Working Principle

The AS4C256M8D3-12BIN is an asynchronous static random access memory (SRAM) component. This product features a static DRAM macrocell and input/output buffers that are optimized for low power consumption. It operates using the asynchronous protocol, meaning that the device clock can be on or off and will still function properly. The AS4C256M8D3-12BIN enables faster read access than traditional DRAM solutions, as it stores data in a static memory cell and does not require time for a refresh cycle.

The AS4C256M8D3-12BIN is optimized for applications that require low power consumption and wide range of operating temperatures. This product has an asynchronous page mode read of 15ns and a fast random access time of 80ns, which improves performance and reduces power consumption. It also provides better EMI/EMC performance and improved signal integrity for high speed designs. In addition, this product is equipped with circuit protection features such as a watchdog timer and built-in write-protect function.

Conclusion

The AS4C256M8D3-12BIN is a 4Mbit x 16-bit (256K x 16-bit) synchronous SRAM product, perfect for applications in need of low power consumptions and wide range of temperature operations. This product offers excellent random access time and asynchronous page mode read, making it suitable for many designs such as microcontroller-based products, DSPs, data communications systems, and industrial automation networks. Furthermore, it is equipped with a write-protect function and enhanced circuit protection features, providing better EMI/EMC performance and improved signal integrity.
