The Texas Instruments BQ32000DR is a Real Time Clock (RTC) device in their Clock/Timing - Real Time Clocks product category. An RTC is an electronic component responsible for keeping track of the current time and date, even when the main system is powered off. RTCs are commonly found in various applications, such as computers, servers, embedded systems, and consumer electronics.
Key features of the BQ32000DR include:
1. Accurate timekeeping: The BQ32000DR integrates a 32.768kHz crystal oscillator and features timekeeping functions for hours, minutes, seconds, day of the week, day, month, and year.
2. Leap-year compensation: This RTC device offers leap-year compensation up to the year 2100 to ensure accurate calendar tracking, including February 29th during leap years.
3. Low power consumption: The BQ32000DR is designed for low power consumption, featuring a typical timekeeping current of 190nA and a battery-backed operation to maintain accurate timekeeping during power outages or system shutdowns.
4. Alarm functionality: An alarm function is provided, which can be programmed to trigger at a specified date and time.
5. Versatile interface: The device uses an I2C serial interface for communication with a microcontroller or other host device, facilitating configuration, control, and data transfer.
6. Supply voltage: The BQ32000DR operates with a supply voltage ranging from 2.7V to 5.5V, making it suitable for various power supply configurations.
7. Package: The RTC comes in a compact 8-pin SOIC package, making it ideal for space-constrained applications.
