2.10  Battery Backup SRAM 

 

UNO-2170 provides 512 KB of battery backed SRAM. This ensures that 
you have a safe place to store critical data. You can now write software 
applications without being concerned that system crashes will erase criti- 
cal data from the memory. 

There is a BTRY LED in the front panel of the UNO-2170, please replace 
the lithium battery with a new one if the BTRY LED is activated.
