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

CBC-EVAL-06 has the following elements:

•

DS-72-22 Rev C

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.
