Simple EEPROM Programmer

An extremely popular programmer for the PIC16C84 microcontroller has already appeared in Elektor Electronics (Summer Circuits, 1998): that design used the parallel interface and the popular PIP-02 shareware from Silicon Studio, together with a special driver written by Dave Tait. PIP-02 is capable of programming not just PICs but also EEPROMs equipped with an I2C interface.This works with essentially the same hardware as we presented then, and the circuit in Figure 1 shows how the device to be programmed can be connected. The connection for the special programming voltage has gone, since the EEPROM does not require it.
