The Microchip Technology MCP795B20-I-ST is a Real Time Clock (RTC) IC featuring a clock/calendar function with 64 bytes of integrated EEPROM. This device utilizes a serial peripheral interface (SPI) for communication. Designed for surface mount applications, it is housed in a 14-TSSOP package with a 0.173" (4.40mm) width. Key features include alarm functionality, leap year compensation, square wave output, SRAM, a unique ID, and a watchdog timer, all contributing to robust timekeeping. The operating temperature range is -40°C to 85°C, with a supply voltage range of 1.8V to 5.5V and a battery supply range of 1.3V to 5.5V. The current draw for timekeeping is a maximum of 1µA at 1.8V. This component is suitable for applications requiring accurate timekeeping and data logging, such as industrial control, consumer electronics, and automotive systems. The date format is YY-MM-DD-dd, and the time format supports HH:MM:SS:hh with 12 or 24-hour options.
