GD25LQ40CTIGR

Memory IC Overview

The GD25LQ40CTIGR is a non-volatile NOR flash memory integrated circuit manufactured by GigaDevice. It features a storage capacity of 4 Mbit organized as 512K x 8 bits. The device utilizes an SPI Quad I/O interface with a maximum clock frequency of 104 MHz. It operates within a supply voltage range of 1.65 V to 2.1 V and supports an industrial temperature range from -40°C to +85°C. The component is housed in an 8-SOP surface-mount package.

Memory IC Feature Summary

• Supports standard SPI and Quad I/O modes for flexible data transfer
• Industrial temperature rating suitable for demanding environments
• Low voltage operation optimized for power efficiency

Memory IC Applications

• Firmware storage in embedded systems
• Code execution in microcontroller applications
• Data logging in industrial devices

Memory IC Procurement Notes

Verify the specific suffix 'C' and 'TIGR' against the manufacturer's current datasheet to confirm pinout, packaging dimensions, and RoHS compliance status. Ensure the design accounts for the 1.65V to 2.1V operating voltage window and the 8-SOP package thermal characteristics during integration.

Memory IC Selection Notes

Select this component when a 4 Mbit density is required with low voltage compatibility. The Quad I/O interface offers higher throughput compared to standard SPI variants. Verify that the system power supply aligns with the 1.65V minimum requirement and that the SOP-8 footprint matches the PCB layout constraints.

Memory IC Part Context

This part belongs to the GD25LQ series of SPI NOR flash memories designed for low-voltage applications. It shares the same interface protocol and package style as other members in the family but differs in storage density and specific electrical parameters such as read current and write cycle times defined in the official specification.
