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 V supply, SOIC-8 Product Overview The PCF8523T/1,118 is a Real-Time Clock and calendar optimized for low power consumption. Data is transferred serially via the I²C-bus with a maximum data rate of 1000kbps. Alarm and timer functions are available with the possibility to generate a wake-up signal on an interrupt pin. An offset register allows fine-tuning of the clock. This has a backup battery switch-over circuit, which detects power failures and automatically switches to the battery supply when a power failure occurs. Battery backup input pin and switch-over circuit Freely programmable timer and alarm with interrupt capability Internal power-on reset Open-drain interrupt or clock output pins Programmable offset register for frequency adjustment Applications Clock & Timing, Metering Product Information Date Format: YYYY:MM:WK:DD:Hr:Min:Secs Clock Format: Binary Clock IC Type: Calendar, Clock Supply Voltage Min: 1.2V Supply Voltage Max: 5.5V Clock IC Case Style: SOIC No. of Pins: 8Pins IC Interface Type: I2C Operating Temperature Min: -40°C Operating Temperature Max: 85°C
