Overview

The W25Q128JVSIM is a 128Mbit serial NOR Flash memory supporting high-performance SPI, Dual SPI, Quad SPI, and QPI interfaces. Operating at up to 133MHz with Double Transfer Rate (DTR) support, it provides fast data access and efficient code execution-in-place (XiP) for embedded systems.

Why Choose This Part

The device features a flexible architecture with 4KB sectors for efficient memory management and supports 133MHz clock speeds for high throughput. It includes security features like a 64-bit unique ID, OTP security registers, and hardware write protection to safeguard sensitive firmware.

Applications

Microcontroller Code Storage
Storing firmware and application code for MCUs that lack sufficient internal flash or require external execution-in-place.
FPGA Configuration
Holding bitstream data to configure FPGAs during power-up sequences.
Data Logging
Reliable non-volatile storage for sensor logs, system event history, and configuration parameters.
IoT Edge Devices
Low-power storage for connected devices requiring secure OTA firmware updates and small footprint footprints.
