IS61WV25616BLL-10TL is an asynchronous static random access memory (SRAM) chip designed and manufactured by Integrated Silicon Solution, Inc. (ISSI). It has a capacity of 4MB and provides 256K words of memory, each word being 16-bits wide. It has an access speed of 10ns, and operates on a voltage of 3.3V. It is a low power device, allowing operation at reduced current levels when needed. The chip has an asynchronous design, meaning that operations can be performed with no delay between them. It is suitable for use in applications such as gaming consoles, industrial controllers, instrumentation, and network systems.
