Advanced Micro Devices AM27C256 UVPROM, part number AM27C256-95DIB, offers a 32K x 8 memory organization with a density of 262144 bits. This CMOS device features an asynchronous operating mode and a maximum access time of 90ns. The output characteristics are 3-state, facilitating bus contention management. Housed in a 28-terminal CDIP package (JESD30 code R-GDIP-T28), this component is designed for through-hole mounting. Operating over a temperature range of -40°C to 85°C, it requires a supply voltage of 5V (nominal) with a tolerance of 4.75V to 5.25V. Typical applications for this ultraviolet erasable programmable read-only memory include industrial control systems and legacy embedded designs where reliable non-volatile storage is critical. The package is ceramic and glass-sealed, with a terminal pitch of 2.54mm.
