The Advanced Micro Devices AM27256-45LEB is a 32K x 8 bit One-Time Programmable (OTP) Read-Only Memory (ROM) device. Featuring NMOS technology, this component offers an asynchronous operating mode with a maximum access time of 450ns. The memory organization provides 32,768 words, each 8 bits wide, for a total memory density of 262,144 bits. This device operates with a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V, and a maximum supply current of 100mA. The AM27256-45LEB is housed in a 32-terminal Ceramic Quad Flatpack (CQFP) package, designated R-CQCC-N32. Its operating temperature range spans from -55°C to +125°C, making it suitable for demanding industrial and military applications. The common I/O type and 3-state output characteristics facilitate integration into various system designs. This component is commonly found in applications requiring fixed program storage, such as embedded systems, control systems, and legacy hardware.
