GD25D20ETIGR

Memory IC Overview

The GD25D20ETIGR is a 2 Mbit Serial NOR Flash memory device manufactured by GigaDevice. It supports Standard SPI and Dual Output interfaces, enabling data transfer speeds up to 160 Mbits/s in dual mode. The device operates on a single power supply voltage ranging from 2.7 V to 3.6 V. It features a uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. Key electrical characteristics include a maximum clock frequency of 104 MHz for fast read operations and a typical standby current of 0.1 μA.

Memory IC Feature Summary

• Supports Standard SPI and Dual Output modes for flexible interface compatibility
• Provides hardware and software write protection mechanisms including block protect bits
• Integrates advanced security features such as OTP locks and unique identification
• Ensures high endurance with minimum 100,000 program/erase cycles

Memory IC Applications

• Code storage for microcontrollers and embedded systems
• Data logging applications requiring reliable non-volatile storage

Memory IC Procurement Notes

Verify the specific package variant (SOP8 or USON8) required for your design, as the base part number covers multiple packages. Confirm that the ordering suffix matches the desired tape and reel quantity. Ensure voltage levels align with the 2.7V to 3.6V operating range. Check for moisture sensitivity handling requirements during assembly.

Memory IC Selection Notes

Select this component when a small footprint and low power consumption are critical. The Dual Output mode offers higher throughput than standard SPI without requiring additional pins. Consider the uniform sector size for easy erasure management. Verify that the 2 Mbit capacity meets your application's code and data storage needs.

Memory IC Part Context

This part belongs to the GD25D series of Serial NOR Flash memories. It shares architectural similarities with the GD25D40E but offers half the density. The series is designed for cost-sensitive applications requiring reliable code execution and data retention. It complements GigaDevice's broader portfolio of SPI NOR and NAND flash solutions.

Memory IC FAQ

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

Standard SPI uses four signals (SCLK, CS#, SI, SO) for data transfer. Dual Output mode utilizes two bidirectional I/O pins (IO0 and IO1) to transfer data at twice the rate, achieving up to 160 Mbits/s.

How is write protection implemented in this device?

Write protection is achieved through software commands setting Block Protect (BP) bits in the Status Register, and/or hardware protection via the WP# pin. The SRP bit determines whether the Status Register itself is protected.
