The 71321LA20PF is a high-speed 2K x 8 dual-port static RAM designed for asynchronous memory applications. It features a maximum access time of 20 ns for commercial applications and operates with a typical power consumption of 325 mW during active use and 1 mW in standby mode. This memory device supports independent, asynchronous access for reads and writes, making it suitable for interprocessor communications. It includes internal interrupt logic and can be configured as a master or slave in multi-port systems, allowing for easy expansion of data bus width. The device is compatible with a single 5V power supply and is available in various package types, including 52-pin PLCC and 64-pin TQFP. Additionally, it offers battery backup operation with 2V data retention capability, making it suitable for low-power applications. The industrial temperature range for this part is -40°C to +85°C, ensuring reliability in demanding environments.
