Product Overview

Intel D2732-6 is a 32-kilobit ultraviolet-erasable programmable read-only memory (UVEPROM) organized as 4,096 words by 8 bits. The “-6” speed grade denotes a maximum access time of 650 nanoseconds. Housed in a 24-pin ceramic dual in-line package (Cerdip), this device features the characteristic quartz window used for UV erasure.

The 2732 family was widely used for firmware storage in early microcomputers, industrial controllers, arcade systems, and embedded designs. During read operation, the device runs from a single +5V supply. Programming requires an external EPROM programmer and elevated programming voltage per the Intel datasheet.

Frequently Asked Questions

Is the chip erased or programmed?

The programmed state is not verified. UVEPROM devices must be erased with ultraviolet light before reprogramming.

What does the “-6” suffix mean?

The “-6” indicates a 650 nanosecond maximum access time speed grade.

How is data erased?

Data is erased by exposing the quartz window to high-intensity ultraviolet light at the specified wavelength and duration per the manufacturer’s datasheet.

What voltage is required for operation?

During read operation, the device operates from a +5V supply. Programming requires an external EPROM programmer and the appropriate programming voltage defined in the Intel datasheet.

Can this replace other 2732 EPROMs?

It is compatible with systems designed for 2732-type 4K x 8 EPROMs, provided speed and programming voltage requirements match the original specification.
