SPI and Dual Output modes?

Standard SPI uses separate pins for input (SI) and output (SO), while Dual Output mode utilizes both IO0 (SI) and IO1 (SO) simultaneously to transfer data at twice the rate, achieving up to 160 Mbits/s.

How does the hardware write protection work?

Hardware write protection is enabled by driving the WP# pin low. When active, it prevents changes to the Block Protect bits (BP2-BP0) and the Status Register Protect (SRP) bit, locking the configured protected areas.
