EBC Model PD28
Information Page
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.
DEVICE SUPPORT This adapter is designed to support 32 pin PLCC devices with a 28 pin DIP equivalent. Commonest uses would be 27(c)64/128/256/512 EPROMS and FLASH replacement devices. Consult the programmer manufacturer or contact EBC Company if in doubt about the use of this adapter for your application.
