72241L10JG

The 72241L10JG is an integrated circuit used to bridge communication between two buses which are operating at different speeds. Although similar to Direct Memory Access (DMA) devices, the 72241L10JG is a First-In, First-Out (FIFO) memory device. As opposed to DMA devices, FIFOs transfer data between buses more efficiently. It’s commonly used in communication applications, such as networking systems and inter-chip data transfer.

A FIFO is a type of memory buffer with two distinct parts: the input register and the output register. Data is stored in the input register which is written from an asynchronous data source. The output register is read by an asynchronous data sink. Data is shifted between these two registers with a consistent clock signal.

The 72241L10JG FIFO contains 64-deep input and output memories. It can store up to 128 bytes of data, allowing data transfer at variable speeds. Depending on the application, the FIFO can be configured as either four separate 16-deep FIFOs, two 32-deep FIFOs, or one 64-deep FIFO. This allows a designer to optimize the FIFO for their specific design.

The 72241L10JG also includes a write control signal that can be used to control the flow of data. This control signal allows the user to pause the data transfer by activating the FIFO ’s input flow control signal and halting data transfer. This can help to prevent data overflow and is useful when the speed of the input and output devices are wildly different.

The 72241L10JG FIFO also includes two additional signals called data ready and data valid. The data ready signal notifies the user when there is new data in the input register. The data valid signal notifies the user when there is valid data in the output register for the user to read. This can be useful for applications where data must be read in a timely manner.

The FIFO is a low-power device, with a typical power consumption of around 100mA. It also has a wide operating voltage range, from 2.5V to 3.6V. This makes it compatible with many power sources, including most standard battery-operated devices.

In summary, the 72241L10JG is an ideal choice for memory bridging and bus communication applications where data must be transferred between two different speed buses. It’s a low-power, reliable, and versatile device that can be configured to optimize data transfer speed and performance for a wide variety of applications.
