The AS7C4098A-12TCN is a high-speed, low-power dual-port Static Random Access Memory (SRAM) developed by Alliance Memory. It is specifically made for complex system applications with space-constrained conditions such as instrumentation, medical, defense and aerospace and provides particularly efficient high-speed access to nonvolatile memory. This article will explore the application field of the AS7C4098A-12TCN, as well as its underlying working principles.

Application Field

The AS7C4098A-12TCN, with its low power, high speed operation and simple interface, is capable of addressing the requirements of complex system applications that feature space-constrained conditions. Its design is based on memory-manager architecture, and its small 8-pin Plastic Small Outline Integrated Circuit (SOIC) package makes it suitable for instrumentation, medical, defense and aerospace applications.

This device also features a wide range of features and capabilities that make it suitable for many different types of applications. It is built with a low internal power dissipation of 25 mW at a maximum clock frequency of 10 MHz and a supply voltage of 4.5 V. Additionally, it features two 4-bit ports, with synchronous page and word accesses, that offer up to 80 ns access times. This allows the AS7C4098A-12TCN to provide high-speed access to nonvolatile memory with minimal power consumption and simple user control.

Working Principle

The working principle of the AS7C4098A-12TCN is based on Single Ended Input/Output (SEI/O) memory-manager architecture and is able to provide fast access times of up to 80 ns. The architecture is designed to accommodate multiple types of accesses by providing the necessary logic for addressing and data retrieval. In the SEI/O architecture, each memory access has a username and address associated with it. The username is written to the memory manager, and then the address associated with the username is written to the address bus. Once the address is written, the appropriate data is read from the data bus.

The memory manager is responsible for providing all the necessary operations to access the memory as well as controlling the timing of the operation. It contains logic to mask the address bus, check for valid addresses and determine the type of access being made. It also generates the necessary control signals to perform the various read and write operations. The memory manager allows multiple operations to be performed in parallel, allowing applications to access multiple types of data in less time.

The AS7C4098A-12TCN also features two 4-bit ports that can be used to access different areas of the memory. The ports are designed to be synchronous, with each port being able to perform separate read and write operations. This allows for fast access times of up to 80 ns for both reads and writes. Additionally, the ports can be used together for a single operation, allowing for faster access times and improved bandwidth.

Conclusion

The AS7C4098A-12TCN is a high-speed, low-power SRAM that can be used in a wide variety of applications. Its small 8-pin SOIC package and memory-manager architecture allow it to meet the needs of space-constrained applications. Its two 4-bit ports offer fast access times of up to 80 ns, as well as the ability to perform multiple operations in parallel, making it suitable for instrumentation, medical, defense and aerospace applications. Finally, the device is designed to offer low power consumption and a simple user control, making it suitable for a variety of applications.
