The product has excellent features, including low operating current, high-speed random access, wide operating temperature and easy implementation with multiple logic devices. This component is used in devices such as computer peripherals and data entry devices, audio digital signal processors, mobile phones, tablet PCs, motion control systems, FPGAs, automotive ambient light sensors, 3D controllers for robotics and more.

Working Principle

AS7C4098A-12JIN is an 8-Mb static random access memory (SRAM) device that uses asynchronous logic. The chip contains 4 banks with 8K words, which have the same physical address but different data path. Each bank has two input ports (A, B) that are used to access data under the control of memory controller. Data is transferred using read and write operations during a single clock cycle. During a read operation, data is read from the memory location and transferred through port A or B. During a write operation, data is written to the memory location from either port A or B.The device is controlled by an external memory controller, and it uses a chip select signal to select either port A or B for data transfer. In addition, an address bus is used to specify the address of the memory location that is to be accessed. The device features read and write strobes that can be used to enable or disable data transfer from/to the memory. The device includes an extended hold time, which allows for increased hold times and fewer refresh cycles, thus improving system performance.

Conclusion

In conclusion, AS7C4098A-12JIN is an 8-Mbit SRAM device that is ideal for applications where multiple ports and fast throughput are needed. With its low-power, high-speed and extended hold time, this device is a great memory solution for many embedded, automotive, instrumentation and industrial automation applications.
