The BQ3285P-SB2 is one of the latest series of Real Time Clock (RTC) devices from Texas Instruments. It is designed to provide electronic devices with an accurate, continuous time reference that is independent of power cycles and other external events. This can be used for events such as data logging, calendar functions, counting functions and other duties that require an accurate and reliable long-term clock.

Application Fields

The BQ3285P-SB2 is well-suited for applications where users need both time-of-day accuracy and periodic signaling. It is useful for supporting, among other things, data logging, calendar operations, counting functions, and time-stamping. Some of the most popular applications for this part include embedded systems, automotive electronics, HVAC systems, and consumer electronics.

Working Principle

At its heart, the BQ3285P-SB2 is powered by a 32.768 kHz oscillator that provides a "+/- 1 ppm" timebase, meaning it stays accurately on time to within a minute per month. To support various applications, the device includes four independent timekeeping channels (1 kHz, 4 kHz, 8 kHz, and 32 kHz). These timekeeping channels, along with a programmable interrupt capability, give the device the necessary flexibility to match application-specific requirements. By keeping track of time and autonomously generating periodic timekeeping events, the BQ3285P-SB2 allows users to spend less time debugging timing issues and worrying about interrupt logic.

The BQ3285P-SB2 also features support for reset detection, an adjustable alarm which allows for an output pulse width of up to 10 minutes, and programmable input/output pins. It is also backed by a guaranteed supply voltage range of 2.7V to 5.5V, making it versatile for a wide range of applications.

Conclusion

The BQ3285P-SB2 is an RTC device from Texas Instruments that is perfect for a wide range of applications where users need both time-of-day accuracy and periodic signaling. The device is powered by an accurate, continuous time reference that is highly reliable and independent of power cycles and other external events. Its timekeeping and interrupt logic capabilities provide the flexibility to match application-specific requirements. With its adjustable alarm, reset detection, and programmable input/output pins, the BQ3285P-SB2 is a powerful, versatile solution for applications in embedded systems, automotive electronics, HVAC systems, and consumer electronics.
