The M27C4002-10F1 is a high-density, electrically erasable programmable read-only memory (EEPROM) designed for applications that require reliable storage and easy reprogramming of data. It is a member of the M27C family of memories, and is based on silicon-gate CMOS technology. It is available in several versions, which differ in terms of package type, access time and operating temperature range.

Application field

The M27C4002-10F1 is primarily used for microcontrollers and other embedded systems applications. The device is suitable for a wide range of applications, including automotive, instrumentation, medical, point-of-sale, industrial control, and communications. Its features make it ideal for demanding applications where cost and space are important considerations.

The device can be used as a form of non-volatile programmable memory, allowing it to store and protect data in the event of a power failure. It can also be used as a persistent storage device, such as a library of code or lookup tables. As the program code is easily reprogrammable, the M27C4002-10F1 can also be used in situations where firmware changes may need to be implemented quickly and easily.

Working principle

The M27C4002-10F1 is a 256Kb device organized as 32,768 x 8 bits, with a typical access time of 55ns. The device has an extensive array of control and status signals, enabling the user to read and write data, as well as program, erase and protect it. This makes the device suitable for a variety of applications.

The device is organized as eight blocks, each comprising 32Kb. To program the device, the user must first select the desired block by setting the corresponding block select signal. Programming is then achieved by writing the data to the device in the appropriate location in the selected block. To erase the device, the user sets the block select signal and erases the entire block at once. The device can also be protected, preventing unauthorized modification of the stored data.

The device uses high-speed CMOS circuitry, allowing it to achieve a typical access time of 55ns. The device is further optimized to reduce power consumption and extend the life of the device. This makes it suitable for battery-powered applications, where low power consumption is a key requirement.

The M27C4002-10F1 can be packaged in a variety of types. The most commonly used package types are DIP and PLCC, although the device can also be ordered in a Wafer, LCC or TSSOP package. The device is also available in a range of temperatures, making it suitable for use in extreme temperature environments.

In summary, the M27C4002-10F1 is a high-density, electrically erasable programmable read-only memory suitable for a variety of applications. Its features, including fast access time and low power consumption, make it an attractive choice for cost-sensitive and space-constrained projects.
