W25Q128JWCIQ

Memory IC Overview

The W25Q128JWCIQ is a 128M-bit (16M-byte) Serial Flash memory component manufactured by Winbond Electronics. It operates on a single 1.7V to 1.95V power supply and supports standard, Dual, and Quad SPI interfaces with clock frequencies up to 133MHz. The device features uniform 4KB sectors and 64KB blocks for flexible erasure. It is housed in a 24-ball TFBGA package measuring 8x6mm and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-performance Dual and Quad SPI operations including XIP capabilities
• Includes advanced security features such as hardware write protection and individual block locks
• Features low power consumption with active current of 1mA and power-down current below 1µA
• Provides flexible architecture with uniform sector erase and suspend/resume functionality

Memory IC Applications

• Code shadowing to RAM
• Direct code execution via Dual/Quad SPI (XIP)
• Storage of voice, text, and data in space-constrained systems

Memory IC Procurement Notes

Verify the specific ordering suffix 'IQ' against official documentation to confirm exact package type and temperature grade. Confirm availability status as distributors may list obsolete or limited stock items. Ensure compatibility with 1.8V logic levels and TFBGA-24 footprint requirements before procurement.

Memory IC Selection Notes

Select this component for applications requiring low voltage operation between 1.7V and 1.95V. Consider the TFBGA-24 package for compact designs needing additional reset pins. Verify that the system supports Quad I/O modes if maximum transfer rates are required. Ensure thermal management aligns with the -40°C to +85°C industrial operating range.

Memory IC Part Context

The W25Q128JWCIQ belongs to the W25Q128JW series of SpiFlash memories designed for systems with limited space, pins, and power. This series offers performance exceeding ordinary serial flash devices through support for high-speed Dual and Quad SPI protocols. The family provides various packaging options to suit different board layout constraints while maintaining consistent electrical characteristics.

Memory IC Replacement Considerations

Check for W25Q128JV variants if 3.3V operation is acceptable. Verify pinout compatibility when substituting with other 24-ball TFBGA packages. Ensure substitute parts support the same 133MHz Quad I/O speed and 4KB uniform sector architecture.
