AB1815-T3 Real-Time Clock (RTC) IC with Power Management
Manufactured by ABRACON, the AB1815-T3 is a highly advanced RTC (Real-Time Clock) integrated circuit designed for precision timekeeping and power management in electronic systems. Packaged in a compact 3x3 mm QFN-16 form factor with tape packaging, this device is ideal for applications requiring ultra-low power consumption and reliable timekeeping functionalities.
Key features include:
Ultra-low supply current: 14 nA with RC oscillator, 22 nA with RC oscillator and Autocalibration, 55 nA with crystal oscillator
Standard 32.768 kHz crystal oscillator with integrated load capacitor/resistor
Comprehensive timekeeping with counters for hundredths, seconds, minutes, hours, date, month, year, century, and weekday
Alarm capabilities on all counters and programmable output clock generation (from 32.768 kHz up to 1 year)
Countdown timer with repeat function and automatic leap year calculation
Advanced calibration options: crystal calibration to ± 2 ppm, RC calibration to ± 16 ppm, and automatic RC oscillator calibration against crystal oscillator
Integrated power management features including power switch (~1Ω), system sleep manager, external reset signal monitor, and voltage detection
Supports I²C (up to 400 kHz) and SPI (up to 2 MHz) serial interfaces
Operating voltage range: 1.5V to 3.6V
Operating temperature: -40°C to 85°C
All inputs include Schmitt Triggers for noise immunity
The device is suitable for a wide range of applications including smart cards, wireless sensors and tags, medical electronics, utility meters, data loggers, appliances, handsets, consumer electronics, and communication equipment.
