Below is the project statement :
Design a microprocessor based EPROM programmer to program 2716.The EPROM can be programmed by applying 25V at VPP and 5V at OE pin. Initially all data of EPROM will be 1's and the user should make the bits zero selectively. The bit parallel data is applied to the data output pins (D0-D7). The address for the EPROM is provided through the address pins. To program the address of each location to be programmed should be stable for 55ms.When address and data are stable, a 50ms active high pulse is applied to CE input.
