The Application of ISP Technology in the Hardware Design

ISP technology is advanced in CMOS PLD field.ISP devices can finish most of system performances.All devices can be programmed with a simple daisy chain.The fuse file is written into ISP device with a download cable.In the circumstance of studying the principle of ISP PLD technique and VHDL and handling PLD developing tools which include WVOffice and ispDS+ 5.0,we apply the technique to design MCU with VHDL.The PCB circuit with PROTEL in accordance with locking pins of device is made and debugging MCU is finished.
