Logic-FIFOs memory is a type of memory used to store large amounts of data on a digital medium. The 72V85L15PA is a logic-FIFOs memory device designed for use with low-speed logic devices and microcontroller-based systems.The 72V85L15PA device has two separate functions. The first is an address-based data store that can hold up to sixteen 16-bit words. It uses an asynchronous address bus and data bus for data storage. This data store can also be addressed for reading, writing, and copying operations. The second function is a FIFO buffer that can hold up to fifteen 8-bit words. This is used to buffer data in order to increase the speed of data transfer between a microcontroller and other slower devices.The 72V85L15PA can be used to interface with both synchronous and asynchronous memory devices. Its main application field is to be used as an interface between a microcontroller and other logic devices, such as external memory devices or logic devices that operate at significantly different speeds than the microcontroller. It can also be used in memory mapped Input/Output (I/O) designs as well as multiport memory architectures.The working principle of the 72V85L15PA is straightforward. The device is supplied with a power supply, address and data buses, and control signals. The address bus is used to select the memory location the data is to be stored or retrieved from, while the data bus is used to transfer the data between the device and the logic device. The control signals are used to control the direction and timing of the data transfer.The 72V85L15PA is optimized for low-power operation, and it can be operated from either a 5V or 3.3V supply. The device has a low standby current consumption and a high bus access speed. It also supports a dual port access for simultaneous read and write operations to ensure data integrity during data transfer.In summary, the 72V85L15PA is a logic-FIFOs memory device designed for use with low-speed logic devices and microcontroller-based systems. It has two separate functions, an address-based data store and a FIFO buffer, and is optimized for low-power operation. It can be used to interface with both synchronous and asynchronous memory devices, and is used in a range of applications from memory mapped I/O designs to multiport memory architectures.
