ISL1208IB8-TK Overview
In the SOIC package, real time clocks is embedded as a dependency.When a transmission line is terminated with 8 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It should be noted that this RTC real time clock is being supplied with 3V voltage at the moment.A total of 8 pins are equipped with the RTCs.RTC times embed a memory of 2B for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.Mounting type Surface Mount is chosen for the RTC module.In order for it to be powered, it requires a power supply of 3/5V.When an input signal is received, 1 timers are used to output a signal at a preset time.A temperature higher than -40°C is ideal for operating.RTC time is recommended to keep the operating temperature below 85°C.It reaches a maximum supply voltage of 5.5V (Vsup).In this electrical real time analog clock, uPs/uCs/peripheral ICs are of the type TIMER, REAL TIME CLOCK.In order to maintain normal operation, the supply voltage (Vsup) must be kept above 2.7V.
