Advanced Micro Devices AM2149 series asynchronous SRAM, part number AM2149-55LMB, offers a 4096-bit memory density organized as 1K words by 4 bits. This MOS technology component features a maximum access time of 55ns and operates with a nominal supply voltage of 5V. The device is housed in an 18-terminal Ceramic Chip Carrier (CQCC18) package, suitable for surface mounting applications. Designed for robust operation across an extended temperature range of -55°C to +125°C, this component meets MIL-STD-883 Class B (Modified) screening standards. Its 3-state output characteristics and common I/O type make it well-suited for applications in aerospace, defense, and industrial control systems demanding high reliability.
