The MCP79411T-I/SN is a battery-backed I²C real-time clock/calendar that features a range of timekeeping capabilities, including tracking hours, minutes, seconds, day of the week, day, month, and year, with leap year compensation until the year 2399. It supports both 12-hour and 24-hour formats and is optimized for use with 32.768 kHz crystals. The device includes on-chip digital trimming for frequency calibration with a resolution of ±1 ppm and a range of ±129 ppm. This part number includes 1 Kbit of EEPROM memory, which is software write-protectable, and 64 bytes of battery-backed SRAM. Additionally, it features a 64-bit protected EEPROM area for storing critical information, such as a unique MAC address. The MCP79411T-I/SN supports dual programmable alarms and has a versatile output pin that can be configured for clock output, alarm output, or as a general-purpose output. Operating voltage ranges from 1.8V to 5.5V, with a low timekeeping current of 1.2 µA at 3.3V and a backup current of 925 nA at 3.0V. The device is designed for industrial applications, with an operating temperature range of -40°C to +85°C. It is available in multiple package types, including 8-lead SOIC, MSOP, TSSOP, and 2x3 TDFN. The MCP79411T-I/SN is suitable for applications requiring precise timekeeping and low power consumption.
