A digital clock is a type of electronic clock that displays the time digitally. This clock is more reliable, accurate, maintenance free and portable than mechanical clock. Usually, digital clocks are associated with electronic devices and widely used in everyday of human life. Although there are many digital clocks with 7-segment digits, a clock that displays Myanmar digits is very rarely. This paper deals with circuit implementation of a digital clock that allows displaying Myanmar digits. In this work a circuit of Myanmar-digit decoder is proposed. A control scheme is designed to display Myanmar digits on 8*8-LED matrix. Schemes of 0-5, 0-9 and 0-23 up-counters are synthesized for counting the time of the clock. Using the combination of the considered devices, a digital clock with Myanmar digits is developed and its circuit is modeled in Altera Quartus-II environment. The reliability of the result of the developed digital clock is practically confirmed by using Altera DE-1 board and 8*8-LED matrixes (1588BS).
