Nxp (PCF8523T/1,118) Calendar, Clock IC, I2C, 1.2 V to 5.5 V supply, SOIC-8

Calendar, Clock IC, Format (YYYY:MM:WK:DD:hh:mm:ss/Binary), I2C, 1.2 V to 5.5 Vsupply, SOIC-8Product OverviewThe PCF8523T/1,118 is a Real-Time Clock and calendar optimized for low powerconsumption. Data is transferred serially via the I²C-bus with a maximum datarate of 1000kbps. Alarm and timer functions are available with the possibilityto generate a wake-up signal on an interrupt pin. An offset register allowsfine-tuning of the clock. This has a backup battery switch-over circuit, whichdetects power failures and automatically switches to the battery supply when apower failure occurs.Battery backup input pin and switch-over circuitFreely programmable timer and alarm with interrupt capabilityInternal power-on resetOpen-drain interrupt or clock output pinsProgrammable offset register for frequency adjustmentApplicationsClock & Timing, MeteringProduct InformationDate Format: YYYY:MM:WK:DD:Hr:Min:SecsClock Format: BinaryClock IC Type: Calendar, ClockSupply Voltage Min: 1.2VSupply Voltage Max: 5.5VClock IC Case Style: SOICNo. of Pins: 8PinsIC Interface Type: I2COperating Temperature Min: -40°COperating Temperature Max: 85°C
