BQ4845S-A4NTR Overview
Real time clocks is embedded in the 28-SOIC (0.295, 7.50mm Width) package.Time clock is packaged in the way of Tape & Reel (TR).The supply voltage of this electrical RTC is 4.75V~5.5V.The type of this electrical real time clock is Clock/Calendar.This real time clock (RTC) is mounted in the way of Surface Mount.The operating temperature should be -40°C~85°C.Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer can be ensured when operating.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.The supply voltage of this RTC real time clock is 5V.It is equipped with 28 pins.RTCs belongs to BQ4845 family.The supply voltage of this electrical digital time clock is 2.3V~4V.Real time clocks' output frequency should not exceed 0.032MHz.It is mounted in the way of Surface Mount.It operates from 5V power supplies.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.The supply voltage should be maintained at 5V for high efficiency.
