FLASH - NOR Memory IC 16Mbit SPI - Quad I/O 133 MHz 8-SOIC
Active

Overview

The W25Q16JVSSIQ is a 16Mbit (2MB) serial Flash memory supporting Standard SPI, Dual SPI, and Quad SPI interfaces. It operates on a single 2.7V to 3.6V power supply and achieves high-speed performance with a 133MHz clock rate, enabling equivalent rates of 532MHz when using Quad SPI. This NOR flash is designed for systems with limited space, pins, and power requirements.

Why Choose This Part

It offers exceptional performance for its footprint, featuring a 133MHz clock and Quad I/O capability that significantly reduces boot times compared to standard serial flash. The device includes robust security features like a 64-bit unique ID and OTP security registers, while maintaining a low 1uA power-down current for battery-sensitive designs.

Applications

Microcontroller Code Shadowing
Storing executable firmware that is shadowed to RAM at boot for high-speed execution in embedded systems.
Parameter Storage
Retaining non-volatile configuration data, calibration constants, and lookup tables that require periodic updates.
Data Logging
Recording system logs and sensor data in low-power IoT devices or industrial controllers.

Getting Started

Interface this memory to an MCU using the SPI bus; for maximum throughput, ensure your controller supports Quad SPI (QSPI) peripheral modes. Developers can use standard SPI libraries and should reference the SFDP (Serial Flash Discoverable Parameters) register to automatically identify device capacity and timing requirements.
