dimensions RV-8803-C7 real time clock module with i 2 c-bus all dimensions in mm typical description: the RV-8803-C7 is an high accuracy, ultra low power real-time-clock module with embedded 32.768 khz crystal. high accuracy, high stability is achieved by factory calibrated, temperature compensated dtcxo and results to time-accuracy of 3.0 ppm accross the temperature range from -40c to +85c. standard clock & calendar function tracks second, minute, hour in 24- hour format, year and leap -year ags. beside standard rtc function like timer & alarm, it includes integrated temperature sensor, time stamp event input and user ram and offers i2c-bus (2-wire interface). RV-8803-C7 is the smallest and offers the lowest current consumption among all temperature compensated rtc modules. for pick-and-place equipment, the parts are available in 12 mm tape: 7?
