Logic FIFOs Memories are becoming increasingly important today, due to the growth of embedded systems employing processors and memory devices. The 72255LA15TFI Application Field and Working Principle is one such Logic FIFOs Memory component, which is designed to help embedded systems interact with memory, bus interfaces, and peripherals.

The 72255LA15TFI is a Logical Circuit Memory component with a unique array architecture. It supports up to 16 double-byte data words, with a maximum of 65535 16-bit data elements. Data elements are written sequentially and can be freely accessed for read and write operations. The component is an asynchronous device, meaning that reads and writes are initiated by an external signal, and no clock signal is required.

The 72255LA15TFI is designed for use in a variety of embedded applications. It is ideal for use in memory-mapped peripherals, such as video output or coprocessors, as well as for communication bridges between processors and peripherals. The component is designed to provide a high-speed pathway for devices to exchange data, meaning that it can be used to off-load the processor from tedious data-transfer tasks. Additionally, it has built-in error-correcting codes, allowing devices to make sure that data is transferred reliably, even in the event of noise or interference.

What sets the 72255LA15TFI apart from other Logical Circuit Memories is its unique array architecture. The component is organized into two independent double-byte banks, allowing simultaneous write and read operations. Additionally, the component is designed to support up to 16 double-byte words, meaning that it is possible to store up to 65535 16-bit data elements. This allows for easy addressing and data transfer, as well as reliable transactions.

The 72255LA15TFI uses a three-signal write system for write operations. The first signal is the address input, which is the address of the data element that is currently being transferred. The second signal is the data-in signal, which is the data that is to be written. The third signal is the write-enable signal, which is set high to indicate that data should be written to memory. Similarly, the component uses a three-signal read system for read operations. The first signal is the address input, which is the address of the data element that is currently being read. The second signal is the data-out signal, which is the data that is read from memory. The third signal is the read-enable signal, which is set high to indicate that data should be read from memory.

The 72255LA15TFI also features built-in fault protection for data transfers. It is designed with a number of error-checking features, such as read-byte detection and byte-write detection, to ensure the reliability of data transfer. Additionally, the component also supports an optional parity-check bit-by-bit error detection code, providing additional protection against transmission errors. This ensures that any data that is read or written is reliable and accurate.

In summary, the 72255LA15TFI Application Field and Working Principle is a powerful, yet flexible Logical Circuit Memory component. It supports up to 16 double-byte words, with a maximum of 65535 16-bit data elements, and offers reliable read and write operations. Its three-signal write and read systems make it easy to address and transfer data, and the component also features built-in fault protection for data transfers. This makes it an ideal choice for a variety of applications, such as memory-mapped peripherals and communication bridges between processors and peripherals.
