MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC68HC68T1/D MC68HC68T1 Real-Time Clock plus RAM with Serial Interface CMOS The MC68HC68T1 HCMOS Clock/RAM peripheral contains a real- time clock/calendar, a 32 x 8 static RAM, and a synchronous, serial, three- wire interface for munication with a microcontroller or processor. Operating in a burst mode, successive Clock/RAM locations can be read or written using only a single starting address. An on- chip oscillator allows acceptance of a selectable crystal frequency or the device can be programmed to accept a 50/60 Hz line input frequency. The LINE and system voltage (VSYS) pins give the MC68HC68T1 the capability for sensing...
