PC6-TANGO • CompactPCI
®
PlusIO • Intel® Atom™ E39xx Processor (APL-I SoC)
Real-Time Clock
The PC6-TANGO is provided with a time-of-day clock and 100-year calendar, integrated into the APL-I
SoC. A battery on the board supplies the clock circuitry whenever the computer main power is turned
off. The PC6-TANGO uses a holder to retain a BR2032 lithium coin cell, giving an autonomy of more
than 5 years.
Alternately a leaded BR2032 battery can be soldered directly to the board for increased ruggedness,
or if the PC6-TANGO PCB shall be coated.
In applications were the use of a battery is not permitted, a SuperCap can be soldered instead of the
battery.
