Introduction
1.4
PSoC Development Board
The CY8CKIT-001 PSoC Development Board is designed to aid hardware, firmware, and software
developers in building their own systems around Cypress’s PSoC devices. The flexibility to configure
the power domains is one of the foremost features of this board. Input power to the board is from one
of two sources:
■
12 V 1-A power supply adapter
■
9-V alkaline battery (not included)
This full-featured board incorporates three onboard linear regulators that power peripherals and
PSoC processor modules at voltages between 1.7 V and 5.0 V. These regulators include a fixed 5 V
1-A linear regulator, a fixed 3.3 V 300-mA linear regulator, and a 1.5 V to 3.3 V for 3.3-V supply and
1.5 V to 5 V for 5-V supply adjustable regulator. The board also provides the ability to separate the
PSoC core VDD rail into two separate rails, analog and digital. In addition, the board is able to
separate the I/O VDD rails, giving the flexibility to power the I/O ports at different voltages.
The board is equipped with a 2×16 alphanumeric LCD module capable of 1.8 V to 5.0 V I/O. In
addition, there is a mini-B full-speed USB interface and a female DB9 serial communications
interface. Also included is a 12-pin wireless radio module interface, which can be used to develop
CyFi™ low-power RF or other embedded RF solutions with this kit. The board also has a prototyping
area containing a small breadboard, complete with I/O port sockets nearby, multipurpose LEDs,
mechanical push buttons, and a multipurpose variable resistor. In addition, three capacitive sensing
elements (two buttons and a five segment slider) are included on the board to allow the evaluation of
CapSense® applications.
The board has four general-purpose I/O (GPIO) expansion slots, allowing the I/O to expand to external boards.
The board is designed with modularity in mind and, as a result, supports removable processor modules. This allows you to plug different PSoC processor modules into the board based upon the
desired features of both 8-bit and 32-bit PSoC devices.
Note
1.4.1
■
The PSoC device may get hot or damaged if many I/O pins are configured as strong drive with
initial state HIGH and grounded externally using wires.
■
The PSoC device may get hot or damaged if many I/O pins are configured as strong drive with
initial state LOW and connected to Vcc externally using wires.
Default Switch and Jumper Settings
Jumpers on the CY8CKIT-001 PSoC development board have a default setting to operate at 3.3 V.
For default configuration, each of the jumpers must be set according to these instructions.
Note All CY8C28 and CY8C29 family processor module code examples are configured for 5 V. Configure the board to 5 V, before creating the code examples.

Loading My First PSoC Project
The CY8CKIT-001 PSoC Development Kit supports projects across the PSoC 1, PSoC 3, and
PSoC 5 architectures. This section walks you through the high-level design process for opening,
building, programming, and running your first PSoC project using this kit.
Before beginning, follow each of these steps to make certain that your software and hardware
environments are properly configured and ready for these projects:
1. Install PSoC Designer using the steps listed in Installing PSoC 1 Development Software on
page 8.
2. Install PSoC Creator using the steps listed in Installing PSoC 3 Development Software on page 8.
3. Connect the MiniProg3 into your PC using the supplied USB cable. When you connect the
MiniProg3, Microsoft Windows® may indicate that it has found new hardware. All required drivers
are installed as part of the PSoC Programmer installation process; however, if Windows opens
the driver installation dialog boxes, accept the defaults and allow Windows to automatically find
the appropriate driver.
4. Close any open PSoC Creator or PSoC Designer applications and projects.
5. Configure the PSoC development board (jumper settings and switches) in its default configuration, as described in Default Switch and Jumper Settings on page 10.
6. Use the PSoC CY8C28 family processor module or PSoC CY8C29 family processor module for

My First PSoC 1 (CY8C29) Project on page 20).
7. Use the PSoC CY8C38 family processor module for the PSoC 3 version of your first PSoC
project (My First PSoC 3 (CY8C38) Project on page 25).
8. Use the PSoC CY8C55 family processor module for the PSoC 5 version of your first PSoC
project (My First PSoC 5 (CY8C55) Project on page 28).
9. For a PSoC 1 project, use the ISSP header on the PSoC CY8C28 family processor module or
PSoC CY8C29 family processor module and connect the MiniProg3 ISSP port.
10.For a PSoC 3 or PSoC 5 project, use the JTAG ribbon cable. Connect the ribbon cable to the
MiniProg3 and the CY8C38 family processor module or CY8C55 family processor module into
the header labeled PROG on the processor module.
Note The MiniProg3 should not be "hot plugged" into processor modules that are attached to the
PSoC development board. In other words, do not plug the ribbon cable of the MiniProg3 into the
processor module while code is actively running on the module. Doing so may cause the PSoC
device to unintentionally reset. Power down the PSoC development board and module by
unplugging the power supply from the development board before attaching the MiniProg3 device
to the module board. When the ribbon cable is attached to the module board, power the system
by plugging in the power supply to the PSoC development board. This will avoid any undesirable
PSoC device resets.
11. Power the PSoC development board using the 12-V AC power supply adapter.

3.1.3
ADC to UART with DAC
This project demonstrates sine wave generation by using a 6-bit digital-to-analog converter (DAC).
The sine wave period is based on the current value of the ADC. The firmware reads the voltage
output by the DVK board potentiometer and displays the raw counts on the DVK board character
LCD display similar to those shown in the previous project. A 6-bit DAC outputs a table generated
sine wave at a frequency proportional to the ADC count. The frequency outputs to an oscilloscope. A
38400 Baud UART outputs the current ADC count as ASCII formatted into a hexadecimal number.
3.1.3.1
Creating ADC to UART with DAC Project
1. Follow steps 1 to 10 in section 3.1.1.1 on page 33; change the project name to
Ex3_ADC_to_UART_with_DAC.
2. In the User Modules window expand the ADCs folder and right-click DelSigPlus; select Place.
A window opens with multiple options for the DelSigPlus UM. Here, the DS1128 configuration is
used. Scroll down in the window to verify that this is the case.
3. Click OK.
4. Verify that the UM is placed in ASC10.
5. In the User Modules window, expand the Amplifiers window. Right-click PGA and select Place.
Ensure that the PGA is placed in ACC00.

3.2.3
ADC to LCD with DAC and UART
This project demonstrates sine wave generation by using a 6-bit DAC. The sine wave period is
based on the current value of the ADC. The firmware reads the voltage output by the DVK board
potentiometer and displays the raw counts on the DVK board character LCD display similar to those
shown in the previous project. A 6-bit DAC outputs a table generated sine wave at a frequency
proportional to the ADC count. The frequency is in the approximate range of 15 Hz to 350 Hz and
outputs to port to observe on scope. A 38400 Baud UART outputs the current ADC count as ASCII
formatted into a hexadecimal number.

My First PSoC 3 / PSoC 5 Project
This project demonstrates basic hardware and software functionality with the PSoC 3 or PSoC 5
device. It flashes two LEDs independently, one using hardware, the other with software. The hardware LED uses a hardware enabled digital port and a PWM to generate a duty cycle and flash the
LED. The software LED uses a software enabled digital port and a simple delay in the main.c to flash
the LED at a known rate.

ADC to UART with DAC
This project demonstrates sine wave generation by using an 8-bit DAC and DMA. The sine wave
period is based on the current value of the ADC value of the potentiometer.
The firmware reads the voltage output by the DVK board potentiometer and displays the raw counts
on the DVK board character LCD display similar to that shown in the previous project. An 8-bit DAC
outputs a table generated sine wave to an LED using DMA at a frequency proportional to the ADC
count. A 9600 Baud 8N1 UART outputs the current ADC count as ASCII formatted into a
hexadecimal number.
The following instructions assume that you have completed My First PSoC Project and ADC to LCD
Project and therefore have a basic understanding of the PSoC Creator software environment.

SAR ADC (PSoC 5 Only)
This project demonstrates sine wave generation by using an 8-bit DAC and DMA. The sine wave
period is based on the current value of the ADC value of the potentiometer.
The firmware reads the voltage output by the DVK board potentiometer and displays the raw counts
on the DVK board character LCD display similar to that shown in the previous project. An 8-bit DAC
outputs a table generated sine wave to an LED using DMA at a frequency proportional to the ADC
count. A 9600 Baud 8N1 UART outputs the current ADC count as ASCII formatted into a
hexadecimal number.
The following instructions assume that you have completed My First PSoC Project and ADC to LCD
Project and therefore have a basic understanding of the PSoC Creator software environment.
This code example uses the following components:
3.3.6.1
■
SAR ADC (Component Catalog Analog ADC SAR ADC)
■

PSoC Development Board
A.1.1
Factory Default Configuration
A.1.1.1
Power Supply
The board has several power nets. Following are the definitions of the different power nets.
VIN (9 V or 12 V) - This is the input power before it is fed to any of the regulators. A 9-V to 12-V
power supply adapter or a 9-V battery is used as the source.
VREG (5 V) - This is fed by VIN and is the output of the onboard 5-V regulator. VREG can be
selected as the main 5-V source by using the J8 header.
VBUS (5 V) - This is power derived from the USB interface via a USB host. VBUS can be selected
as the main 5-V source by using the J8 header.
VDD (3.3 V or 5 V) - This is fed by VREG, VBUS, or the onboard 3.3-V regulator. VDD can be chosen either to be 3.3 V or 5 V by the simple positioning of the VDD select switch.
VADJ (1.5 V to 3.3 V for 3.3-V supply and 1.5 V to 5 V for 5-V supply) - This is fed by VDD and is the
output of the onboard adjustable regulator. It is mainly used when the PSoC core must be powered
at lower voltages. An adjustable resistor R11 is used for adjusting the voltage.
VDD DIG - This is power derived from either VDD or VADJ. It is used to power the PSoC core. The
source for VDD DIG can be chosen as VDD or VADJ using the J7 header.
VDD ANLG - This is power derived from either VDD or VADJ. It is mainly used to separate the analog power from the digital power. The source for VDD ANLG can be chosen as VDD or VADJ using
the J6 header.
VDDIO - This is power derived from either VDD or VADJ. It is used to power digital I/O on the PSoC
device. There are four sections of GPIO, which can be powered to 5 V, 3.3 V, or VADJ using four
headers. It enables you to power the PSoC GPIOs at different voltages.

A.1.2.6
Setting a 3.3-V Supply from VBUS
Due to the nature of the PSoC development board, powering the system from USB 'VBUS' can
potentially reset other USB devices on the same hub.
By design, the PSoC development board is capable of drawing more than 500 mA of current during
normal operation, which exceeds USB bus power limits. Additionally, the development board
exceeds inrush current limits due to 'VBUS' capacitance greater than 10 uF. As a result, plugging the
PSoC development board into a USB hub can potentially cause other devices on the same hub to
reset due to excessive inrush currents. Take care when powering the PSoC development board from
'VBUS'. It is good practice to plug the board into a host root hub, or a "self-powered" external hub
when doing USB development. Bus powered applications done outside the realm of the PSoC development board should comply with the USB specification for inrush current limits and recommended
bulk capacitance on 'VBUS'. See the Universal Serial Bus Specification Revision 2.0 for more
details.
1. Place the jumper on J8 header to select VBUS as the source.
2. Move the VDD select switch to select 3.3 V.
3. Place the jumper on J6 header to select VDD as source for VDD ANLG.
4. Place the jumper on J7 header to select VDD as source for VDD DIG.

This header allows you to select the 5 V source from either the onboard 5 V regulator (VREG) or
from the USB 5 V rail (VBUS).
A.1.2.10
VDD Select Switch
This switch allows you to select either 5 V or 3.3 V. VDD feeds VDD DIG, VDD ANLG, and VDDIO.

A.1.2.11
J7 - VDD DIG Select
This header allows you to select the PSoC core source power. To power the PSoC core at either 5 V
or 3.3 V (based on the position of the VDD select switch), place the jumper on the upper two pins. To
power the PSoC core at lower voltages (1.7 V to 4.95 V), place the jumper on the lower two pins.
When the jumper is on the lower two pins, you must adjust R11 to tune the adjustable regulator to
output the desired voltage.
A.1.2.12
J6 - VDD ANLG Select
To separate the analog power from the digital power, you can position the jumper on the upper two
pins to source analog power at 5 V or 3.3 V (based on the position of the VDD select switch), or on
the lower two pins to source analog power at lower voltages (1.5 V to 3.3 V for 3.3-V supply and
1.5 V to 5 V for 5-V supply).
A.1.2.13
R11 - Adjustable Regulator Variable Resistor
This adjustable resistor is used to tune the VADJ voltage. Turning this variable resistor swings the
VADJ voltage between 1.6 V and 3.29 V when the VDD select switch is in the 3.3 V position. When
the VDD select switch is in the 5 V position, turning this variable resistor swings the VADJ voltage
between 1.7 V and 4.95 V.

CY8C55 family modules have a 2200-pF capacitor connected between P15[5] and ground. These
configurations provide an external modulator capacitor for CapSense designs. To use P2[7] on
CY8C38 family modules or P15[5] on CY8C55 family modules for anything other than CapSense, it
is recommended that C18 on these modules be removed, to avoid disrupting digital or analog signals on this I/O pin.

Board Specifications and Layout
A.1.3.2
P15 - DB9 Serial Communications Port
This is a standard female DB9 serial communications connector. Four signals are brought from the
RS-232 transceiver to receptacle P16. These signals are Rx, Tx, Clear To Send, and Request To
Send. To connect these signals to the PSoC I/O pins, use wires to jumper from P16 to P19, where
sockets for ports zero and one are available.

J10 - Serial Port Power
Header J10 must be connected to use the serial communications port. Placing a jumper on J10 provides VDD power to the RS-232 transceiver. This power can be either 3.3 V or 5 V, depending on the
position of the VDD select switch.
A.1.3.4
J9 - Full Speed USB Port
The board has a mini-B full speed USB connector. There are also two test points for the differential
pair signals D– and D+. These signals are routed to the processor module socket P1, pins 6 and 8
respectively. The power net VBUS is brought into the board through this interface.
A.1.3.5
P17 - Artaflex WirelessUSB LP Radio Module Receptacle
Receptacle P17 is used specifically for the Artaflex AWP24S WirelessUSB module. Eight signals are
routed from this receptacle to P12 receptacle. These signals are four serial peripheral interface (SPI)
signals MISO (master-in-slave-out), MOSI (master-out-slave-in), nSS (slave select), SCK (serial
clock), an IRQ (interrupt request) and RD_RESET (radio reset). The other two signals are radio
transmit and receive signals.
Note These I/O signals must not be greater than 3.3 V.

J14 - Wireless Radio Module Power
Header J14 must be connected to use the Artaflex radio module. Placing a jumper on J14 provides
3.3 V power to the P17 module socket. This power is drawn directly from the 3.3 V regulator.
A.1.3.7
R20 - Multipurpose Variable Resistor
The board is equipped with a 10 k thumbwheel variable resistor referenced to ground. The high
side of the resistor is tied to jumper J11. The wiper is tied to a receptacle pin on P14.
A.1.3.8
J11 - Variable Resistor Power
Header J11 must be connected to use the variable resistor. Placing a jumper on J11 provides VDD
ANLG power to the high side of the resistor.
A.1.3.9
SW1 and SW2 - Multipurpose Push Button Switches
The board has two multipurpose mechanical push buttons, SW1 and SW2, that are referenced to
ground. The other sides of the switches are tied to receptacle pins on P14. The switches follow an
inverted logic as they connect ground to receptacle pins on P14 when pressed.
A.1.4
LCD Module
The board has a 2×16 alpha-numeric LCD. I/Os of the module are connected to port two of the
PSoC device and are routed to the processor module socket P2. This LCD is rated for 5 V. However,
the I/Os have a level translator inline so that signaling may be as low as 1.8 V and still be recognized
by the LCD. The header J12 must be connected for the LCD module to be powered; otherwise, it
removes power from the level translator. If the LCD module is removed, the receptacle pins of P18
can be used as port 2.
Note You can connect R40 (0E resistor, no load part) or short the pads given for R40 to switch the
LCD back-light on. The current consumption of the LCD with backlight is around 70 mA; this should
be considered when you budget the power supply of the design. You may use the backlight LCD
from Lumex Inc (part number: LCM-S01602DSF/A).

R31 - LCD Contrast Adjustment
The board is equipped with an LCD contrast adjustment resistor R31. Turning the wiper counterclockwise increases the contrast, while turning the wiper clockwise decreases the contrast.
A.1.4.2
J12 - LCD Module Power
Power for the LCD module is provided through header J12. Placing a jumper on the upper two pins
shorts the VCC pin of the module to ground. Placing the jumper on the lower two pins provides 5 V
to the VCC pin of the module. This 5 V power is taken directly from the onboard 5 V regulator.
A.1.5
CapSense Elements
The prototyping area has three capacitive sensing elements. There are two CapSense buttons connected directly to port zero pins. In addition, there is a five-segment CapSense slider also connected
directly to port zero. Series resistors are placed on these port zero I/Os and should be loaded with
appropriate values. A value of 0 is used for general-purpose CapSense applications, but a value of
560 should be used to achieve best performance. The board is loaded with 0 series resistors by
default. The presence of CapSense elements does not affect the general purpose use of port zero
pins.
A.1.6
Processor Module
A.1.6.1
J2, J3, J4, and J5 - VDDIO Select
These four headers allow you to power the PSoC GPIOs at different voltages. For instance, some of
the I/O may be powered at 5 V, some at 3.3 V, and some at 1.8 V. There are four blocks of GPIO,
each having its own source power. Each VDDIO header provides power to specific GPIOs and is
selectable from VDD, 3.3 V, or VADJ. For details on which GPIOs are powered by which VDDIO
header, see the datasheet for the PSoC device used with this board.

CY8CKIT-001 PSoC Development Kit Guide, Doc. # 001-48651 Rev. *J
Board Specifications and Layout
For example, VDDIO_0 is configured to VDD, VDDIO_1 is configured to 3.3 V, and VDDIO_2 is configured to VADJ by placing the jumpers in the respective positions, as shown in Figure A-9.
Figure A-9. VDDIO Select
VDDIO_0=VDD(5 V/3.3 V)
A.1.6.2
VDDIO_1=3.3 V
VDDIO_2=VADJ
SW4 - Processor Reset Button
The board has a push button switch that resets the PSoC device attached to the processor module.
One side of the switch is tied to the XRES pin of the processor module socket. The other end of the
switch is tied to the HW_RESET pin of the processor module socket. This allows the module
designer to tie the HW_RESET line either high or low, depending on which direction the processor
reset is active.
Note PSoC 1 devices are active-high reset. Therefore, a light pull-down resistor may be necessary
on the XRES pin of designs with these devices to avoid unintentional device resets. PSoC 3 and
PSoC 5 devices are active-low reset. Therefore, a light pull-up resistor may be necessary on the
XRES pin of designs with these devices to avoid unintentional device resets.
A.1.6.3
U8 - External MHz Oscillator
The board supports the use of an external high frequency 8-pin PDIP oscillator. The speed of the
oscillator supported is dependent on the specifications of the PSoC device used. The output of this
oscillator is routed to P15[4] on receptacle P2 and TP62 near P2 of the DVK board.
A.1.6.4
P1, P2, P3, and P4 - Processor Module Receptacles
Processor modules provide modularity to this board. Sockets P1 to P4 are used to connect a processor module to the board. All supported GPIOs (including special I/Os), along with VDD DIG, VDD
ANLG, 5 V, 3.3 V, VBUS, and VBAT (only connected to a surface mount pad on the board) are connected to these receptacles. In addition, each of the VDDIO power pins are connected to these
receptacles. The full speed USB D+ and D– signals are also connected to one of the sockets. Processor reset is connected to P1. Any "no connect" pins are brought out to surface mount test pads.

A.2.6
Enabling Boost Component in PSoC 3 and PSoC 5 Processor Modules
To enable the boost convertor functionality, make the following hardware changes on the board.
■
Populate resistors R6, R7, R14, R15, R16, R17, and R38 with 0- resistors.
■
Ensure that R37 and R43 are removed.
The input power supply to the boost convertor must be provided through the Vbat. After making
these changes, you can make a boost convertor based design by making the appropriate configurations in the project.

MiniProg3 LEDs
MiniProg3 provides five indicator LEDs:
B.2
■
Upper Left - Busy: A red LED that lights when an operation (such as programming or debug) is in
progress.
■
Lower Left - Status: A green LED that lights when the device is enumerated on the USB bus and
flashes when the MiniProg3 receives USB traffic.
■
Upper Right - Target Power: A red LED that lights to indicate that the MiniProg3 is supplying
power to the target connectors. Note that it does not light when target power is detected but not
being supplied by MiniProg3.
■
Lower Right - Aux: A yellow LED reserved for future use.
■
Middle - No Label: A yellow LED that indicates the configuration state of the device. It flashes
briefly during the initial configuration of the device. If this LED lights solid, a configuration error
has occurred and MiniProg3 must be disconnected from the USB port and reconnected.
Programming in Power Cycle Mode
Do not perform power cycle mode programming with PSoC Programmer on the CY8CKIT-001. This
is due to the design of the CY8C38 family module. VTARG of the MiniProg3 is wired exclusively to
VDDIO1 of the chip on the module. For power cycle programming to work, VTARG needs to be
wired to VDDD.

B.4
Protection Circuitry
The Vtarg and I/O pins of the two interface connectors are protected from ESD events and momentary short circuits by a group of TVS (Transient Voltage Suppressor) diodes. These diodes provide a
15 KV ESD event protection for each pin, and will clamp the pin levels to a safe voltage in the event
of a short circuit. The Vtarg pins are protected by a shared, 5 V clamp device capable of shunting
350 W of transient power. Each I/O pin is similarly protected by a 5 V, 30 W device.
B.5
Level Translation
The design provides level translators that interfaces with any I/O voltage in the range of 1.2 V to
5.5 V without damage and function properly. There are two different level translators used in the
design.
204
CY8CKIT-001 PSoC Development Kit Guide, Doc. # 001-48651 Rev. *J
Appendix C. MiniProg3 Technical Description
The MiniProg3 is a protocol translation device. It enables PC host software to communicate through
high-speed USB to the target device to be programmed or debugged. This is shown in Figure C-1.
The device side communication protocol can be one of several standards, and can occur over either
of two connectors. Table C-1 lists the protocols that are supported by each connector. MiniProg3
enables communication with target devices using I/O voltage levels from 1.5 V to 5.5 V. In addition,
MiniProg3 can provide power to a simple target board, at one of four voltage levels.

MiniProg3 Technical Description
C.1
Interfaces
C.1.1
ISSP
In-System Serial Programming (ISSP) is a Cypress legacy interface used to program the PSoC 1
family of microcontrollers. MiniProg3 supports programming PSoC 1 devices through the 5-pin
connector only.
For more information about the ISSP interface, see the PSoC 1 Technical Reference Manual.
C.1.2
JTAG
The Joint Test Action Group (JTAG) standard interface is supported by many high end
microcontrollers, including the PSoC 3 and PSoC 5 families. This interface allows a daisy chain bus
of multiple JTAG devices. MiniProg3 supports programming and debugging PSoC 3 and PSoC 5
devices using JTAG, through the 10-pin connector only.
C.1.3
SWD/SWV
Recent ARM based devices have introduced a new serial debugging standard called Serial Wire
Debug (SWD). The PSoC 3 and PSoC 5 family implements this standard, which offers the same programming and debug functions as JTAG, except the boundary scan and daisy chain. SWD uses
fewer pins of the device than the JTAG standard. MiniProg3 supports programming and debugging
PSoC 3 and PSoC 5 devices, using SWD, through the 5-pin or 10-pin connector.
The Single Wire Viewer (SWV) interface, also introduced by ARM, is used for program and data
monitoring, where the firmware may output data in a method similar to 'printf' debugging on PCs,
using a single pin. MiniProg3 supports monitoring of PSoC 3 and PSoC 5 firmware, using SWV,
through the 10-pin connector and in conjunction with SWD only.
C.1.4
I2C™
A common serial interface standard is the Inter-IC Communication (I2C) standard by Philips. It is
mainly used for communication between microcontrollers and other ICs on the same board, but can
also be used for intersystem communications. MiniProg3 implements an I2C multimaster host
controller that allows the tool to exchange data with I2C enabled devices on the target board. For
example, this feature may be used to tune CapSense designs.
For more information on the PSoC 3 and PSoC 5 JTAG, SWD, SWV, and I2C interfaces, see the
PSoC 3 and PSoC 5 Technical Reference Manual. For more information on PSoC 1 interfaces, see
the PSoC 1 Technical Reference Manual.

CY8CKIT-001 PSoC Development Kit Guide, Doc. # 001-48651 Rev. *J
MiniProg3 Technical Description
C.2
Connectors
Warning: It is recommended that a keyed 10-pin or 5-pin connector be used on the target board
applications as programmer/debugger headers for the MiniProg3. The I/Os of the MiniProg3 have
very limited series protection against over current. Therefore, plugging the MiniProg3 into a programming/debugger header backwards can potentially damage the MiniProg3.
C.2.1
5-Pin Connector
The 5-pin connector is configured as a single row with a 100-mil pitch. It is designed to mate with a
Molex model 22-23-2051 (straight) or 22-05-3051 (right angle) male header, with key tab. The signal
assignment is shown in this figure.

10-Pin Connector
The 10-pin connector is configured as a dual row with a 50-mil pitch. It is used with a ribbon cable

are the Samtec FTSH-105-01-L-DV-K (surface mount) and the FTSH-105-01-L-D-K (through hole)
or similar available from other vendors. The signal assignment is shown in this figure.

Power
MiniProg3 requires a connection to the Vddio supply of the target device to set the voltage level used
for communication. This is required regardless of the communication protocol and the port selected.
One of the connectors' VTARG pins must be connected to the Vddio supply of the target device. For
PSoC 3 and PSoC 5, this is the Vddio1 supply, because this is the supply used to drive the debug
pins. Failing to connect VTARG, or connecting it to the wrong supply results in the MiniProg3 being
unable to communicate with the target device.
On boards where there is a single power supply for the entire board, the MiniProg3 can, in some
cases, supply power to the board. This supply is limited to approximately 200 mA and is protected
against excess current draw. The power supply voltage can be selected from one of 1.8 V, 2.5 V,
3.3 V, or 5 V. The 5-V supply may be as low as 4.25 V or as high as 5.5 V, as it is supplied directly
from the USB port.
