The X5043V14IZ is a 4Kbit Serial Real-Time Clock (RTC) with EEPROM manufactured by Intersil (now Renesas). It combines a real-time clock function with non-volatile EEPROM memory on a single chip. This allows for storing and retrieving critical data, such as configuration parameters or calibration data, along with accurate timekeeping.

Applications

• Data logging systems
• Industrial control equipment
• Point-of-sale (POS) terminals
• Consumer electronics
• Metering devices
• Automotive electronics

Features

• Real-time clock (RTC) with calendar
• 4Kbit (512 x 8) EEPROM memory
• Serial interface (I2C)
• Automatic power-fail detection and switchover circuit
• Programmable alarm function
• Low power consumption
• Operating voltage: 4.5V to 5.5V
• Operating temperature range: -40°C to +85°C
• Pb-free/RoHS compliant

Benefits

• Provides accurate and reliable timekeeping
• Offers non-volatile memory for data storage
• Simplifies system design by integrating RTC and EEPROM
• Protects data during power outages
• Enables event scheduling and time-based control
• Extends battery life in portable applications
• Suitable for harsh environments

Additional Details

The X5043V14IZ uses a simple serial interface (I2C) for communication with a microcontroller or other system controller. The RTC function provides seconds, minutes, hours, day of the week, date, month, and year information. The calendar is automatically adjusted for leap years. The EEPROM memory can be used to store configuration parameters, calibration data, or other user-defined data. The automatic power-fail detection and switchover circuit ensures that the RTC continues to operate even during a power outage, by switching to a backup battery. The programmable alarm function can be used to generate an interrupt signal at a specific time, which can be used to trigger other system events. The low power consumption makes it suitable for battery-powered applications.

The 'IZ' suffix typically indicates the package type (e.g., SOIC). Datasheets should be consulted for the pinout and full operating characteristics before incorporating this part into a design.
