W25Q128BVEJP TR

Memory IC Overview

The W25Q128BVEJP TR is a 128M-bit (16M-byte) Serial Flash memory device manufactured by Winbond Electronics. It operates on a single 2.7V to 3.6V power supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 104MHz for Dual Output and 70MHz for Quad SPI. The device features a uniform sector architecture with 4KB sectors, 32KB blocks, and 64KB blocks. It includes advanced security features such as hardware write protection via the /WP pin, software lock-down, and a 64-bit unique serial number. The component is supplied in an 8-pad WSON 8x6-mm package.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes for high-speed data transfer and Execute In Place (XIP) operations.
• Provides flexible write protection through hardware /WP pin control and software-configurable block protect bits.
• Features a uniform erase architecture allowing granular management of 4KB sectors, 32KB blocks, and 64KB blocks.
• Includes a 64-bit unique serial number and Discoverable Parameters (SFDP) register for device identification.

Memory IC Applications

• Code shadowing to RAM for embedded systems
• Executing code directly from SPI bus (XIP)
• Storing voice, text, and data in space-constrained devices

Memory IC Procurement Notes

Verify the specific suffix 'EJP' against the manufacturer's official ordering information table to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before integration. Cross-reference the revision history to confirm the datasheet version matches the delivered components.

Memory IC Selection Notes

Select this component when a 128M-bit capacity is required with support for high-performance Quad SPI operations. It is suitable for applications needing low active current consumption and robust data retention characteristics. Consider the WSON-8 package for space-efficient designs requiring surface-mount technology.

Memory IC Part Context

This part belongs to the W25Q128BV family of SpiFlash memories, designed for systems with limited space, pins, and power. The series offers flexibility beyond ordinary Serial Flash devices, supporting various interface modes to optimize performance for different application requirements.

Memory IC Replacement Considerations

Check for W25Q128BV variants with different package codes (e.g., E for WSON, F for SOIC, B/C for TFBGA) if pinout or footprint adjustments are necessary. Verify that substitute parts maintain the same 2.7V-3.6V operating voltage and SPI interface compatibility.
