Intel LD27256-25 is a 256Kbit CMOS UV EPROM organized as 32K words by 8 bits. Featuring a maximum access time of 250ns, this device operates asynchronously and utilizes a parallel interface with 3-state outputs. The component is housed in a 28-lead Ceramic Dual In-line Package (CDIP) with a window for UV erasure. It operates over a temperature range of -40°C to 85°C with supply voltages between 4.75V and 5.25V. The LD27256 series finds application in industrial control systems, telecommunications infrastructure, and legacy computing systems requiring reliable non-volatile program storage.
