Intel H1702A

A 2048-bit EPROM (Erasable Programmable Read Only Memory). The 1702 was Intel's first official EPROM.

The 1702A is a 256 word by 8-bit electrically programmable ROM ideally suited for uses where fast turn-around and pattern experimentation are important. Initially all 2048 bits of the 1702A are in “0” state (output low). Information is introduced by selectively programming “1”s (output high) in the proper bit location. The 1702A is packaged in a 24 pin dual in-line package with a transparent lid. The transparent lid allows the user to expose the 1702A to ultraviolet light to erase the bit pattern. A new pattern can then be written into the device.

The circuitry of the 1702A is completely static. No clocks are required. Access times from 650ns to 1.5µs are available. The 1702A is fabricated with silicon gate technology. This low threshold technology allows the design and production of higher performance MOS circuits and provides a higher functional density on a monolithic chip than conventional MOS technologies.
