This Application Note describes how to use the 87C751
microcontroller to implement a gang programmer for the Philips
PCF8582 and PCF8581 I2C EEPROMs. Included are software,
schematic, and PCB layout to allow copying from one 16-pin source
EEPROM into ten slave EEPROMs. When the process is
completed, a green LED turns on and a small buzzer sounds. A red
LED by each slave socket indicates a failed IC.
The PCF8582 is a 256×8 CMOS EEPROM with I2C interface. It
comes in a variety of 8- and 16-pin plastic packages. This particular
layout uses the 16-pin Dual In-Line package. The PCF8581 is a
128×8 CMOS EEPROM.
