PT7C43190WE

The PT7C43190WE is an IC (Integrated Circuit) component that offers various features and functionalities. Here is an overview of its key features: 1. Real-Time Clock (RTC): The PT7C43190WE is primarily designed as an RTC module. It accurately keeps track of time and date, including seconds, minutes, hours, days, months, and years. It supports both 12-hour and 24-hour time formats. 2. Alarm Function: This IC component includes an alarm feature that can be configured to trigger an interrupt or a set output when a specific time is reached. The alarm can be set for a single occurrence, daily, on specific days of the week, or monthly. 3. I2C Interface: The PT7C43190WE is equipped with an I2C (Inter-Integrated Circuit) interface, also known as TWI (Two-Wire Interface), which simplifies communication with microcontrollers or other devices. It allows for easy read and write operations to control and retrieve data from the IC. 4. Battery Backup: The IC has a built-in power supply circuitry that allows it to operate on a backup battery when the main power is disconnected or unavailable. This ensures that the real-time clock continues to function and retain timekeeping data during power outages. 5. Low Power Consumption: The PT7C43190WE is designed to be power-efficient, enabling long battery life
