Abstract
A timekeeping integrated circuit with devices partitioned into areas with different power supplies and level translators between the areas; the level translators use a memory cell for isolation and to shorten the signal active time for low power consumption. Also a one-wire communication port with low power input buffers may be used to detect very slowly varying voltages. The input buffers include staged decreasing resistors as a power dissipation limitation.
