72605L25PF8

72605L25PF8 is an asynchronous first in, first out (FIFO) memory device from Texas Instruments. The device is ideal for applications such as data buffering, protocol conversion and communication interface bridging. This memory device separates data input and data output with separate address spaces, allowing simultaneous read and write operations with no data corruption.

When used as an FIFO, the device allows data to be stored in order of arrival and also allows for accurate sequencing and time stamping of stored data. It is widely used in mission-critical applications such as military and aerospace where time-stamping of data is of paramount importance. Additionally, the device provides the necessary logic to return an empty flag when the FIFO is empty and a full flag when the FIFO is full.

The 72605L25PF8 device is available in a 22-lead plastic package with an operating temperature range of -55°C to +125°C. It is suitable for a wide range of applications due to its high data transfer rates, low latency times and flexibility.

The 72605L25PF8 device operates in two modes – Asynchronous Store mode and Synchronous Store mode. In the Asynchronous Store mode, the device can store data at speeds up to 40 MHz with a latency time of 14 nanoseconds. In the Synchronous Store mode, the device can store data at speeds up to 80 MHz with a latency time of 10 nanoseconds.

The device consists of two parts: a data register and a controller.The data register stores the data that is to be read and written, while the controller governs the operation and timing of the device. It is responsible for initiating reads, writes and data transfer and also for enforcing address sequencing.The device is configured through a group of control pins that provide information about a read/write sequence, data size, write enable and clock frequency.The device also includes a FIFO Full flag output pin, which signals when the device has reached its maximum storage capacity; a FIFO Empty flag output pin, which indicates that the FIFO is empty; and an Empty/Full flag input pin, which is used to reset the device and empty the FIFO.

In summary, the 72605L25PF8 is a highly reliable and flexible memory device that is able to store data at speeds up to 80 MHz with a latency time of 10 nanoseconds. It is ideal for applications such as buffering, protocol conversion, communication interfacing and time-stamping. Its two-part structure, consisting of a data register and a controller, provide a high level of flexibility and functionality. The device also provides a FIFO full/empty flag output, enabling accurate data control and sequencing.
