GD25LD20CKIGR

Memory IC Overview

The GD25LD20CKIGR is a 2 Mbit NOR flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2 V and utilizes an SPI interface with a maximum clock frequency of 50 MHz. The memory organization is specified as 256K x 8 bits. This component is housed in an USON-8 surface-mount package and supports industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and Dual I/O interfaces for data communication
• Designed for low-voltage operation suitable for portable applications
• Industrial temperature rating ensures reliability across wide thermal ranges

Memory IC Applications

• Portable consumer electronics requiring low power consumption
• Embedded systems utilizing serial flash storage
• Industrial control devices operating in varied environmental conditions

Memory IC Procurement Notes

Verify the specific suffix 'CKI' against official manufacturer documentation to confirm package type, tape-and-reel configuration, and regional compliance status. Ensure the target system provides the required 1.65 V to 2 V supply rail, as this part differs significantly from 3.3 V variants. Confirm availability through authorized distributors given potential supply chain fluctuations.

Memory IC Selection Notes

Select this component when a 2 Mbit capacity is required with a strict 2 V supply constraint. The USON-8 package offers a compact footprint compared to SOP or TSSOP options. Consider the 50 MHz speed limit if higher throughput is needed, as other series may offer faster clock rates. Verify that the dual I/O support meets the bandwidth requirements of the host controller.

Memory IC Part Context

This part belongs to the GD25LD20C series, which focuses on low-voltage performance. Unlike the GD25D or GD25Q series that typically operate at 3.3 V, this series is optimized for 1.8 V domains. The 'L' designation generally indicates this lower voltage capability within the manufacturer's portfolio.
