DS1643-100+. Overview
This real time analog clock can be found in package DIP.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 5V which is provided to it.The RTCs are equipped with 28 pins.Timer or RTC is the subcategory in which the RTCs belongs.The RTC times embed a memory of 8kB available for storing programs and data.The frequency of real time clocks' output should not be higher than 0.032MHz.In order for it to be powered, it requires a power supply of 5V.28 pins are attached to it.Upon receiving an input signal, 1 timers output a signal at a preset time.It reaches a maximum supply voltage of 5.5V (Vsup).This electrical real time analog clock has the TIMER, REAL TIME CLOCK type of uPs/uCs/Peripheral ICs.In order to maintain normal operation, the supply voltage (Vsup) must be kept above 4.5V.A minimum operating temperature of 70°C should be maintained.
