Optional - Please specify required code(s) when ordering High accuracy, ultra low power Ordering Information Built-in crystal for adjustment-free operation Time stamp event input function Product code ie: RV8803C7 Option code X (eg RV8803C7/X) denotes a custom spec. I2C-Bus interface (up to 400kHz) Programmable alarm, timer and interrupt Block Diagram Available on T&R - 1k or 3k pcs per reel. Evaluation / development board & manual available on request The I2C-Bus is a trademark of Philips Electronics NV Description The RV8803C7 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 giving 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 functions 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 sized and consumes the lowest current of all temperature compensated RTC modules.
