MC146818 - REAL-TIME CLOCK PLUS RAM

Motorola

Datasheet Details

a complete time-of-day clock with alarm and one hundred year calendar, a programmable periodic inter- rupt and square-wave generator, and 50 bytes of low-power static RAM. The MC146818 uses high-speed CMOS technology to interface I with 1 MHz processor buses, while consuming very little power. The Real-Time Clock plus RAM has two distinct uses. First, it is designed as a battery powered CMOS part (in an otherwise.
