W25Q128JVSIQ
Overview
The W25Q128JVSIQ is a 128Mbit serial Flash memory IC that provides a high-performance alternative to standard Parallel Flash memories for space-constrained designs. It operates on a single 2.7V to 3.6V power supply and supports standard SPI as well as Dual and Quad I/O SPI at clock speeds up to 133 MHz. This device is organized into 16,384,256 bytes and features a flexible architecture with 4KB sectors, making it efficient for applications that require frequent data updates.
Why Choose This Part
This memory offers a high performance throughput of up to 133 MHz, effectively reaching 532 MHz (66 MB/s) when using Quad SPI mode. The 4KB sector erase architecture allows for granular memory management and more efficient updates compared to larger block-erase devices. It also features a low standby current of 10uA and advanced security features including software and hardware write protection.
Applications
Key Specifications
Getting Started
Engineers can interface this IC with any MCU supporting SPI, Dual SPI, or Quad SPI peripherals; logic levels must be kept within the 2.7V to 3.6V range. To begin development, verify the 8-SOIC (208-mil) footprint on your PCB and ensure your firmware driver supports the standard Winbond instruction set. Hardware and software reset functions are available to ensure reliable system recovery during power cycles or execution errors.
