GD25WD40CKIGR

Memory IC Overview

The GD25WD40CKIGR is a 4 Mbit Serial NOR Flash memory manufactured by GigaDevice. It features a 1.65 V to 3.6 V single power supply voltage range and supports Standard SPI and Dual Output interfaces with clock frequencies up to 100 MHz. The device utilizes a USON-8 package (1.5x1.5 mm) and operates within an industrial temperature range of -40°C to +85°C. Memory organization consists of 512 K x 8 bits, with uniform sectors of 4 K bytes and blocks of 32/64 K bytes.

Memory IC Feature Summary

• Supports standard SPI and Dual Output data transfer modes for flexible interface compatibility.
• Provides hardware and software write protection mechanisms via the WP# pin and status register bits.
• Includes a 128-bit unique identifier for individual device authentication.

Memory IC Applications

• Industrial control systems requiring wide voltage operation
• Consumer electronics firmware storage
• IoT devices needing low power standby characteristics

Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the USON-8 package and tape-and-reel delivery format as defined in the manufacturer's ordering guide. Confirm that the industrial temperature grade (-40°C to +85°C) matches the application environment requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity is required with a compact USON-8 footprint. Ensure the system design accommodates the 1.65 V minimum supply voltage if operating at lower power levels. Verify that the host controller supports the necessary SPI command set for page programming and sector erasing operations.
