AT25SF041-SSHDHR-T is an SPI flash memory device with high storage density and fast random read performance. It features a 4-wire SPI serial interface and a 2-wire Ultra-Low-Power (ULP) interface. The device is available in a 4Kb or 8Kb flash array and provides erase, program and read functions.

The device is ideal for applications where low-power consumption and fast data access are critical. It can be used in a variety of consumer, industrial and automotive applications, such as in-car audio systems, access control systems, navigation systems, consumer devices, and industrial equipment.

The AT25SF041-SSHDHR-T is offered in small packages and is ideal for applications where board space is limited. It also offers extended temperature range, up to 125 °C, which makes it suitable for use in harsh industrial and automotive environments.

The device is operable at voltages from 2.7 V to 3.6 V and offers power saving modes, including advanced sleep entry. The device has an on-board SHA-256 block for securely storing data and can be programmed to execute specific code when power is applied.

The AT25SF041-SSHDHR-T is built on an advanced CMOS process, providing low power consumption, an ultra-small footprint, and fast data transfer speed. It features high cycle endurance, data retention of up to 25 years, and operating temperature range of -40°C to 85°C.

The working principle of the AT25SF041-SSHDHR-T is based on EEPROM technology. Data is stored in an array of seperate memory cells that are connected to a control logic circuit. The logic circuit is used to control the charge state of the cells, which determines whether the stored data bit is a 0 or a 1. The data stored in the cells is retained as long as power is applied to the device.

When the device is programmed, the control logic circuit first evaluates the data being sent to the memory cell and then charges or discharges the internal memory cell accordingly. The control logic circuit also reads the data from the cells, which allows for fast, low-power data access.

The AT25SF041-SSHDHR-T is designed for use in applications that require a reliable, low-power memory device. The advanced design provides fast data access, low power consumption and extended temperature range, making it an ideal device for a variety of consumer, industrial and automotive applications.
