W25Q128JWBIQ

Memory IC Overview

The W25Q128JWBIQ 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 sector erase architecture, 100K program-erase cycles, and over 20-year data retention. It includes advanced security features such as hardware write protection, individual block/sector locks, and a 64-bit unique ID. The component is housed in a 24-ball TFBGA package measuring 8x6mm.

Memory IC Feature Summary

• Supports high-speed Quad I/O SPI operations for direct code execution (XIP).
• Provides flexible memory organization with uniform 4KB sectors and 32KB/64KB blocks.
• Integrates comprehensive hardware and software write protection mechanisms.
• Features low active current consumption and deep power-down modes.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'IQ' against official manufacturer documentation to confirm exact temperature grade and packaging specifications. Ensure compatibility with the required 1.7V-1.95V supply voltage range for your system design. Confirm that the 24-ball TFBGA package dimensions align with your PCB layout constraints. Check for any special ordering requirements or lead times directly with Winbond Electronics distributors.

Memory IC Selection Notes

Select this component when a 128M-bit capacity is required within a compact 24-ball TFBGA footprint. It is suitable for applications demanding low voltage operation around 1.8V. Consider this part if hardware write protection and individual sector locking are necessary for data integrity. Ensure the host controller supports Quad I/O SPI protocols to utilize the full performance capabilities of the device.

Memory IC Part Context

This component belongs to the W25Q128JW series of SpiFlash memories designed for industrial and industrial plus grades. The series offers flexibility and performance exceeding ordinary serial flash devices. It is optimized for systems with limited space, pins, and power budgets. The W25Q128JW family provides various package options including SOIC, WSON, and TFBGA to suit different assembly needs.

Memory IC Replacement Considerations

Consult official Winbond documentation for verified substitute part numbers. Cross-referencing should be performed based on pin compatibility, voltage levels, and interface support.
