TC8250P

The TC8250P is a single chip CMOS LSI for real time clock which is composed as a peripheral LSI of a microcomputer.The RTC has a 32768 Hz X'tal oscillation circuit, counter group for clocking, control circuit for read/write from CPU and battery backup terminal.The package is a 16 pin DIP and a non-power interru-ption type clock system can be realized with I/O ports, X'tal and battery.

Features of the TC8250P are:(1)low power consumption;(2)32,768 Hz X'tal oscillation circuit;(3)counts seconds, minutes and hours;(4)counts days of the week, date, month, and year;(5)automatic leap year compensation;(6)battery back-up function with low voltage detector;(7)battery charge control terminal;(8)write protect key for sure operation.

The absolute maximum ratings of the TC8250P can be summarized as:(1)supply voltage:-0.5 to +7.0 V;(2)input voltage:Vss-0.5 to Vdd+0.5 V;(3)operating temperature:-40 to +85;(4)storage temperature:-65 to +125.If you want to know more information such as the electrical characteristics about the TC8250P,please download the datasheet in www.seekic.com or www.chinaicmart.com .
