The CV194CPAG is a Real-Time Clock (RTC) IC manufactured by Renesas Electronics America. RTCs are essential components in electronic devices for keeping track of the current time, date, and often alarm settings, even when the main power is off. They are typically powered by a backup battery. The CV194CPAG is designed for low power consumption and high accuracy, making it suitable for a wide range of applications.

Applications:

• Industrial control systems
• Point-of-sale (POS) terminals
• Medical devices
• Automotive electronics
• Consumer electronics (e.g., clocks, timers, appliances)
• Data loggers

Features:

• Real-Time Clock: Keeps track of seconds, minutes, hours, days, date, month, and year.
• Low Power Consumption: Extends battery life in backup mode.
• I2C Interface: Simplifies communication with microcontrollers and other devices.
• Alarm Function: Allows setting alarms for specific times and dates.
• Calendar Function: Automatically adjusts for leap years.
• Battery Backup: Maintains timekeeping during power outages.

Benefits:

• Accurate Timekeeping: Provides reliable time and date information.
• Low Power Operation: Minimizes battery drain.
• Easy Integration: Simple I2C interface for easy connection to microcontrollers.
• Flexible Alarm Settings: Allows for customized alarm functions.
• Robust Operation: Ensures reliable performance in a variety of environments.

Additional Details:

The CV194CPAG typically operates with a supply voltage of 3.3V or 5V. The I2C interface allows for easy reading and writing of time and date data. The device often includes a crystal oscillator for accurate timekeeping, usually 32.768 kHz. The battery backup input allows for connection to a small battery to maintain timekeeping when the main power is off. The alarm function can be programmed to generate an interrupt signal when the alarm time is reached. Detailed specifications, including operating voltage range, power consumption, and I2C address, can be found in the Renesas Electronics datasheet for the CV194CPAG. The package type is typically a small surface-mount package, such as SSOP or TSSOP. The device meets industry standards for RoHS compliance.
