Description
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 onchip command register. An extremely stable oscillator frequency is achieved through the use of an on-chip regulated power supply.
