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 -40°C to +85°C.
Standard Clock & Calendar function tracks second, minute, hour in 24-
hour format, year and leap -year flags. 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” (178 mm) reel with 1'000 parts
7” (178 mm) reel with 3'000 parts
