Intel D27128A - UV EPROM

The Intel D27128A is a 128 Kbit Ultraviolet Erasable Programmable Read-Only Memory (UV EPROM) chip. It is designed to store firmware or configuration data in embedded systems, featuring a quartz window that allows the memory to be erased via UV light exposure.

This component is commonly used in retro-computing projects, legacy microcontroller programming, or prototyping circuits that require reprogrammable non-volatile memory.
