AB0805-T3, Real Time Clock (RTC) IC Clock/Calendar 256B I²C, 2-Wire Serial 16VFQFN Exposed Pad

Integrated Circuits (ICs)\Clock and Timing\Real Time Clocks The AB0805-T3 is a Real Time Clock provides a ground-breaking 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 15nA), these are the first semiconductor products based on Abracon Corporation's innovative SPOT (Sub threshold Power Optimized Technology by Ambiq Micro) CMOS platform. The AB08XX 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 either an I²C or SPI serial interface for communication with a host controller. It serves as a full function RTC for host processors such as microcontrollers. The Power management features built into the AB08XX enables it to operate as a backup device in both line-powered and battery powered systems. • Sub-threshold power optimized technology by Ambiq Micro • Ultra-low supply current • 32kHz 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 (32kHz to 1/year) • Countdown timer with repeat function • Automatic leap year calculation • Integrated power optimized RC oscillator • Advanced crystal calibration to ±2ppm • Advanced RC calibration to ±16ppm • Automatic calibration of RC oscillator to crystal oscillator • Watchdog timer with hardware reset • Up to 256-byte of general purpose RAM • Automatic switchover to VBAT • External interrupt monitor • Programmable brown out detection • Programmable analogue voltage comparator
