Product Description
Microchip MCP79401-I/SN is a highly integrated 64-bit real-time clock (RTC) designed for accurate timekeeping and calendar functions in electronic systems. It features a 2-wire I2C compatible interface and is housed in a compact 8-pin SOIC surface mount package, making it ideal for space-constrained applications.
This RTC supports date formats including day of week (DW), day:month:year (D:M:Y), and time format of HH:MM:SS, providing versatile use in a variety of clock and timing devices. It operates reliably within a wide temperature range from -40°C to 85°C, suitable for industrial and commercial environments.
The MCP79401-I/SN includes advanced features such as an automatic battery switchover circuit that enables backup power to the RTC, ensuring continual timekeeping during power failures. Its typical dynamic operating current is less than 5 μA with a battery current of less than 700 nA, enabling low power consumption suitable for prolonged battery life.
The RTC’s footprint measures 4.9 mm in length, 3.9 mm in width, and 1.5 mm in height and supports a supply voltage range of 1.8 V to 5.5 V, accommodating flexible power supply options. It also allows digital trimming to fine-tune frequency accuracy, important for precision timing applications.
