Product Overview

Intel D2732 is a 32-kilobit ultraviolet-erasable programmable read-only memory organized as 4,096 words by 8 bits. Housed in a 24-pin ceramic dual in-line package (Cerdip), it features a quartz window for UV erasure. The 2732 series was widely used in late-1970s and 1980s microcomputers, arcade systems, and industrial controllers for firmware storage.

This device operates from a +5V supply during read operations. Programming requires a compatible EPROM programmer and the correct programming voltage for the specific D2732 revision. The memory must be erased with ultraviolet light before reprogramming.
