The 70261L15PF is a high-speed 16K x 16 dual-ported static RAM designed for asynchronous access. It features true dual-ported memory cells, allowing simultaneous access to the same memory location from both ports. The device operates with a maximum access time of 15 ns for commercial applications and 20 ns for industrial applications, making it suitable for high-performance systems. Power consumption is low, with typical active power at 750 mW and standby power at 1 mW. The memory supports separate upper-byte and lower-byte control, enhancing compatibility with multiplexed bus systems. It includes on-chip hardware support for semaphore signaling and features built-in port arbitration logic. The 70261L15PF is packaged in a 100-pin Thin Quad Flatpack (TQFP) and operates on a single 5V power supply. It is available in both commercial and industrial temperature ranges, with the industrial version rated from -40°C to +85°C. This product is suitable for applications requiring efficient dual-port memory solutions.
