Texas Instruments Development Kit for TM4C129x,Tiva™ ARM® Cortex™ -M4 Microcontroller DK-TM4C129X DK-TM4C129X Datenbogen
Produktcode
DK-TM4C129X
– Hibernation clock input failure detect with a switch to the internal oscillator on detection
■ RTC operational and hibernation memory valid as long as V
DD
or V
BAT
is valid
■ Low-battery detection, signaling, and interrupt generation, with optional wake on low battery
■ GPIO pin state can be retained during hibernation
■ Clock source from an internal low frequency oscillator (HIB LFIOSC) or a 32.768-kHz external
crystal or oscillator
■ Sixteen 32-bit words of battery-backed memory to save state during hibernation
■ Programmable interrupts for:
– RTC match
– External wake
– Low battery
