FACT SHEET | RV-8803-C7 Subject to change without notice Version 1.0, 29-April-16 Copyright © 2016, EM Microelectronic-Marin SA www.emmicroelectronic.com Real Time Clock Module with I2C-Bus General Description Features The RV-8803-C7 is a 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 across 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 or reel with 3’000 parts.
