EVAL-05 Operational Modes
The CBC-EVAL-05 board can be used in seven different ways:
1. CBC3150 only - Connect to pins 1-12.
2. CBC3112 only - Connect to pins 13-24 or rotate the EVAL-05 so that pin 13 is inserted into socket pin 1
3. CBC050 only - the EnerChip 50 µAh battery is tested alone. Do not connect pins 1 and 4 together; pin 1 is
4. CBC012 only - the Enerchip 12 µAh battery is tested alone. Do not connect pins 13 and 16 together; pin
5. CBC3150 controlling the CBC012 - The CBC3150 can be used to control external EnerChips, including the
6. CBC3112 controlling the CBC050 - The CBC3112 can be used to control external EnerChips, including the
7.

Place the 24-pin EVAL-05 module into solderless breadboard or socket with pin 1 in pin 1.
Note that if only one EnerChip CC is to be evaluated at a time, only pins 1 to 12 need to be connected on
the test board. With board pin 1 in socket pin 1, the CBC3150 is accessible. To access the CBC3112, turn
the EVAL-05 180 degrees and place EVAL-05 pin 13 in socket pin 1.
Tie V
When operating under main power, LED D1 (CBC3150) or D2 (CBC3112) will be illuminated. When
operating in battery backup mode, LED D1 (CBC3150) and D2 (CBC3112) will not be illuminated.

Tie the RESET pin to the interrupt pin of a microcontroller if desired. When operation is under battery
backup mode, the LED will not be illuminated.
Allow the EnerChip CC to charge for at least 30 minutes before attempting to use backup power.
