The MCP7940MT-I/MNY is a low-cost real-time clock/calendar (RTCC) designed for applications requiring accurate timekeeping. It features a comprehensive timekeeping capability, tracking hours, minutes, seconds, day of the week, day, month, and year, with leap year compensation up to the year 2399. The device operates with a 32.768 kHz crystal oscillator optimized for 6-9 pF load capacitance and includes on-chip digital trimming for frequency calibration with a resolution of ¬±1 PPM. This RTCC supports dual programmable alarms and offers a versatile output pin that can be configured for clock output, alarm signaling, or as a general-purpose output. The MCP7940MT-I/MNY operates over a wide voltage range of 1.8V to 5.5V, with a low typical timekeeping current of 1.2 OºA at 3.3V, making it suitable for low-power applications. It communicates via a 2-wire I¬=C interface with a clock rate of up to 400 kHz and is rated for industrial temperature ranges from -40¬8C to +85¬8C. The device is available in multiple package types, including 8-lead TDFN, making it adaptable for various design requirements.
