The 71421LA55J8 is a high-speed 2K x 8 dual-port static RAM designed for asynchronous memory applications. It features a maximum access time of 55 ns 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 used in conjunction with the IDT71321 as a master device to expand data bus width. The device is compatible with a single 5V ¬±10% power supply and is available in multiple package types, including 52-pin PLCC and 64-pin TQFP. Additionally, the low-power version offers battery backup data retention capability at 2V. The industrial temperature range for this product is -40¬8C to +85¬8C, making it suitable for various applications.
