                                                72841L15TF Overview
The 64-LQFP  package contains FIFO memory chip.It's packaged in the shape of a Tray .There is a 72K 4K x 9 x 2 MB memory on the FIFO chips, which can be used to store both applications and data.The temperature should be adjusted to 0°C~70°C in order to ensure reliable operation.It is mounted in the Surface Mount position.It uses a supply voltage of 4.5V~5.5V  to operate.The 7200 series contains this memory logic.As far as operating current is concerned, it has a maximum of 60mA .I believe it belongs to the 72841 family of numbers.
