The Advanced Micro Devices AM27C256 is a 256 kilobit, ultraviolet erasable, programmable read-only memory (UVPROM) organized as 32K words by 8 bits. This CMOS device offers a maximum access time of 250ns and operates from a single 5V supply (4.75V to 5.25V). Featuring 3-state outputs and a common I/O, the AM27C256 is suitable for applications requiring non-volatile code storage and data retention. Its robust ceramic, metal-sealed cofired CQCC32 package with a window for erasure ensures reliability in demanding environments. This component finds application in industrial control systems, telecommunications infrastructure, and legacy embedded systems where stable program storage is critical. The AM27C256 series utilizes advanced CMOS technology for low standby current (120µA max) and efficient operation.
