Original Electronic Real Time Clock PT7C43390LEX Clock Timer ICs Integrated Circuit
The PT7C43390 is a CMOS PC-bus real-time clock IC, whichoperates with the very low current consumption and in thewide range of operation voltage. The operation voltage is l.35V to 5.5 V so that the RTC can be used for various powersupplies from main supply to backup battery. In the systemwhich operates with a backup battery, the included freeregisters can be used as the function for user's backup memoryUsers always can take back the information in the registerswhich is stored before power-off the main power supply, afterthe voltage is restored.
The IC has the function to correct advance / delay of the clockdata speed, in the wide range, which is caused by theoscillation circuit's frequency deviation. Correcting accordingto the temperature change by combining this function and atemperature sensor, it is possible to make a high precise clockfunction which is not affected by the ambient temperature.
