GD25D20CKIGR

Memory IC Overview

The GD25D20CKIGR is a 2M-bit (256K x 8) Serial NOR Flash memory manufactured by GigaDevice. It operates on a single 2.7V to 3.6V power supply and supports Standard SPI and Dual Output interfaces with a maximum clock frequency of 104MHz under a 30pF load. The device features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks, organized into 256-byte pages. It includes hardware write protection via the WP# pin and software protection through status register bits.

Memory IC Feature Summary

• Supports standard SPI and dual output data transfer modes for flexible interface compatibility.
• Features uniform sector and block architecture allowing granular erase operations.
• Provides hardware write protection via the dedicated WP# pin to secure memory content.
• Integrates a 128-bit unique identifier for individual device authentication.

Memory IC Applications

• Code storage in embedded systems requiring reliable non-volatile memory.
• XIP (Execute In Place) applications utilizing fast read capabilities.
• Industrial control systems operating within specified temperature ranges.
• Consumer electronics devices needing compact surface-mount packaging.

Memory IC Procurement Notes

Verify the specific package variant matches design requirements, as the CK suffix denotes USON8 1.5x1.5mm. Confirm voltage range compatibility with system power rails. Ensure ESD handling procedures are followed during assembly. Check for RoHS compliance documentation if required by regional regulations. Validate pinout alignment with schematic designs before procurement.

Memory IC Selection Notes

Select this component when a 2M-bit capacity is sufficient for application needs. Choose based on the requirement for USON8 1.5x1.5mm packaging for space-constrained designs. Consider the 104MHz clock speed for high-throughput read operations. Evaluate the need for dual output support versus standard SPI only. Assess environmental conditions against the industrial temperature rating.

Memory IC Part Context

This part belongs to the GD25D20C series, which offers 2M-bit density options. It shares architectural similarities with the GD25D40C but provides half the storage capacity. The series is designed for general-purpose code storage and data logging applications. It complements higher-density variants in the GigaDevice portfolio for scalable design implementations.

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 and IO1 pins simultaneously to transfer data at twice the rate.

How is hardware write protection enabled?

Hardware write protection is enabled by driving the WP# pin low, which protects the Block Protect bits and Status Register from modification.
