Introduction

72V811L10TF is an Application Specific Standard Product (ASSP), FIFO (First-In-First-Out) memory, developed by Renesas. It is intended to provide static memory management within an MCU (Microcontroller Unit) logical environment. As an application, the FIFO Memory holds data temporarily while the MCU processes the data sequentially. The FIFO Memory provides decentralized I/O communication interface control and sophisticated memory operations along with a large data buffer to buffer data while allowing rapid data transfers.

Application Field and Working Principle

The 72V811L10TF is designed for use in a variety of applications requiring static memory management. This includes applications in industrial, military, medical, and aerospace applications.The 72V811L10TF operates under a set of RAM access rules that ensure proper data storage and retrieval. When data is placed into or retrieved from the FIFO Memory, the read and write addresses are incremented or decremented to accommodate the current data access activity. At the same time, address pointers are monitored in both the read and write locations in order to ensure that the data is only accessed from one location at a time.The 72V811L10TF includes Read, Write, and Data Availability (D/A) logic. Read logic determines when data is to be read from the FIFO Memory, by comparing the current read address to the write address. Write logic ensures that data is only written to the FIFO Memory when the write address is greater than the read address. D/A logic monitors the amount of available data in the FIFO Memory and provides an empty/full status in order for the controller to adjust the data transmission parameters if necessary.The 72V811L10TF also includes an address auto-increment/decrement (A/I) logic. The A/I logic monitors the direction of the read and write operations, and will increment the read address or decrement the write address, depending on the direction of the data transfer. It will also reset the appropriate address when the FIFO Memory is full or empty.The 72V811L10TF is also designed to provide power savings when the memory is idle. In order to do this, the FIFO Memory is powered down while the MCU is idle, allowing the FIFO Memory to enter low-power standby mode.

Conclusion

The 72V811L10TF is an Application Specific Standard Product (ASSP) that provides static memory management within an MCU (Microcontroller Unit) logical environment. It is designed for use in a variety of applications requiring static memory management and provides sophisticated memory operations along with a large data buffer to buffer data while allowing rapid data transfers. Additionally, the 72V811L10TF is designed to provide power savings when memory is idle, making it an ideal memory solution for a variety of applications.
