Cardinal Intros Four-Part Series of Real Time Clocks
New real-time clock oscillators.
Wayne, NJ — Cardinal Components, Inc. has introduced a four-part series of Real Time Clocks (RTCs) numbered CS-1302, 1307, and CT-1380, along with series C-8563, all based on the company's 32.768kHz quartz crystal.
The CS-1302 permits 2.0V to 5.5V operation, has 31 x 8 RAM for scratch-pad data storage, and uses less than 300nA at 2.0V. It provides year, with leap-year compensation, month, day of the week, hours, minutes, and seconds. Offered in 8-pin SOP and 8-pin DIP, the CS-1302 series is suitable for instrumentation, medical applications, time recorders, security access and control, door controls, flow meters, and mobile telephones.
The new CS-1307 RTC is equally versatile. It has a battery backup mode, I
C interface, 56 bytes of scratch-pad NVSRAM for data storage, and programmable clock output. Applications include time records, security access, door control, flow meters, and mobile telephones.
The new CT-1380 RTC offers 2.0V to 5.5V full operation, simple serial 3-wire interface, TTL compatibility, and less than 400 nA @ 2.0 volts. The C-8563 RTC permits 1.8V to 5.0V operation and offers I
C bus, alarm, and timer functions.
It has a programmable clock output (32.768kHz, 1024Hz, 32Hz and 1Hz) and, like the others in the series, provides year, month, day, day of the week, hours, minutes, and seconds with century flag and incorporates alarm and timer functions and a built in power-voltage detecting circuit. The C-8563 is low power, making it useful in applications that include industrial, instrumentation, medical, security, timer recorders, and water and gas flow meters.
