EPROM adapter for ATMEL Programmer

Description: The EEprom programmer software supports the following devices 28C16, 28C256, 28C17, 29C256, 28C64. Diode D1 and resistor R1 provide the VDD isolation when programming the 24 pin devices. The jumper J3 must be shorted for 24 pin devices, and open circuit for 28 pin device programming. Following EEPROMs are pin compatible with their EPROMs version, 28C16 ---> 2716, 28C64 ---> 2764, 29C256 ---> 27256.

The EEprom programmer is designed to facilitate the programming of various EEPROM devices, specifically the 28C16, 28C256, 28C17, 29C256, and 28C64 models. The circuit employs a diode (D1) and a resistor (R1) to ensure proper VDD isolation during the programming process for 24-pin EEPROM devices. This isolation is critical to prevent unintended voltage levels from affecting the programming sequence and the integrity of the data being written to the EEPROM.

The configuration of jumper J3 is essential for the correct operation of the programmer. When programming 24-pin devices, J3 must be shorted to allow the necessary connections to be made. Conversely, for programming 28-pin devices, J3 should remain open, altering the circuit path to accommodate the different pin configurations of the EEPROMs.

The pin compatibility of the EEPROMs with their respective EPROM counterparts is an important feature of this programmer. The 28C16 EEPROM is pin compatible with the 2716 EPROM, the 28C64 with the 2764, and the 29C256 with the 27256. This compatibility allows for seamless integration and programming, ensuring that users can transition between EEPROM and EPROM technologies without the need for extensive modifications to the hardware setup.
