The Alarm RTC, part number 45AC7406, is a serial access real-time clock designed for low-power applications. It operates within a voltage range of 2.0 to 5.5 V and features an I2C interface with a maximum clock speed of 400 kHz. The device includes counters for various time units, including seconds, minutes, hours, days, and years, and supports a programmable alarm and interrupt function. This component integrates a 32 KHz crystal oscillator with a load capacitance of 12.5 pF, ensuring high stability and performance. It provides a square wave output that can be programmed from 1 Hz to 32 KHz, which can be utilized to drive microcontrollers in low-power modes. The operating temperature range is from -40 to 85 ¬8C, and it has a low operating current of 200 ¬µA, making it suitable for battery-powered devices. The product is housed in an 8-pin SOIC package and is compliant with ECOPACK¬Æ standards.
