The intel 27256 is a 5v only, 262,144bit ultraviolet erasable cerdipplastic production p27256 electrically. Powerconnect 2716, powerconnect 2724, powerconnect 2748. An eprom rarely erom, or erasable programmable readonly memory, is a type of programmable readonly memory prom chip that retains its data when its power supply is switched off. If you do it this way, the programmer has to store all data in memory and then start programming during 8 minutes. A programmed eprom retains its data for a minimum of ten to twenty years, 5 with many still retaining data after 35 or more years, and can be read an unlimited number of times without affecting the lifetime. Data stored in rom cannot be electronically modified after the manufacture of the memory device. Find the pdf datasheet, specifications and distributor information.

And i have a 3 2708 from intel i am looking for 1 ou 2 2704 but all datasheet on the. Same requirements as example 2, but the eprom is now to be updated. The fact that the d2 kit has two eprom sockets available for 2708s makes this a. Intel mc2708 is supported by elnec device programmers. Wondering about the intel 2704 as it is a 4096bit 512x8 eprom and has the. Pin equivalent to the same requirements as example 2, but the eprom is now to be updated. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called nonvolatile. This parameter is guaranteed by device characterization, but is not production tested. Readonly memory rom is a type of nonvolatile memory used in computers and other electronic devices. So, the pin 22, that in the 2708 is the 9th address line, in the 2704 is a ground.
