Upgrade your storage with the W25Q128JV 128M-bit Serial Flash Memory. High-speed SPI, Dual/Quad I/O, and QPI support for reliable, fast data performance.
Description
The W25Q128JV is a high-performance 128M-bit (16M-byte) Serial Flash memory designed for systems where space, pin count, and power consumption are limited. This versatile chip offers performance far beyond standard serial flash, making it an excellent choice for code shadowing to RAM or running code directly from the memory (Execute In Place). It operates on a single 2.7V to 3.6V power supply and is incredibly efficient, consuming as little as 1µA during power-down mode. Its flexible architecture allows you to erase data in small 4KB sectors or larger blocks, providing great precision for data and parameter storage.
Features
High Capacity: 128M-bit (16M-byte) total storage organized into 65,536 programmable pages.
Superior Speed: Supports SPI clock frequencies up to 133MHz, reaching equivalent rates of 532MHz for Quad I/O.
Flexible I/O: Supports Standard SPI, Dual/Quad SPI, QPI, and Double Transfer Rate (DTR) for ultra-fast data transfer.
Low Power Consumption: Optimized for battery-powered devices with a tiny 1µA power-down current.
Efficient Operation: "Continuous Read" mode allows for faster memory access with minimal instruction overhead.
Durable Design: Rated for 100,000 program-erase cycles and over 20 years of data retention.
Advanced Security: Includes a 64-bit unique ID, individual block/sector locks, and write protection features to keep your data safe.
Applications
Code Shadowing: Loading firmware or operating systems into RAM for faster execution.
Execute In Place (XIP): Running software directly from the flash memory to save system RAM.
Data Logging: Storing sensor data, voice recordings, or text files in portable devices.
Parameter Storage: Storing system settings and calibration data using its small 4KB erasable sectors.
Consumer Electronics: Ideal for smartphones, tablets, and smart home gadgets that need compact, fast storage.
