2.Description
The MCP7941X series of low-power Real-Time Clocks(RTC) uses digital timing compensation for an accurateclock/calendar, a programmable output control forversatility, a power sense circuit that automaticallyswitches to the backup supply, and nonvolatile memoryfor data storage. Using a low-cost 32.768 kHz crystal,it tracks time using several internal registers. Forcommunication, the MCP7941X uses the I2C™ bus.The clock/calendar automatically adjusts for monthswith fewer than 31 days, including corrections forleap years. The clock operates in either the 24-houror 12-hour format with an AM/PM indicator andsettable alarm(s) to the second, minute, hour, day ofthe week, date or month. Using the programmableCLKOUT, frequencies of 32.768, 8.192 and 4.096kHz and 1 Hz can be generated from the externalcrystal. Along with the on-board Serial EEPROM and battery-backed SRAM memory, a 64-bit protected space isavailable for a unique ID or MAC address to beprogrammed at the factory or by the end user.The device is fully accessible through the serialinterface while VCC is between 1.8V and 5.5V, but canoperate down to 1.3V for timekeeping and SRAMretention only. The RTC series of devices are available in the standard8-lead SOIC, TSSOP, MSOP and 2x3 TDFN packages
