Intel AD27C256-120V10 is a 256Kb CMOS UV Erasable Programmable Read-Only Memory (UVPROM) from the AD27C256 series. This component features a memory organization of 32K words by 8 bits, providing a total density of 262,144 bits. It operates asynchronously with a maximum access time of 120ns. The device is housed in a 28-lead Ceramic Dual-In-Line Package (CDIP) with a window for UV erasure, designed for through-hole mounting. The AD27C256-120V10 supports a supply voltage range of 4.5V to 5.5V with a nominal 5V operation. Typical applications include industrial control systems, legacy system upgrades, and embedded systems requiring non-volatile program storage where UV erasability is advantageous for prototyping or field updates. Standby current is rated at 100µA maximum, with an active supply current of 30mA maximum. Operating temperature is specified from -40°C to +125°C.
