GD25D40CKIGR

Memory IC Overview

The GD25D40CKIGR is a 4 Mbit NOR flash memory from GigaDevice, organized as 512K x 8 bits. It operates on a single 3.3V supply within the 2.7V to 3.6V range and supports SPI interfaces with clock frequencies up to 100 MHz. The device utilizes a USON-8 package measuring 1.5x1.5 mm with a thickness of 0.45 mm. It features uniform sector architecture, software/hardware write protection, and an industrial temperature range spanning -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI and Dual Output modes for data transfer
• 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 a unique 128-bit identification number for each device

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control applications needing wide temperature tolerance
• Consumer electronics utilizing compact surface-mount packaging

Memory IC Procurement Notes

Verify the specific suffix 'KIGR' corresponds to the USON-8 1.5x1.5mm package and tape-and-reel delivery format. Confirm that the industrial grade (-40°C to +85°C) aligns with environmental requirements. Ensure compatibility with 3.3V logic levels and SPI command sets before integration.

Memory IC Selection Notes

Select this component when a small form factor is required alongside standard SPI interface compatibility. The USON-8 package offers space efficiency compared to SOP or TSSOP variants. Consider the dual-output capability if higher read speeds are necessary without increasing clock frequency.

Memory IC Part Context

This part belongs to the GD25D40C series, which includes various package options such as SOP-8, TSSOP-8, and different USON sizes. The 'K' indicates the USON-8 1.5x1.5mm package, while 'I' denotes the industrial temperature range. The 'GR' suffix typically signifies tape-and-reel packaging for automated assembly.
