The MCP79412T-I/ST is a Real Time Clock (RTC) integrated circuit developed by Microchip Technology. This RTC IC features a clock/calendar function with a memory capacity of 64 bytes and an additional 1 kilobit of EEPROM, interfacing via an I2C 2-wire serial protocol. Encased in an 8-TSSOP package with a width of 4.40mm, the device operates efficiently with a current consumption of 1.2µA at 3.3V. It provides reliable performance over a voltage range of 1.8V to 5.5V, and supports date formats including year-month-day-day of the week (YY-MM-DD-dd), which ensures precise timekeeping functions in a compact and efficient form factor.
