ab 1 8xx series real time clock module date of issue: sept . 10 th , 2012 3. 0 x 3.0 mm esd sensitive page ( 3 ) of ( 13 ) abracon drawing # revision #: initial release power management features built into the ab18xx enable it to operate as a backup de vice in both line - powered and battery - powered systems. an integrated power control module automatically detects when main power (vcc) falls below a digitally - selectable threshold and switches to backup power (vbat). up to 256b of ultra - low leakage ram en able the storage of key parameters when operating on backup power. the ab18xx is the first rtc to incorporate a number of more advanced power management features. in particular, the ab18xx includes a finite state machine (integrated with the power control block) that can control a host processor as it transitions between sleep/reset states and active states. digital outputs can be configured to control the reset signal or in terrupt input of the host controller with digitally - tunable timing. the ab18xx additionally in tegrates a power switch with <1 impedance that can be used to cut off ground current on the host microcontroller and r educe sleep current to <1 na. the ab18xx parts can wake - up a sleeping system using internally generated timing interrupts or externally generated interrupts generated by digital inputs (e.g., using a pushbutton). the aforementioned functionality enables users to seamlessly power down host processors, leaving only the energy - efficient ab18xx chip awake. the ab18xx also includes digita lly - tunable voltage monitoring for brown - out detection and power - on reset. 3. ab18xx example applications the ab18xx enables a variety of system implementations in which the ab18 xx can control power usage by other elements in the system. this is typically used when the entire system is powered from a battery and minimizing total power usage is critical. the backup ram in the ab18xx can b e used to hold key mcu parameters when it is powered down. 3.1 vss power switched in the recommended implementation, the internal power switch of the ab18xx is used to completely turn off the mcu and/or other system ele ments. in this case the psw/nirq2 output is configured to generate the sleep function. under normal circumstances, the psw/nirq2 pin is pulled to vss with less than 1 ohm of resis tance, so that the mcu receives full power. the mcu initiates a slp operation, and when the ab18xx enters sleep mode the psw/nirq2 pin is opened and power is completely removed from the mcu. this results in significant additional power savings relative to the other alternatives. a variety of interrupts, including alarms, timers and external interrupts created by a pushbutton as shown, ma y be used to exit sleep mode and restore mcu power. the ram of the ab18xx may be used to retain critical mcu parameters. ab1 8xx v c c v s s i r q v c c a m 1 8 x x m c u i 2 c / s p i v s s x o x i e x t i f o u t / n i r q p s w / n i r q 2 r
