The 71342SA20PF8 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 at 700mW and standby power at 1mW. The memory supports semaphore signaling between ports, enhancing coordination in multi-port access scenarios. It is TTL-compatible and operates on a single 5V power supply, with an industrial temperature range of -40¬8C to +85¬8C available for selected speeds. The device is offered in plastic packages, specifically a 64-pin TQFP or a 52-pin PLCC. Battery backup operation is supported for the low-power version, allowing data retention at 2V.
