M25P16-VMN6P

STMicroelectronics
Legacy 16 Mbit SPI NOR family from ST that is commonly available for firmware storage use cases.

Overview

The M25P16-VMN6P is a 16 Mbit (2MB) Serial Flash memory device accessed via a high-speed SPI bus. It is a legacy storage solution from STMicroelectronics, designed for applications that require reliable non-volatile code storage and data logging with minimal pin count. The device operates on a 2.7V to 3.6V supply range and features a low-power standby mode for energy-efficient operation.

Why Choose This Part

This device offers a high-speed clock rate of up to 75MHz and features a deep power-down mode that reduces current consumption to 50uA. Its standard SO8N footprint and straightforward SPI interface ensure compatibility with a wide range of host controllers while maintaining a small PCB footprint.

Applications

Firmware Storage
Storing boot code and application firmware for microcontrollers and FPGAs.
Data Logging
Recording sensor data or event logs in industrial and consumer electronics.
Parameter Storage
Retaining user settings and calibration data across power cycles.
Look-up Tables
Storing large static data tables such as fonts or graphical assets for small displays.

Getting Started

Engineers can interface this memory with any MCU using a standard SPI peripheral and a single chip-select line. Development is often accelerated by using existing SPI Flash libraries (such as the SerialFlash library for Arduino or vendor-specific HALs) to manage sector erasing and page programming operations.
