In which mode MC1321x should operate to increase the battery life time?

[lekkal]

Hi All,

I have designed a MC13213 board which is suppose to work with coin cell battery (CR2354,500mAh) atleast for 12months.When it is in communication with other module i.e. either in Tx or Rx it is drawing ~50mA and in idle mode current is 7mA.If I keep the module continuously in idle mode then battery life time will be just 3days (500/7 = 72hours = 3days). If I use two AA batteries life time will be 11days(1800/7 = 257hours = 11days). In which mode  should it operate to increase the battery life time? Please give me the complete details off different modes like current,RAMstatus,I/O ports status and etc

Thanks & Regards,

Lekkal
