The ISSI IS61WV25616BLL-10TLI is a 4Mb high-speed asynchronous CMOS static RAM organised as 256K words by 16 bits, with an 18-bit address bus and a 16-bit data bus. It has a 10ns access time, is rated to 100M Hz, and draws a nominal 45mA of supply current from a 3.3V rail with a 2.4V to 3.6V operating range. The IS61WV25616BLL-10TLI uses a single-port parallel interface and comes in a 44-pin surface-mount TSOP measuring 18.54mm by 10.29mm with a 1.05mm height. The industrial temperature grade covers -40 to 85 degrees C, and the part is lead free and RoHS compliant.

Asynchronous SRAM is used where a processor or FPGA needs immediately addressable scratchpad memory with no refresh controller and no initialisation latency, and the IS61WV25616BLL-10TLI serves that role as a 10ns buffer or working-memory device on a parallel bus. Common applications include networking and telecom line cards, industrial controllers, medical instrumentation, test equipment and automotive subsystems that buffer sampled data between acquisition and processing. Its low-power BLL grade and 2.4V to 3.6V range suit battery-backed configurations where the memory must retain contents on a standby rail. Buyers are typically embedded and industrial OEMs, often sourcing it as a drop-in for a legacy 256K by 16 SRAM footprint on a long-lifecycle board.
