Product specifications

Artasie Real-Time Clock Family - AM0805

The Ambiq Artasie Real-Time Clock family AM0805 provides a groundbreaking combination of ultra-low power coupled with a highly sophisticated feature set. With power requirements significantly lower than any other industry RTC (as low as 14 nA), these are the first semiconductors based on Ambiq's innovative SPOT® (Subthreshold Power Optimized Technology) CMOS platform.

The AM0805 includes on-chip oscillators to provide minimum power consumption, full RTC functions including battery backup and programmable counters and alarms for timer and watchdog functions, and a PC serial interface for communication with a host controller.

Features:

Ultra-Low Supply Current
- 14 nA with RC oscillator
- 22 nA with RC oscillator and Autocalibration
- 55 nA with crystal oscillator

Baseline Timekeeping

- 32.768 KHz crystal oscillator with integrated load capacitor/resistor
- Counters for hundredths, seconds, minutes, hours, date, month, year, century, and weekday
- Alarm capability on all counters
- Programmable output clock generation (32.768 KHz to 1 year)
- Countdown timer with repeat function
- Automatic leap year calculation

Advanced Timekeeping
- Advanced crystal calibration to ± 2 ppm
