Description

The PCF85063ATT/AJ is a low-power, real-time clock (RTC) and calendar IC from NXP Semiconductors. It provides accurate timekeeping with I²C interface support and operates at 1.8V to 5.5V, making it suitable for battery-powered applications.
Key features:
- Ultra-low power consumption (~250nA in battery backup mode).
- Timekeeping accuracy with automatic leap-year correction.
- Alarm, timer, and interrupt functions for event-triggered wake-ups.
- Integrated oscillator (no external crystal needed for basic operation).
- Small TSSOP-8 package, ideal for space-constrained designs.
Common applications include wearables, IoT devices, and embedded systems requiring precise timekeeping with minimal power draw.
For detailed specs, refer to the datasheet on NXP’s website.
