Development Kit: CPLD XC-9572
Developed at R.K.N. ENGG. COLLEGE (P.C.B Lab.), NAGPUR
Guided by: Dr. S.S. Limaye( Principal R.K.N. ENGG. COLLEGE)
The development kit for Xilinx CPLD XC-9572 PC84 is an in-system programmable kit that includes on-board input/output interfaces. The kit consists of two parts. The first is the buffer circuit that is used to connect the kit to the parallel port of the computer which is used to transfer the file from the computer to the CPLD chip. The second part is the training kit features. The kit is completely designed in OrCAD. The kit is developed using surface mount technology and hence the size of the kit has considerably reduced.
The programming circuit is placed on the same PCB as that of the training kit and hence the kit is in-system programmable. This circuit is basically provided by the Xilinx and is available on the Xilinx website. The belo diagram shows the circuit for the programming cable:

The interfaces included on the kit are:
Inputs:
- Switches (Input Keys)
- ADC 0809
- Clock
Outputs:
- ULN driver
- LED’s
- Seven-segment displays in Multiplexed mode
- Transceiver MAX 232 for UART implementation
- DS 1307 Real Time Clock
