Abstract: Nowadays Erasable Programmable Read Only Memory (EPROM) is widely used in various instruments and devices for storing experimental or ordinary data, assembly code etc. This memory chip has large application in any industry or institute. EPROM programmer is needed in various sections of microprocessor based control system such as city traffic light control, temperature control, DC motor control, stepper motor control, robot control, various toy etc. The EPROM chip is also needed in computer hardware like motherboard, processor, printer, scanner etc. It is used in all of the above applications to read or write programming code sequence or data or various forms of sound and music. Bearing this in mind, a parallel port EPROM programmer is developed that can be used to write data to and read data from EPROM. A software has been developed to read, write, verify and reset of EPROM�s and controlling of the device. The developed hardware-software co-method for EPROM programmer is capable of programming those EPROM chips whose address buses are in the range of nine to sixteen bits and data buses are 8 bits. If the address buses and data buses of EPROM chips are not in the range mentioned above, then it is needed to set extra latches in the circuit and accordingly control words are generated. As the EPROM programmer is software based so it is user friendly and low cost compare to commercial one.
