The 71342LA45J8 is a high-speed 4K x 8 dual-port static RAM from Quarktwin Technology Ltd. It features asynchronous operation from both ports, allowing independent access for reads and writes. The device operates with a maximum access time of 20ns for commercial applications and 25ns for industrial applications. Power consumption is low, with typical active power usage of 700mW and standby power of 1mW. The memory supports battery backup operation with 2V data retention, making it suitable for applications requiring low power and data preservation. It is TTL-compatible and operates on a single 5V power supply. The device is available in plastic packages and supports an industrial temperature range of -40¬8C to +85¬8C for selected speeds. The built-in semaphore logic facilitates communication between the two ports, enhancing its utility in multi-processor systems.
