Assuming this thing was designed in early 80's (which it probably was given the LQ470-like DIL 7segment LED displays) there certainly was soviet made NMOS ASIC that implemented most of the functionality in single package. But similarly to contemporary western counterparts it required bunch of funky supply voltages (albeit the supply rails used by soviet alarm clock ASICs are nowhere near the supply funkiness of Sanyo's essentially AC powered alarm clock ASICs) and were nowhere reliable enough to be used in space.
