72285L15PF8 Application Field and Working Principle

The 72285L15PF8, which has the function of a FIFO memory or a first-in-first-out (FIFO) memory, is designed to store a specific amount of data values by combining the registers, encoders and decoders. It is used in a variety of applications such as industrial automation, consumer electronics, telecommunications and so on. Basically, the basic structure of a FIFO memory consists of two memories, one for the storage of the data and the other for the retrieval of the data, the input and output of the data is controlled by two registers.

The 72285L15PF8 is a parallel-in-parallel-out (PIPO) FIFO memory, which means that data is written into the device and read out of the device at the same time. The PIPO design provides higher speed read and write operations compared with the serial-in-parallel-out (SIPO) FIFO memory. The 72285L15PF8 FIFO has a read access time of 2.5ns and a write access time of 5ns. The 72285L15PF8 FIFO also has a data output latch which is designed to track the data input as it is written. It also provides a data output enable signal to indicate the validity of the data being read out.

The 72285L15PF8 FIFO provides bidirectional parallel data I/O for 16 bits of addressable data. The device has non-inverting and inverting bidirectional output data buffers which can be used in either parallel or serial mode. The device also has 4 multiplexed input and output pins to allow for flexible data configurations. In addition, the device has an asynchronous clear register (ACR) pin which controls the data input and output.

In terms of working principle, the 72285L15PF8 FIFO uses a First In, First Out (FIFO) algorithm to store data. Data is written into the device one bit at a time and read out in order of original storage. This FIFO implementation allows for data to be stored and read out quickly. As well, the built-in address margin protection technology ensures that data will not be overwritten during read operations. The 72285L15PF8 also has three on-chip complementary metal-oxide-semiconductor (CMOS) pulse-width-modulation (PWM) counters, which are used to protect the data from any write violations.

In conclusion, the 72285L15PF8 FIFO memory is widely used in various fields, such as industrial automation, consumer electronics, telecommunications and so on. Its parallel-in-parallel-out design allows for faster read and write operations, while its first-in-first-out algorithm guarantees reliable data storage and retrieval. It also employs on-chip CMOS PWM counters to protect against any write violations. Lastly, the data output enable signal indicates the validity of the data being read out.
