Memory

The AT25SF041-MHD-T is a 4Mbit (512KB × 8) Serial Flash memory, mainly used in industrial, IoT and automotive applications. By combining the advanced CMOS process technology, the ability to program, erase, and read over a million times, the single-contact four-wire serial interface and tiny memory footprint, these features enable it to serve as an ideal solution for most embedded applications, providing a high level of flexibility and performance.

The AT25SF041-MHD-T Serial Flash memory uses a standard four-wire (SPI) serial interface for programming, erasing, and reading. It is organized as 512K words of 8 bits each. It provides accessible operations such as sector erase, chip erase, write and read, with low-voltage programming, program/erase suspend, and companion cells for advanced features such as configuration block unlock. It has an on-board voltage monitor and selectable write protect. Additionally, it is also available in an industrial temperature range of -40°C to 85°C.

The AT25SF041-MHD-T Serial Flash memory provides a flexible memory solution ideal for most embedded application needs, including current and next-generation microcontrollers, complex logic, computing platforms, and automotive applications. Its size and wireless programming make it the ideal companion to these devices, providing the ideal solution for storing strong code and data. Its small form factor also makes it ideal for applications that need to store large amounts of data and/or code in a small footprint.

The working principle of the AT25SF041-MHD-T Serial Flash memory is based on the same principles as other types of non-volatile memory, such as EEPROM and flash. Non-volatile memory is an integrated circuit that stores data in a non-volatile form, meaning the data remains even when the power is turned off. In the case of the AT25SF041-MHD-T Serial Flash memory, the device uses charge trapping technology to trap and store charge on the floating gate of a MOSFET transistor in the chip. This stored charge provides the mechanism for storing the data. To program or erase the memory, the AT25SF041-MHD-T Serial Flash memory applies a high voltage to the memory cell to create an avalanche break down and is then able to write or erase the data.

The AT25SF041-MHD-T Serial Flash memory is available in various packages, with support for various interface operations such as sector erase, chip erase, write and read, program/erase suspend, and companion cells for advanced features such as configuration block unlock. The device is also available in a small form factor, making it ideal for many applications such as programming of microcontrollers and other embedded devices, especially those that need to store large amounts of data and code in a small footprint.
