Verify Output
When the example code is built and programmed into the device, reset the device by pressing the
RESET button or power cycling the board.
The project output is LED3 glowing with a brightness control that changes with time (see

Low Power Demonstration
Project Description
This example project demonstrates the low power functionality of PSoC 3. The project implements
an RTC based code, which goes to sleep and wakes up on the basis of switch inputs.
The RTC uses an accurate 32-kHz clock generated using the external crystal provided on the board.
When there is a key press, the device is put to sleep while the RTC is kept active.
Hardware Connections
The project requires a 3.3 V LCD to view the time display. No extra connections are required for
project functionality. To make low power measurements using this project, refer and implement the
changes proposed in
Verify Output
In normal operation, the project displays the time starting from 00:00:00. When you press the SW2
button, the device is put to sleep. If an ammeter is connected to measure the system current (refer

The device wakes up when SW2 is pressed again and displays the time on the LCD. The following
figures show the output display.
