GD25Q40CEIGR

Memory IC Overview

The GD25Q40CEIGR is a 4 Mbit NOR flash memory device manufactured by GigaDevice. It features an SPI interface with a maximum clock frequency of 120 MHz and supports Quad I/O operations. The storage organization is 512 k x 8 bits. Operating voltage ranges from 2.7 V to 3.6 V, with a maximum active read current of 20 mA. The component operates within an industrial temperature range of -40°C to +85°C. It is housed in an USON-8 package measuring 3x2x0.45 mm.

Memory IC Feature Summary

• Supports standard SPI and Quad I/O interfaces for flexible data transfer modes.
• Provides non-volatile code storage suitable for embedded applications.
• Operates reliably across the full industrial temperature range.

Memory IC Applications

• Embedded systems requiring compact code storage
• Industrial control equipment firmware storage
• Consumer electronics application programming

Memory IC Procurement Notes

Verify the specific suffix CEIGR against official datasheets to confirm the USON-8 package and industrial temperature grade. Ensure compatibility with system voltage requirements between 2.7 V and 3.6 V. Confirm moisture sensitivity level handling procedures during assembly. Check for RoHS compliance documentation if required by target market regulations.

Memory IC Selection Notes

Select this part when a small USON-8 footprint is required for 4 Mbit capacity. Compare against GD25Q40CSIGR if SOP-8 packaging is preferred instead. Consider GD25Q40EKIGR if higher clock speeds up to 133 MHz are necessary. Verify that the 120 MHz speed meets system timing constraints.

Memory IC Part Context

This component belongs to the GD25Q40C series of SPI NOR flash memories. The series offers various package options including SOP-8 and USON-8. These devices are designed for general-purpose code storage in embedded systems. The manufacturer provides multiple variants differing primarily in package type and operating speed specifications.

Memory IC Replacement Considerations

GD25Q40CSIGR offers identical electrical characteristics but uses an SOP-8 package. GD25Q40EKIGR provides increased speed up to 133 MHz in a USON-8 package. Verify pinout compatibility before substitution as package dimensions differ significantly between USON and SOP formats.
