AB1805-T3

AB1805-T3 is an AB18X5 real-time clock with a power management family that 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, this is the first semiconductor based on an innovative SPOT™ CMOS platform. This includes on-chip oscillators to provide minimum power consumption, full RTC functions including battery backup and programmable counters and alarms for timers and watchdog functions and either an I²C or SPI serial interface for communication with a host controller. An integrated power switch and a sophisticated system sleep manager with counter, timer, alarm and interrupt capabilities allow to be used as a supervisory component in a host microcontroller-based system. Application includes smart cards, wireless sensors and tags, medical electronics, utility meters, data loggers, appliances, handsets, consumer electronics, and communication equipment.
