产品概述
The RV-4162-C7-TA-QC-020 is an ultra low power C Real-time Clock Module with I²C bus. This ultra small RTC module has been specially designed for miniature and cost sensitive high volume applications. The very small SMT ceramic package combines the 32.768kHz crystal unit with the CMOS-based oscillator and real-time-clock circuitry. The clock function provides tenths/hundredths of seconds, seconds, minutes and hours. The calendar function tracks date, month, year and century with automatic leap year compensation. Programmable CLKOUT frequencies, alarm settings and watchdog function increase flexibility using this device.
