The 71421SA20J8 is a high-speed 2K x 8 dual-port static RAM designed for asynchronous operation, suitable for both commercial and industrial applications. It features access times of 20 ns for commercial and 25 ns for industrial grades, making it suitable for applications requiring quick data retrieval. The device operates on a single 5V power supply and has a typical active power consumption of 325 mW, with a low standby power consumption of 5 mW. This memory chip includes internal interrupt logic for efficient interprocessor communication and supports independent, asynchronous access to memory locations from both ports. It is available in multiple package types, including 52-pin PLCC and 64-pin TQFP, and is capable of operating in an industrial temperature range of -40¬8C to +85¬8C. The device also offers battery backup operation with data retention at 2V for low-power versions. Engineers looking for a dual-port memory solution with low power consumption and fast access times may find the 71421SA20J8 suitable for their projects.
