A design of embedded control circuit based on STM32 chip was introduced in the paper, which was adopted in a calibration simulation system of a 3mm waveband detector. The function of this control circuit, the selection and interface circuit of LCD and memory module circuit for the calibration simulation system database were discussed in detail. In addition, a database was set up and peripheral cir- cuit, such as a real time clock circuit, a humidity and temperature sensor circuit, PS/2 interface circuit for mouse and SDIO interface circuit, were presented. Experiment results demonstrated that the embedded control circuit could satisfy the requirement of 3ram waveband calibration simulation system, with simple operation, high control precision, stability and real--time.
