 # RTC Subsystem
 
 The RTC subsystem also keeps the actual clock (date / time) running, powered by a CR2032 battery, (which needs to be installed on the portapack board!), even when the unit is not connected to an USB power source.

+This persistent memory is part of the **RTC (Real Time Clock) subsystem**, inside the LPC43xx chip on the portapack hardware.
 
-The **backup_ram region** is defined in `/firmware/common/memory_map.hpp` and labeled as "LPC_BACKUP_REG_BASE" starting at address **0x40041000**

 ### data_t struct
 
 The Portapack firmware uses the backup_ram region to store several uint32_t (and one uint64_t) variables, inside a struct, called "data_t", declared on /firmware/common/portapack_persistent_memory.cpp
