Advanced Micro Devices AM27256-4DE is a 32K x 8 UV Erasable Programmable Read-Only Memory (UVPROM) featuring NMOS technology. This component offers a maximum access time of 450ns and operates asynchronously. The organization of 32,768 words, each 8 bits wide, provides a total memory density of 262,144 bits. It is housed in a 28-lead Ceramic Dual In-line Package (CDIP) with a glass-sealed window for UV erasure. Operating across a temperature range of -55°C to +125°C, this parallel memory device requires a supply voltage of 5V (±5%). The AM27256-4DE is suitable for applications in industrial control, telecommunications, and legacy system design where robust, non-volatile program storage is critical. Its through-hole termination and 3-state output characteristics facilitate integration into existing board designs.
