Multichannel Analyzer (MCA), is an instrument to record the nuclear radiation spectrum data. At first, MCA is built as a stand-alone instrument provided with graphical data display. The ability of the Personal Computer (PC) to analyze the data, high capacity data storage, data transfer and attractive visual data display could help to analyze the data of MCA better. These reason increase the need of PC integrated MCA. The MCA system can be built in a simple circuit, from some analogue and digital electronic components inside Programmable System on Chip (PSoC) Microcontroller. The purpose of this research is to build the system of PSoC-based MCA. To know the performance of the system, test of dead time of the system, the Integral Non-Linearity (INL) test and the Differential Non-Linearity (DNL) test had been taken. A software to analyze the radiation counting data has been built. The MCA system that had been built before consist of some circuits such as peak detector circuit, data conversion circuit, discriminator circuit and digital data transfer circuit. The result of the research showed the dead time of the system reached up to 2.573 x 10 -3 second. Based on the result, the INL and DNL value from the system respectively achieved at 1.62% and 57.49%. The linearity of the system was greatly affected by the peak detector circuit. By further developing the MCA system built before, the system of MCA is expected to meet the standard needed.
