The paper analyses the implementation properties of unit codes as an alternative to classical binary codes. The possibility of forming a logic-time code, which is a symbiosis of two known unit codes: unit normal and unit positional (marking) codes, is shown. This allows to provide an accelerated principle of recording information and lower energy consumption during its storage. Analytical expressions for calculating hardware and time costs for a specific implementation of unit data coding on a shift register and a binary counter with a decoder are presented. It is the absence of decoding of the generated data that requires a multiple increase in the number of connections in the circuits.  The widespread use of programmable logic ICs makes it possible to eliminate this problem by compactly placing devices with single coding in a FPGA chip. This makes it possible to use unit codes as an alternative to binary codes for data transmission, as well as in some types of control devices for encoding their states and in storage devices for addressing their contents. As an example, the efficiency of using unit codes for encoding the states of microprogrammable automata is shown, which is achieved by the relative simplicity of combination schemes and the absence of the need to decode code combinations of the automaton states
