This Intel D27256 is a 32K x 8 UV Erasable Programmable Read-Only Memory (UVPROM) featuring a 250ns maximum access time. Fabricated using MOS technology, this component offers a 262,144-bit density and operates asynchronously. The D27256 employs a parallel interface with 3-state outputs for flexible system integration. It comes in a 28-pin Ceramic Dual In-line Package (CDIP28) with through-hole mounting terminals spaced at 2.54mm. Typical applications include embedded systems, industrial control, and legacy system upgrades where non-volatile program storage is required. The device operates within a 0°C to 70°C temperature range and requires a 5V nominal supply voltage.
