1. Introduction
Thank you for your interest in the CY8CKIT-030 PSoC® 3 Development Kit. This kit allows you to
develop precision analog and low power designs using PSoC 3. You can design your own projects
with PSoC Creator™ or by altering sample projects prov ided with this kit.
The CY8CKIT-030 PSoC 3 Development Kit is based on the PSoC 3 family of dev ices. PSoC 3 is a
Programmable System-on-Chip™ platform for 8- and 16-bit applications. It combines precision
analog and digital logic with a high-performance CPU. With PSoC, you can create the exact
combination of peripherals and integrated proprietary IP to meet your application requirements.
1.1 Kit Contents
The PSoC 3 Development Kit contains:
■ Development board
■ Kit CD
■ Quick Start Guide
■ USB A to Mini B cable
■ 3.3 V LCD module
Inspect the contents of the kit; if you find any part missing, contact your n earest Cypress sales office
for help.
1.2 PSoC Creator
Cypress's PSoC Creator software is a state-of-the-art, easy-to-use integrated development
environment (IDE) that introduces a game-changing, hardware and software design environment
based on classic schematic entry and revolutionary embedded design methodology.
With PSoC Creator, you can:
■ Create and share user-defined, custom peripherals using hierarchical schematic design.
■ Automatically place and route select components and integrate simple glue logic, normally
located in discrete muxes.
■ Trade-off hardware and software design considerations allowing you to focus on what matters
and getting to market faster.
PSoC Creator also enables you to tap into an entire tools eco system with integrated compiler tool
chains, RTOS solutions, and prod uction programmers to support both PSoC 3 and PSoC 5.

3. Kit Operation
3.1 Introduction
The example projects in the PSoC 3 Development Kit help you develop precision analog
applications using the PSoC 3 family of devices. The board also has hooks to enable low power
measurements for low power application development and evaluation.
3.2 Programming PSoC 3 Device
The default programming interface for the board is a USB based on-board programming interface.
To program the device, plug the USB cable to the programming USB connector J1, as shown in the
following figure.
Figure 3-1. Connect USB Cable to J1
When plugged in, the board enumerates as DVKProg. After enumeration, initiate, build, and then
program using PSoC Creator.
When using on-board programming, it is not necessary to power the board from the 12-V or 9-V DC
supply or a battery. The USB power to the programming section can be used.
If the board is already powered from another source, plugging in the programming USB does not
damage the board.
CY8CKIT-030 PSoC 3 Development Kit Guide, Doc. # 001-61038 Rev. *A 9
Kit Operation
The PSoC 3 device on the board can also be programmed using a MiniProg3 (CY8CKIT-002). To
use MiniProg3 for programming, use the connector J3 on the board as shown in the following figure.
Note The MiniProg3 (CY8CKIT-002) is not part of the PSoC 3 Development Kit contents. It can be
purchased from the Cypress Online Store.
Figure 3-2. Connect MiniProg
With the MiniProg3, programming is similar to the on-board programmer; however, the setup
enumerates as a MiniProg3.

4.2.1 Power Supply
The power supply system on this board is versatile; input supply can be from the following sources:
■ 9-V or 12-V wall wart supply using connector J4
■ 9-V battery connector using connectors BH1 and BH2
■ USB power from communications section using connector J2
■ USB power from the on-board programming section using connector J1
■ Power from JTAG/SWD programming interface using connector J3
■ Power through boost convertor that uses the input test points VBAT and GND

The board power domain has five rails:
■ Vin rail: This is where the input of the on-board regulators are connected. This domain is
powered through protection diodes.
■ 5-V rail: This is the output of the 5-V regulator U2. The rail is a fixed 5 V output regardless of
jumper settings. The voltage in this rail can be less than 5 V only when the board is powered by
the USB. This 5-V rail powers the circuits that require fixed 5 V supply.
■ 3.3-V rail: This is the output of the 3.3-V regulator U4. This rail remains 3.3 V regardless of
jumper settings or power source changes. It powe rs the circui t s requ iring fixed 3.3 V supply such
as the on-board programming section.
■ Vddd rail: This rail provides power to the digital supply for the PSoC device. It can be derived
from either the 5 V or 3.3 V rail. The selection is made using J10 (3-pin jumper).
■ Vdda rail: This rail provides power to the analog supply of the PSoC device. It is the output of a
low noise regulator U1. The regulator is a variable output voltage and can be either 3.3 V or 5 V.
This is done by changing the position on J11 (3-pin jumper).
The following block diagram shows the structure of the power system on the board.

4.2.1.1 Power Supply Jumper Settings
Figure 4-3. Jumper Settings
Two jumpers govern the power rails on the board. J10 is responsible for the selection of Vddd (digital
power) and J11 selects Vdda (analog power).
The jumper settings for each power scheme are as follows.
Powering Scheme Jumper Settings
Vdda = 5 V, Vddd = 5 V J10 in 5 V setting and J11 in 5 V setting.
Vdda = 3.3 V, Vddd = 3.3 V J10 in 3.3 V setting and J11 in 3.3 V setting.
Vdda = 5 V, Vddd = 3.3 V J10 in 3.3 V setting and J11 in 5 V setting.
Vdda = 3.3 V, Vddd = 5 V
Warning:
■ The PSoC device performance is guaranteed when Vdda is greater than or equal to Vddd. Fail-
ure to meet this condition can have implications on the silicon performance.
■ When USB power is used, ensure a 3.3 V setting on both analog and digital supplies. This is
because, the 5 V rail of the USB power is not accurate and is not recommended.
4.2.1.2 Grounding Scheme
The board is designed considering analog designs as major target applications. Therefore, the
grounding scheme in the board is unique to ensure precision analog performance.
There are three types of ground on this board:
■ GND - This is the universal ground where all the regulators are referred. Both Vssd and Vssa
connect to this ground through a star connection.
■ Vssd - This is the digital ground and covers the digital circuitry present on the board, such as
RS232 and LCD.
■ Vssa - This is the analog ground and covers the grounding for analog circuitry present on the
board, such as the reference block.
Can be achieved, but is an invalid condition because the PSoC 3 silicon
performance cannot be guaranteed.
When creating custom circuitry in the prototyping area provided on the board, remember to use the
Vssa for the sensitive analog circuits and Vssd for the digital ones.
Port E on the board is the designated analog expansion connector. This connector brings out
ports 0, 3, and 4, which are the best performing analog ports on PSoC 3 and PSoC 5 devices. The
expansion connector, port E, has two types of grounds. One is the analog ground (GND_A in silk
