The Advanced Micro Devices AM27256-1LC is a 32K x 8 bit (262,144 bit) NMOS technology One-Time Programmable (OTP) ROM. This component features an asynchronous operating mode with an access time of 170ns. The memory organization is 32K words by 8 bits, providing a parallel data interface. Designed for surface mounting, it is housed in a 32-terminal Ceramic Chip Carrier (CQCC32) package with a JEDEC code R-CQCC-N32. The device operates from a supply voltage range of 4.75V to 5.25V, with a nominal voltage of 5V, and exhibits a maximum supply current of 100mA. Its output characteristics are 3-state. Typical applications for this component include industrial control systems, telecommunications infrastructure, and legacy system designs requiring non-volatile program storage.
