Ordering Information
Standard. Optional - Please specify required code(s) when ordering Specifications Available on T&R - 1k or 5k pcs per reel Evaluation / development board & manual a vailable on request The I2C-Bus is a trademark of Philips Electronics NV Block Diagram The RV3029C2 is a Real-Time-Clock Module with embedded crystal. This RTC has an I 2C Bus (2-wire Serial Interface) and offers temperature compensated time. The STC (Smart Temperature Compensation) can be factory calibrated to achieve a very high time-accuracy of ±6ppm from -40°C to +85°C (option A) and ± 8ppm from -40°C to +125°C (option C). Beside standard RTC functions, it includes a Backup-Battery Input with internal switchover function, a programmable trickle-charge circuitry, an integrated temperature sensor with digital output and offers 8 Bytes RAM and 2 Bytes EEPROM for customer application. The calendar function tracks year and leap-year flags. The clock tracks second, minute and hour in 24-hour format. Programmable alarm setting and universal timer functions increase flexibility.
