Abstract
A novel RTC module consisting of an ASIC assembled in a miniature ceramic package together with a 32 kHz XTAL has been developed. It operates from 1.5 to 5 V, consumes less than 250 nA and is capable of generating a temperature compensated 1 PPS signal with a stability of ±3 ppm over the -40 to 85°C range. Designed for consumer applications, the microsystem is now in production at the market introduction phase.
