AT25DF641A-SH-T Integrated Circuits (ICs)

AT25DF641A-SH-T is a non-volatile memory that establishes an impressive balance between cost, performance, and power efficiency. Memory is the most crucial element in any data processing system, and the AT25DF641A-SH-T provides the performance and reliability required for various embedded applications.

The AT25DF641A-SH-T is organized as 8192 sectors of 64 bytes or 512 bytes each. It uses a standard 8-pin SOIC package and provides a simple 3-byte instruction set and features a single-pin Serial Peripheral Interface (SPI) connection. Operating at speeds of up to 20MHz, the AT25DF641A-SH-T provides a fast page write cycle time of 1.5 ms.

The AT25DF641A-SH-T has two memory organization modes: sector erase and block erase. The sector mode can erase selected sectors in the range of 64-byte or 512-byte intervals while the block mode can erase 128-, 256-, or 512-byte ranges. A unique feature of this memory device is the protection granularity setting. This feature ensures that data stored on the memory is protected from accidental overwrites and erasures.

Another important feature of the AT25DF641A-SH-T is its advanced write protection scheme. The device has four write protect options, including hardware write protection, hardware write protection for the entire memory, and software write protection. When protecting the entire memory, the AT25DF641A-SH-T provides two levels of protection; either to a full memory sector or the entire device.

In terms of power consumption, the AT25DF641A-SH-T is a low-power device, as it consumes less than 10 mW during normal operations. It also has an Auto Power-down Mode that consumes only 100 nA when in standby mode. This feature ensures that the device does not draw excessive power when not in use. Additionally, the low power consumption makes the AT25DF641A-SH-T suitable for battery-powered applications.

The main application for the AT25DF641A-SH-T is to provide reliable non-volatile memory for embedded applications. The device is typically used in applications such as data logging and data buffering, code storage and execution, and system configuration data storage.

In conclusion, the AT25DF641A-SH-T is a low-cost and low-power memory device that provides reliable and reliable performance and write protection for embedded applications. Its sector and block erase modes, advanced write protection features, and low-power standby mode make it an ideal solution for embedded applications that require reliable and safe non-volatile memory.
