CBC-EVAL-06
EnerChip™ CC Real-Time Clock Evaluation Kit
System Features and Overview
CBC-EVAL-06 is a demonstration kit featuring the
Cymbet EnerChip CBC3112 backup power and
battery management circuit coupled with the Micro
Crystal low power RV-2123 real-time clock (RTC) with
integrated crystal.
The kit demonstrates just how compact an RTC and
backup power solution can be using the low profile
surface mount devices from Cymbet and Micro Crystal.
The combined board space of the two-chip solution
including RTC, crystal oscillator, rechargeable backup
power source, and power management circuits, is
only 0.65 cm
2
.
CBC-EVAL-06 has the following elements:
•
Solid state rechargeable energy storage in low
profile surface mount package, for real-time clock
backup power
Integrated battery management that controls
battery charging and discharge cutoff, ensuring
maximum service life of on-board storage cells
Integrated real-time clock and crystal oscillator in
small ceramic surface mount package with SPI
bus
USB connector for easy demonstration on
personal computer
Input/output access to board for easy connection
to external microcontroller

Smallest RTC Power Backup Footprint
As shown above in Figure 1, the CBC-EVAL-06
demonstrates an extremely compact RTC power backup
solution. The EnerChip CC CBC3112 is on the left and
the Micro Crystal 2123 is on the right inside the white
box. The block diagram of this simple two chip solution
is shown in Figure 2.

EVAL-06 Graphical User Interface
The CBC-EVAL-06 includes an easy to use PC based
software application that communicates with the USB
stick. Users can set the time of day, date and count-
down timer values to experiment with RTC power-back-
up. The software works with Microsoft Windows XP
and Windows 7 operating systems. Once the EVAL-06
USB stick is inserted into the PC, the Connect button
is clicked in the GUI. This establishes communication
over the USB port and the time, date and countdown
selections are written to the RTC. The EVAL-06 can then
be removed from the PC and the RTC will be powered by
the EnerChip CC CBC3112.

Getting Started
For first time users who have not installed the demonstration software, follow these steps:
Insert the EVAL-06 Kit CD-ROM into the CD drive.
If the Microsoft .NET Framework Client Profile has not been loaded, a window will appear as shown below. Click
‘Accept.’
After Framework loads, click ‘Yes’, on Setup. This will reboot the computer.
When the ‘Welcome to the RTC Setup Wizard’ window appears, click ‘Next.’
