MCP7940MT-I/ST Product Details

MCP7940MT-I/ST Overview


There is an embedded version in the package 8-TSSOP (0.173, 4.40mm Width).Packaged as Tape & Reel (TR).This electrical RTC is powered by 1.8V~5.5V voltage.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).A temperature of -40°C~85°C should be used for operation.During operation, Alarm, Leap Year, Square Wave Output, SRAM can be guaranteed.The 8 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.It is possible to see 2.5V voltage being supplied to this RTC real time clock.8 pins are attached to it.RTCs are a member of the family MCP7940M.Its supply voltage is --.In these RTC times, there is a memory of 64B where data and programs can be stored.This RTC module has a mounting type of Surface Mount.A power supply of 2/5V is used to power it.8 pins are present on it.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.RTC time is important to maintain the supply voltage at 2.5, 3.3, 5 V in order to maintain high efficiency.Real-time clocks belonging to the -- series are this type.In this electrical real time analog clock, there is a uPs/uCs/Peripheral ICs type of TIMER, REAL TIME CLOCK.
