Real-time clock module RV-3032-C7

RV-3032-C7 is a High Performance Temperature Compensated Real-Time Clock Module with I²C interface which offers the world's best time accuracy across industrial temperature range at ultra-low current consumption. Factory calibrated temperature compensation of embedded 32.768 kHz crystal resonator provides ± 2.5 ppm accuracy from -40° to 85°C (±1.5 ppm 0° to 50°C; equivalent to ±0.13 sec/day). It allows extended battery life through timekeeping current as low as 160 nA. Beside standard Real-Time Clock (RTC) functions like Calendar (100th of second through (leap-) year), Timer & Alarm, it includes an accurate high-resolution Temperature Sensor with programmable temperature window detection interrupt, smart power management functions and User EEPROM & RAM. External event detection interrupt with time stamp combined with programmable password, offers security solutions against fraud and hacking. Ultra-small footprint and compact size with reliable vacuum-sealed metal lid provides all advantages of SMT fully integrated and easily implementable device for miniature and cost sensitive high volume applications. Automatic Backup Switchover with Interrupt Function Trickle Charger with versatile Charge Pump allowing: VBACK ≥ VDD Use of 1.75 V TDK CeraCharge™ Supply Voltage Drop Detection (1.2 V) with Interrupt Timestamped External Event Input Detection with Interrupt Programmable Password Protection against Hacking Configuration EEPROM 12-bit Temperature Sensor: Accuracy: ± 1°C typ. Resolution: (0.0625°C/step) Timestamped & Programmable Temperature Window Detection with Interrupt Internal Power-On Reset Periodic Countdown Timer Periodic Time Update (seconds, minutes)
