GD25WD10CKIGR

Memory IC Overview

The GD25WD10CKIGR is a 1M-bit (128K x 8) SPI NOR flash memory manufactured by GigaDevice. It operates within a voltage range of 1.65V to 3.6V and supports standard SPI and Dual Output interfaces with clock frequencies up to 100MHz at higher voltages. The device features uniform sector architecture, advanced security including a unique ID, and industrial temperature ratings from -40°C to +85°C. Packaged in USON-8 (1.5x1.5mm), it offers low power consumption and high endurance.

Memory IC Feature Summary

• Supports Standard SPI and Dual Output data transfer modes for flexible interface compatibility.
• Features software and hardware write protection mechanisms via WP# pin and status register bits.
• Includes a 128-bit Unique ID for individual device identification and security.
• Provides long-term data retention and high program/erase cycle endurance.

Memory IC Applications

• Industrial control systems requiring wide voltage operation
• IoT sensor modules with space constraints
• Wearable electronic devices
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific package variant matches design requirements, as the series includes multiple footprint options. Confirm the suffix indicates the correct tape-and-reel packaging configuration. Ensure the industrial temperature grade aligns with environmental operating conditions. Cross-reference the manufacturer part number with official datasheets to validate electrical characteristics before integration.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small-capacity non-volatile storage. The USON-8 package suits designs with strict PCB area limitations. Choose based on the need for dual-output speed improvements over standard SPI without increasing pin count. Verify voltage compatibility across the full 1.65V to 3.6V range for varying system power rails.

Memory IC Part Context

This part belongs to the GD25WDxxC series of uniform sector serial flash memories. It shares architectural similarities with other members like the GD25WD05C but offers double the density. The series is designed for applications needing reliable code execution and data storage in portable and industrial environments.

Memory IC FAQ

What is the maximum clock frequency for fast read operations?

The device supports a maximum clock frequency of 100MHz for fast read operations when powered between 3.0V and 3.6V.

How does the hardware write protection function?

Hardware protection is enabled by driving the WP# pin low while the SRP bit in the status register is set, locking the block protect bits against modification.
