It integrates the crystal (XTAL) directly into a hermetically sealed ceramic package, removing the need for external clock tuning.With a maximum timekeeping current of just 0.08µA (80nA), it is well suited to long-life designs where every nanoamp matters. Communication is via a standard I2C, 2-wire serial interface for straightforward integration with microcontrollers.The module also includes useful internal functions such as a backup battery trickle charger, watchdog timer and 256 bytes of user RAM, making it a compact timing solution for embedded and remote applications.Features:Alarm: IncludedProgrammable Clock Output: IncludedRAM: IncludedTimer: IncludedTrickle Charger: IncludedWatchdog Timer: IncludedSpecifications:Type: Clock/CalendarFeatures: Alarm, Programmable Clock Output, RAM, Timer, Trickle Charger, Watchdog TimerMemory Size: 256BTime Format: HH:MM:SS:hh (12/24 hr)Date Format: YY-MM-DD-ddInterface: I2C, 2-Wire SerialVoltage - Supply: 1.5V ~ 3.6VCurrent - Timekeeping (Max): 0.08µA @ 3VOperating Temperature: -40°C ~ 85°C (TA)Mounting Type: Surface MountMfg #: RV-1805-C3-32.768KHZ-2PPM-TA-QC","vendor":"SparkFun","product_type":"Real Time Clock Module","in_stock":true,"options":[],"variants":[{"id":16071,"title":"Default Title","sku":"SF-COM-30227","mpn":"COM-30227","price":10.8,"on_sale":false,"in_stock":true,"available_quantity":16}]}
