Logic - FIFOs Memory: 72V2111L15PFGI Application Field and Working Principle

The 72V2111L15PFGI is a FIFO (First-In First-Out) memory IC device from Silicon Valley Microelectronics. This device is used in a wide variety of application fields such as embedded, industrial, automotive and communications. It is suitable for use in applications not requiring high speed memories.

FIFOs are memory devices with associated logic that provide a controlled way to store and retrieve data. Data is written to the FIFO first-in first-out (FIFO) and is read out in the same order. The 72V2111L15PFGI is a dual channel 1-port FIFO. It is suitable for applications with two independent data channels where buffering is required. The device can store up to 720 bytes of data.

Working Principle

The 72V2111L15PFGI operates with an internal write clock and read clock. It also has an asynchronous reset and sense circuitry on the write and read ports. Data is presented to the write port of the device and the FIFO logic determines whether the data will be stored or discarded based on its internal logic. This logic ensures that the FIFO is in a valid operational state at all times.

The read port of the device is used to retrieve the data. The data is read out with a selectable delay. The data output rate is determined by the read clock frequency. The FIFO has an internal control circuit that ensures that the data is always read out in the correct order.

The device has a selectable FIFO size of 512 or 720 bytes. It supports two logical independent channels, each with its own write and read ports. This allows two independent data streams to be buffered in the FIFO. The FIFO also has sense logic inputs to detect when the FIFO is full or empty.

The device has wide operating temperature range and is available in a 14-pin plastic DIP package. It has a supply voltage range of 3.3V to 10V.

The 72V2111L15PFGI is an ideal choice for applications that require data buffering and reliable FIFO operations. With its wide operating temperature range and multiple data channels, it is highly suitable for embedded, automotive, industrial, and communications applications.
