The Advanced Micro Devices AM27S191A-BUA is a 4 Megabit (512K x 8) bipolar asynchronous Flash memory device. Featuring a maximum access time of 150ns, this component is designed for high-speed operation. The AM27S191 device family utilizes a parallel interface with 3-state outputs. This specific part is housed in a 32-terminal CQCC (Ceramic Quad Flatpak) package, identified by the R-CQCC-N32 standard. It operates over a wide temperature range of -55°C to +125°C, with a nominal supply voltage of 5V, ranging from 4.5V to 5.5V. The AM27S191A-BUA is suitable for applications in aerospace, defense, and high-reliability industrial systems requiring robust memory solutions. Its construction and screening levels, including 38535Q/M, 38534H, and 883B, are indicative of its suitability for demanding environments.
