10 pcs : PCF85063AT/AY - Real Time Clock Low Power Real time clocks

PCF85063 CMOS Real-Time Clock (RTC) & Calendar NXP Semiconductors PCF85063 CMOS Real-Time Clock (RTC) and Calendar offers precise timing in a small, low-power format and is well suited for a wide range of applications. The PCF85063 can be used to perform the standard functions of a real-time clock (RTC), tracking the actual time and date or acting as a reference timer. To support power management, the PCF85063 can be used to wake the microcontroller from hibernation mode, and in systems that use a PLL, it can serve as a system reference clock for the PLL input. The PCF85063 can also be used as a Watchdog or countdown timer, or as an activation timer to start measurements or initiate other functions.
