Advanced Micro Devices AM27256-35-BUC is a 32,768 word by 8-bit (32K x 8) One-Time Programmable (OTP) Read-Only Memory (ROM) device. This MOS technology component offers a maximum access time of 350 nanoseconds and operates asynchronously. The memory organization is 32K words with an 8-bit data width, providing a total density of 262,144 bits. It features common I/O and 3-state output characteristics. The device is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) package, identified by the JEDEC code R-XQCC-N32. Operating over a temperature range of -55°C to +125°C, it requires a nominal supply voltage of 5V and has a typical supply current of 100mA. This component is utilized in applications such as industrial control systems and legacy equipment requiring non-volatile program storage.
