DESCRIPTION

· The RS5C372A is a CMOS real-time clock IC with a 2-wire I2C bus interface for serial communication with a CPU.
· It features low current consumption (0.5 µA typical at 3V) due to constant voltage oscillation.
· Includes a 32-kHz clock output and a time trimming circuit for precision adjustments.
· Packaged in an ultra-compact 8-pin SSOP, ideal for space and power-sensitive applications.

FEATURES

· Operates from 1.3V to 6.0V with a supply current as low as 0.5 µA.
· I2C bus interface supports up to 400kHz with a 7-bit address.
· Includes BCD coded clock and calendar counters, and supports periodic and alarm interrupts.
· Features oscillation halt sensing for data validation and selectable 32.768kHz or 32.000kHz oscillator.
· Offers second digit adjustment, automatic leap year recognition, and selectable 12/24-hour time display.

APPLICATIONS

· Suitable for compact, low-power devices requiring precise timekeeping.
· Ideal for integration into systems needing periodic or alarm-based interrupts.
· Used in applications where data validity at power-on is crucial.
· Applicable in environments requiring high precision time adjustments and low power consumption.
