The Advanced Micro Devices AM27C256-55JC is a 32K x 8 bit One-Time Programmable (OTP) Read-Only Memory (ROM) device. Featuring CMOS technology, this component offers a maximum access time of 55ns, ensuring efficient data retrieval. The memory organization of 32K words by 8 bits provides a total density of 262,144 bits. This device operates asynchronously with common I/O and 3-state output characteristics, supporting a supply voltage range of 4.5V to 5.5V. Packaged in a 32-terminal Ceramic Quad Flatpack (PQCC32) with J-bend terminals designed for surface mounting, it operates within a commercial temperature range of 0°C to 70°C. Applications for this type of ROM include industrial control systems, consumer electronics, and legacy system designs requiring non-volatile program storage.
