The M27C4001-12F6 is a type of non-volatile EPROM, produced by ST Microelectronics. It is a 4Mbit device that is capable of storing up to 16Mbits of data. The device is commonly used in industrial applications and is available in a range of different packages.

Application Field: The M27C4001-12F6 is typically used in applications requiring reliable data storage and the ability to retain data with no power supply. It is ideal for automotive, medical, industrial and consumer applications. Additionally, the device is well suited for embedded applications, such as in microcontrollers, set-top boxes, and home entertainment systems.

Working Principle: The M27C4001-12F6 operates on a non-volatile memory technology known as floating-gate EEPROM. This technology uses an array of transistors to store data in the form of electrical charge. Data is stored on the device until it is erased, at which point the charge will dissipate and the stored data is lost. The device uses a high-voltage pulse to write and erase data. The data can be read by applying different combinations of read and control signals to the device.

At the heart of the M27C4001-12F6 lies an internal data array composed of four million floating-gate transistors. These transistors are divided into 8 blocks of 8K bits, each block containing 1024 pages of 8 bits. The device can store up to 4 Megabit of data and has an operating temperature range of -40°C to +85°C. The data retention time is typically 10 years at 25°C.

The M27C4001-12F6 is an ideal choice for applications requiring reliable data storage and the ability to retain data with no power supply. The device is able to read and write data quickly and is suitable for a variety of different operating environments. It is an important component in many embedded applications and is the perfect choice for projects requiring a reliable, long-term data storage solution.
