Background. Sensors of various physical quantities, the information about the measured parameter in which is contained in the frequency of the output signal, are widely used in the on-board equipment of autonomous information and measurement systems (AIS). Sensor signal processing is carried out according to a given algorithm, which provides for the execution of various mathematical operations, one of which is frequency division. The hardware implementation of this operation can be performed on several cases of integrated circuits of standard logic. Reducing these hardware costs is an urgent task aimed at reducing the overall dimensions of AIIS electronic units and increasing their reliability. Materials and methods. One of the ways to solve this problem is the use of a specialized chip for time-pulse and digital-frequency conversion of 512PS8ВК. Results. The construction of digital frequency dividers on a 512PS8VC chip is considered. Expressions for frequency division coefficients are given. Conclusion. The 512PS8ВК chip can be used to build frequency dividers with fixed, programmable and variable integer and fractional division coefficients with values from 4 to 224.
