The IS61LV25616AL-10TL is a 4Mbit (256K x 16-bit) high-speed low-power asynchronous SRAM from ISSI operating at 3.3V with 10 ns access time. It features upper\/lower byte control (LB#, UB#) and is packaged in a 44-pin TSOP II, making it ideal for high-performance cache and buffer applications.<\/p>\n

The fast 10ns access makes it ideal for cache and high-performance buffer applications. Upper\/lower byte control via LB# and UB# enables flexible 8-bit or 16-bit bus access. The 44-pin TSOP II package is widely supported in embedded and networking designs.","working_principle":"Fully static asynchronous SRAM with 10ns access time.
