DS1689SN+ Product Details
DS1689SN+ Overview
28-SOIC (0.295, 7.50mm Width) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.7V~3.3V 4.5V~5.5V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Surface Mount.Electronic time clocks should be -40°C~85°C degrees Celsius during operation.Electronic time clocks are possible to guarantee NVSRAM when operating.Transmission lines can be terminated with 28 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 3V supplied to it.28 pins are present on it.DS1689 are RTC s family.2.5V~3.7V is the supply voltage of this electrical digital time clock.A memory of 114B is embedded into the RTC times for storing programs and data.A frequency of 0.032MHz should not be exceeded by real time clocks' output.The power supply is 3/5V.1 timers are in the real time clock that outputs a signal in response to an input signal.In addition, it is characterized by CAN ALSO OPERATE WITH 5V SUPPLY.16 Bits are used in the design of this digital time clock.
