Haruchika HP-043 Control Board Replica

Control board replica of the obsolete and not supported by the manufacturer Haruchika Lens Processing machine HP-043.

The replica is designed in SMT with an Xilinx CoolRunner-II CPLD XC2C64A, allowing to reprogram anytime instead of the original control board that is discrete, THT + hardwired.

Key Features

• Design based on the Xilinx XC2C64A CoolRunner-II CPLD.
• All inputs with 5V noise immunity, 1V hysteresis and double capacitor filtering, using the Low Power Low Offset Voltage Quad Comparators National Semiconductors LM2901.
• The outputs we improved using the latest BDX53B Darlington Power Transistors from ON Semiconductor.
