W25Q128FVPBQ

Memory IC Overview

The W25Q128FVPBQ is a 128-Mbit (16M x 8) Serial Flash memory component manufactured by Winbond Electronics. It operates within a voltage range of 2.7V to 3.6V and supports SPI, Dual/Quad SPI, and QPI interfaces with a clock frequency of 104 MHz. The device features an array organized into 65,536 programmable pages of 256 bytes each, supporting sector, block, and chip erase operations. It is housed in an 8-pin VFBGA package measuring 6x8 mm and functions across a temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports standard SPI, Dual SPI, Quad SPI, and QPI modes for flexible interface options
• Includes hardware write protection via dedicated pins and software-configurable security registers
• Features a 64-bit unique serial number for individual device identification
• Provides high-speed data access through Quad I/O and QPI protocols

Memory IC Applications

• Code shadowing to RAM
• Executing code directly from flash (XIP)
• Storing voice, text, and data parameters
• Embedded systems requiring non-volatile storage

Memory IC Procurement Notes

Verify the specific suffix 'PBQ' against official manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and check for any Product Change Notifications (PCN) regarding manufacturing site or material changes before finalizing procurement plans.

Memory IC Selection Notes

Select this component when space-constrained designs require 128-Mbit capacity in a compact VFBGA footprint. Ensure the system controller supports the required SPI modes and that the operating voltage aligns with the 2.7V to 3.6V specification. Consider thermal requirements if the application operates near the upper temperature limit.

Memory IC Part Context

This part belongs to the W25Q128FV series of SpiFlash memories designed for performance and flexibility. It serves as a non-volatile storage solution for embedded applications, offering advantages over ordinary serial flash devices through higher clock speeds and advanced write protection features.

Memory IC Replacement Considerations

Direct substitutes include other W25Q128 variants with compatible packages, such as W25Q128JVSIQ (SOIC-8) or W25Q128JVSIM (SOIC-8), provided the physical footprint allows for adaptation. Verify electrical characteristics and pin assignments carefully.
