A digital core was designed and successfully tested to communicate with RFID-enabled devices. This digital core comprises of a communication block and a control block. The communication block is made up of two blocks, namely, the receiver block and the transmitter block whereas the control block controls the operation of the digital core. VHDL (Very High Speed IC Hardware Description Language) was used to design the digital block according to the ISO15693 standard specified for RFID-enabled devices. The developed VHDL code was successfully simulated and the design was transferred onto a CPLD. A test circuit was developed on a bread board with the CPLD and a commercially available RFID reader was used to successfully communicate with the designed digital core. Then a printed circuit board (PCB) was designed to validate the above design with all components including the CPLD for communication. This PCB meets all the specifications provided for communication by the ISO15693 standard. The developed digital core can be translated into a layout which can be part of an implantable or embedded RFID passive sensors chip.
