GD25LD40EKIGR

Memory IC Overview

The GD25LD40EKIGR is a 4 Mbit Serial NOR Flash memory device manufactured by GigaDevice. It supports standard SPI and Dual Output interfaces with a maximum clock frequency of 50 MHz for fast read operations. The device operates on a single power supply voltage ranging from 1.65 V to 2.0 V. It features a uniform sector architecture with 512K x 8 organization, housed in an 8-USON package measuring 1.5x1.5 mm. The component is designed for industrial temperature ranges spanning from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and Dual Output data transfer modes
• Features uniform sector and block architecture for flexible memory management
• Includes hardware and software write protection mechanisms via WP# pin and status register bits
• Provides advanced security features including unique ID and OTP security registers

Memory IC Applications

• Code storage for microcontrollers and system-on-chip devices
• Data logging applications requiring non-volatile retention
• Embedded systems with low voltage power constraints
• Industrial control units operating in wide temperature environments

Memory IC Procurement Notes

Verify the specific suffix 'EKIGR' against the manufacturer's official ordering guide to confirm package type and tape/reel specifications. Ensure the design accommodates the 1.65V to 2.0V supply range and USON-8 footprint. Confirm compliance with RoHS directives as stated in the datasheet before finalizing procurement.

Memory IC Selection Notes

Select this component when a small form factor is required alongside low power consumption. The 1.8V nominal operation makes it suitable for battery-powered or energy-efficient designs. Consider the Dual Output capability if higher throughput is needed without increasing clock speed. Verify that the host controller supports the required SPI command set for page programming and sector erasing.

Memory IC Part Context

This part belongs to the GD25LD series of Uniform Sector Standard and Dual Serial Flash memories. It shares architectural similarities with the GD25LE and GD25Q series but is distinguished by its lower voltage operation range. The series targets applications demanding high reliability and compact packaging solutions for embedded storage needs.
