GD25LD40CTIGR

Memory IC Overview

The GD25LD40CTIGR is a non-volatile NOR flash memory integrated circuit manufactured by GigaDevice. It provides a storage capacity of 4 Mbit, organized as 512K x 8 bits. The device utilizes a Serial Peripheral Interface (SPI) with Dual I/O support for data transfer. It operates within a supply voltage range of 1.65 V to 2 V and supports maximum clock frequencies up to 50 MHz. The component is designed for surface mount installation in an 8-SOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and Dual I/O serial communication protocols for flexible interface compatibility.
• Features uniform sector architecture suitable for code execution and data storage applications.
• Operates at low voltage levels to optimize power consumption in portable electronic devices.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile data retention
• Consumer electronics utilizing low-power embedded memory solutions
• Firmware storage for microcontroller-based embedded applications

Memory IC Procurement Notes

Verify the specific suffix 'C' indicates the commercial/industrial grade variant and 'I' denotes the SOP-8 package configuration against the manufacturer's official datasheet. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the assembly process to ensure adherence to environmental standards.

Memory IC Selection Notes

Select this component when dual-speed SPI interface capabilities are required alongside low-voltage operation constraints. Ensure the design accommodates the 8-SOP footprint and validates thermal performance within the specified -40°C to +85°C operating range. Compare against single-speed variants if higher throughput is not critical for the target application.

Memory IC Part Context

This part belongs to the GD25LQ/LD series of NOR flash memories from GigaDevice. It shares architectural similarities with other members like the GD25LQ40CTIGR but differs in interface speed and voltage specifications. The series is widely used in embedded systems where cost-effective, reliable storage for boot code and configuration data is essential.

Memory IC Replacement Considerations

GD25LQ40CTIGR offers similar capacity but supports Quad I/O and higher speeds. GD25LD40COIGR provides the same electrical characteristics in a TSSOP-8 package. Verify pinout compatibility and voltage tolerances before substituting.
