00 Nov 2003 The ICM7170 real time clock is a microprocessor bus compatible peripheral, fabricated using Intersil’s silicon gate CMOS LSl process.
An 8-bit bidirectional bus is used for the data I/O circuitry.
The clock is set or read by accessing the 8 internal separately addressable and programmable counters from 1/100 seconds to years.
The counters are controlled by a pulse train divided down from a crystal oscillator circuit, and the frequency of the crystal is selectable with the on-chip command registe...
