PD28 Pin Routing


Instruction Sheet

Using The PD28 For 28(C)16 EEPROMS

The 28(C)16 in the 32 Pin PLCC package has the same I/O pinout as the memory devices supported by the PD28 adapter. The 28(C)16 has a 24 pin DIP equivalent, however. VCC from a programmer that supports the DIP device would not provide power to the appropriate PLCC pin with the use of the PD28 adapter as-is. This can be corrected by the use of a jumper between DIP Pin 28 of the adapter (upper right hand corner) and DIP Pin 26 (2 pins below). The jumper must be removed when using devices other than
the 28(C)16.
