Advanced Micro Devices AM21L49 series asynchronous SRAM, part number AM21L49-55LC, offers a 4Kb memory density organized as 1K words by 4 bits. This standard SRAM features a maximum access time of 55ns and operates with a supply voltage range of 4.5V to 5.5V, nominal 5V. The NMOS technology and 3-state output characteristics are suitable for applications requiring robust memory solutions. This component is housed in an 18-terminal Ceramic Quad Flat Pack (CQFP) package with a rectangular shape and surface-mount capability. Its specifications make it a viable option for industrial control, telecommunications infrastructure, and legacy system designs. The common I/O type and parallel interface facilitate integration into various system architectures.
