Introduction

The 72V253L6BC is a FIFO (First In First Out) type memory device.FIFO stores for multi-bit wide word space of data. It can be used in the application filed of multiplexers, data buffers, and data transmission buses. FIFO is usually used to avoid data send overflow or receive data underflow. 72V253L6BC device along with other FIFOs is to provide a buffer between two parts of digital system which are not able to communicate with each other due to speed differences.

Application Field

The 72V253L6BC is a 32K × 8 bit FIFO that holds 128 byte blocks. It is an advanced CMOS Static Random Access Memory (SRAM) with FIFO architecture and enables efficient data transfer between two asynchronous nodes.The 72V253L6BC memory device is mainly used in the filed of multiplexing and timing skew control. In a multiplexer application, it is used to provide data buffering to make the interface between two different speed clocks or serial ports. It operates as a timing skew control device to make sure the outgoing data is the same as the incoming data. In addition, it can also be used in data transmission busses. FIFO\'s are used to couple data bus arbitration with data transfer. Data channels with different speeds can be connected using FIFO as desired.

working principle

In digital logic system, the 72V253L6BC seeks to efficiently transfer data between two asynchronous nodes. It allows one memory device to be connected to two different clock domains. In the first clock domain, the data is written to the memory and in the second clock domain, the data is read from the memory. The 72V253L6BC works as a buffer between the two clock domains.The working of the device is based on the concept of level-sensitive memory. The device has two independent memory banks. The input data is written to the first bank and the second bank is used to read the data. The device has two internal state machines.The write state machine handles the write transactions and the read state machine handles the read transactions.When data is written, the first memory bank is loaded with the data and the write pointer is incremented. When data is read, the second bank is loaded with the data from the first bank and the read pointer is incremented. This way the data is read from the FIFO in the same order as it was written.

Conclusion

The 72V253L6BC memory device is a FIFO with integrated level-sensitive memory. It is used to transfer data between two asynchronous clocks. It is mainly used in the application filed of multiplexers, data buffers, and data transmission busses. The working principle of the 72V253L6BC involves two independent memory banks and two internal state machines. The first memory bank is used to write the data, while the second bank is used to read the data. The device is designed to ensure that the data is read from the FIFO in the same order as it was written.
