Advanced Micro Devices AM27C256 UVPROM, a 32K x 8 CMOS device, offers a maximum access time of 150ns. This component, identified by part number AM27C256-150DCB, features a 262144-bit memory density organized into 32,768 words by 8 bits. Operating in asynchronous mode with 3-state outputs, it requires a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V. The AM27C256-150DCB is housed in a 28-lead ceramic dual in-line package (CDIP28) with through-hole terminals, suitable for industrial and commercial applications requiring reliable non-volatile storage. Its standby current is rated at a maximum of 100µA, and the typical supply current is 25mA. The operating temperature range is 0°C to 70°C. This UV-erasable programmable read-only memory is commonly found in legacy systems, industrial control, and embedded applications where firmware storage is critical.
