Safety Information
®
The CY8CKIT-036 PSoC 1 Thermal Management Expansion Board Kit is intended for use as a development platform for
hardware or software in a laboratory environment. The board is an open system design, which does not include a shielded
enclosure. For this reason, the board may cause interference with other electrical or electronic devices in close proximity. In
a domestic environment, this product may cause radio interference. In such cases, the user may be required to take
adequate preventive measures. Also, this board should not be used near any medical equipment or RF devices.
Attaching additional wiring to this product or modifying the product operation from the factory default may affect its
performance and cause interference with other apparatus in the immediate vicinity. If such interference is detected, suitable
mitigating measures should be taken.
The CY8CKIT-036 PSoC 1 Thermal Management Expansion Board Kit contains electrostatic
discharge (ESD) sensitive devices. Electrostatic charges readily accumulate on the human body
and any equipment, and can discharge without detection. Permanent damage may occur to devices
subjected to high-energy discharges. Proper ESD precautions are recommended to avoid
performance degradation or loss of functionality. Store unused CY8CKIT-036 boards in the
protective shipping package.
End-of-Life/Product Recycling
The end of life for this kit is five years from the date of manufacture mentioned on the back of the
box. Contact your nearest recycler to discard the kit.

General Safety Instructions
Electrostatic Discharge (ESD) Protection
ESD can damage boards and associated components. Cypress recommends that you perform procedures only at an ESD
workstation. If an ESD workstation is not available, use appropriate ESD protection by wearing an antistatic wrist strap
attached to the chassis ground (any unpainted metal surface) on your board when handling parts.
Handling Boards
CY8CKIT-036 PSoC 1 Thermal Management Kit boards are sensitive to ESD. Hold the board only by its edges. After
removing the board from its box, place it on a grounded, static-free surface. Use a conductive foam pad if available. Do not
slide the board over any surface.
Working with the Fans
Some fans run at very high rotational speeds (30,000 revolutions per minute or RPM) and the motors can provide significant
torque. The blades on this type of fan are often deeply angled and large enough for a finger to penetrate. This can cause a
lot of pain if the finger accidentally comes into contact with the fan blade.
Under no circumstances should the user attempt to stop or slow the fan using a finger or any other object. To test the PSoC
ability to detect and react to fan speed changes, airflow can be modulated by forcing air into the fan (either the input or the
output) using an air gun, another fan, or some other appropriate means.
The safest way to test PSoC’s ability to detect fan stall events (no rotation) is to disconnect the tachometer feedback by
removing either the tachometer wire, or the power to the fan, or by disconnecting the fan altogether.

1. Introduction
Thank you for your interest in the CY8CKIT-036 Thermal Management Expansion Board Kit (PSoC TM EBK). Thermal
management is a critical, system-level function, which ensures that all components in the system operate within safe
temperature limits. At the same time, it minimizes power consumption and acoustic noise.
Thermal management systems are complex, often requiring customized solutions with multiple temperature sensor types
and different numbers of fans.
The PSoC 1 TM EBK enables you to evaluate PSoC 1 as a single-chip system solution. The example project demonstrates
2
how PSoC 1 interfaces with three types of digital temperature sensors (I C based, pulse width modulator based, and 1-wire)
and a diode temperature sensor. The diode temperature sensor is simulated using a potentiometer. The project implements
two thermal zones, each with a brushless DC (BLDC) fan and two temperature sensors. The speed of each BLDC fan is
controlled based on the composite temperature (the weighted average of two temperature sensors) readings of their
respective zones.
The PSoC TM EBK requires the CY8CKIT-001 PSoC Development Kit (DVK) with the CY8CKIT-020 PSoC CY8C28 Family
Processor Module Kit.

4. Hardware
Board Details
This section provides an overview of the PSoC TM EBK hardware. The PSoC TM EBK contains two 4-wire, 12-V brushless
DC fans with connectors to support an additional two fans for designers who need to prototype with their own specific fan
models. Six temperature sensors (four different kinds) are also installed on the kit:
2




One TMP175 I C digital temperature sensor
Two TMP05 PWM temperature sensors
One DS18S20 1-wire digital temperature sensor
Two MMBT3094 temperature diodes
This combination of hardware elements enables you to rapidly prototype thermal management solutions in a variety of
configurations.
2
The PSoC TM EBK also provides an I C/SMBus/PMBus-compatible header to support systems that have a requirement for
communication with a host controller. All of this functionality is implemented on a single PSoC 1. The PSoC TM EBK routes
all the input and output signals for thermal management to a PSoC 1 mounted on a development kit platform such as the
CY8CKIT-001. PSoC 1 is not mounted on the PSoC TM EBK.
Figure 10 shows PSoC TM EBK hardware components. Kit enables you to control up to four 4-wire fans using MCU-based
control. Independent hardware PWM blocks in PSoC 1 generate fan drive signals to drive the 4-wire fans. PSoC 1 interprets
tachometer signals from the fans to determine fan rotational speeds. The firmware running on PSoC 1 achieves speed
control to the desired RPM. The firmware also detects fan stall or rotor lock faults.
2
To support digital sensor temperature sensing, standard PSoC 1 interfaces are used where possible (such as I C); PSoC
user modules have been developed for nontypical digital temperature sensors such as the PWM temperature sensor
(TMP05) and the 1-wire temperature sensor. For analog sensors, PSoC 1 also provides onboard filtering, multiplexing for
better resolution, and accurate temperature sensor measurement.
The example project provided with the PSoC TM EBK illustrates how to aggregate temperature sensor readings using a
variety of methods. The resultant “zone temperature” is used to set individual fan speeds. This is defined as a “thermal
zone.” The example project shows how you can configure each fan to be dependent on any of the available temperature
sensors in any combination. It also demonstrates how you can use the composite zone temperature to determine the
required fan speed to achieve system cooling needs.
Although not included in the example project, PSoC 1 devices also include nonvolatile EEPROM memory that you can use
to store sensor calibration information or for event and fault logging purposes. Communication with a host controller or
2
management processor can be achieved via I C, SMBus, PMBus, or a variety of other communications protocols
implemented with easy-to-use PSoC 1 user modules.
Note that PSoC TM EBK hardware limits support to a maximum of four fans. You can easily extend the PSoC 1 Thermal
Management solution to support up to 10 fans in a single device. Contact Cypress for further information on the full PSoC 1
Thermal Management solution.

PWM Temperature Sensors
The TMP05 PWM output digital temperature sensor is a monolithic temperature sensor that generates a modulated serial
digital output (PWM) signal. The duty cycle of this PWM signal is proportional to the ambient temperature measured by the
device. The high period (TH) of the PWM remains generally static over all temperatures, while the low period (TL) varies.
The ratio of TH/TL provides a method for determining the temperature according to the formula, temperature (°C) = 421 –
(751 × TH/TL). The TMP05 sensors have a 2-pin interface; a CONV/IN input that when pulsed by PSoC, initiates a new
temperature measurement; and an OUT output, which provides a PWM signal that you can decode using the temperature
formula to determine ambient temperature. The TMP05 sensors support a daisy-chain mode of operation, where the OUT
signal of the first sensor can be directly connected to the CONV/IN input of the subsequent sensor. The OUT of the second
sensor carries the PWM signals from both sensors. Many sensors can be daisy-chained in this fashion, with the final OUT
signal carrying the PWM temperature encoding from all sensors in the daisy chain. This sensor is generally operated in
either the one-shot mode or continuous mode.
For more details, refer to the TMP05 device datasheet, which is available on the device manufacturer's website or under the
datasheet folder at the installation location. Application note AN78737 – PSoC 1 – Temperature Sensing Solution using a
TMP05/TMP06 Digital Temperature Sensor discusses details about the digital temperature sensor and the implementation
in PSoC 1 with an example project.

PSOC TM EBK demonstrates an I C temperature sensing capability using a 2-wire I C compatible digital temperature
2
sensor, the TMP175. I C digital temperature sensors are common sensors for thermal management and are used in a
variety of communication, computer, consumer, environmental, industrial, and instrumentation applications due to the
2
popularity of the I C bus. For more details, refer to its datasheet, which is available on the manufacturer's website or under
the datasheet folder at the installation location. Application note AN2163 – Interfacing to 1-Wire/Two-Wire Digital
Temperature Sensors using PSoC 1 discusses details about the digital temperature sensor and the implementation in
PSoC 1 with an example project.
1-Wire Digital Temperature Sensors
PSOC TM EBK has a Maxim DS18S20 1-wire high-precision digital temperature sensor installed. The DS18S20 digital
thermometer provides 9-bit resolution Celsius temperature measurements and has an alarm function with nonvolatile userprogrammable upper and lower trigger points. The DS18S20 communicates over a proprietary 1-wire bus that by definition
requires only one data line (and ground) to communicate with a host microprocessor. It has an operating temperature range
of –55 °C to +125 °C. For more details, refer to its datasheet, which is available on the manufacturer's website or under the
datasheet folder at the installation location. Application note AN2163 – Interfacing to 1-Wire/Two-Wire Digital Temperature
Sensors using PSoC 1 discusses details about the digital temperature sensor and the implementation in PSoC 1 with an
example project.
Diode Analog Temperature Sensors
MMBT3904 is a bipolar junction transistor (BJT) designed as a general-purpose amplifier and switch. The useful dynamic
range extends to 100 mA as a switch and to 100 MHz as an amplifier. You can use the delta Vbe method described in
application note AN78920 – PSoC 1 Temperature Measurement Using Diode with PSOC TM EBK; the application note
discusses the operation theory and relevant mathematical equations. The implementation is primarily driven by firmware
due to the complexities associated with varying the source current fed to the BJT, filtering the ADC measurements, and
calibrating the analog subsystem, all of which are required to achieve sufficiently high accuracy with these low-cost
temperature sensors.
4-Wire Fan Connectors
The PSOC TM EBK provides four industry-standard 4-wire fan interface connectors and two AVC 12-V brushless DC fans.
For the fans that are mounted on the EBK,speeds are controllable up to 12,700 RPM via PWM control, with tachometer
output to calculate actual fan speeds. For more details, refer to its datasheet, which is available on the manufacturer's
website or under the datasheet folder at the installation location.

5. Example Project
The example project is available at <Install_Directory>\Cypress\PSoC 1 Thermal Management EBK\1.0\firmware.
Note: The default installation location is C:\Program Files\Cypress\PSoC 1 Thermal Management EBK\1.0 for 32-bit
machines and C:\Program Files(x86)\Cypress\PSoC 1 Thermal Management EBK\1.0 for 64-bit machines.
Overview
This example project demonstrates how the temperature sensors combined with the fans on the PSOC TM EBK can create
a complete thermal management system. The example shows how to combine temperature readings from a number of
temperature sensors in a variety of ways and use the composite temperature to set desired fan speeds according to a
customized transfer function.
The thermal management example project uses the concept of a “thermal zone.” A thermal zone describes the following:


How to combine multiple temperature sensor readings to form a composite zone temperature
How to map the zone temperature to a fan speed.
By this definition, each fan will be controlled according to its own independent thermal zone. This example has two thermal
TM
zones because PSOC EBK has only two fans installed. Algorithms currently implemented to combine multiple
temperature sensors into a composite zone temperature include straight average, weighted average, and maximum.
Straight average algorithm returns the average value of all the sensors used in that particular zone. Weighted average
algorithm first applies the weight to each sensor temperature as defined in the zone configuration and then takes the
average of the resultant number. Maximum algorithm simply returns the maximum temperature from sensors in that
particular zone. Algorithm for a particular zone can be selected by changing the zone configuration.
This example project uses the weighted method on both fans. A zone temperature to fan speed transfer function is then
definable for each zone. In this project, the transfer function used is table driven on both fans; that is, a lookup table maps
composite zone temperature to fan speed.

This example is a simulation of a thermal management system. The first zone, Zone 1, combines temperature
measurements from two temperature sensors (one analog and one digital). The analog sensor is simulated using a variable
potentiometer to allow easy demonstration of fan control over a wide simulated temperature range without the need for an
environmental chamber to cycle through temperatures. In Zone 1, the temperature sensors are combined using a weighted

average, where the potentiometer is given a 90% weight and the I C digital temperature sensor (U1 on PSOC TM EBK) is
given a 10% weight. You can adjust the potentiometer (R20 on the CY8CKIT-001 DVK) to vary the simulated temperature
value. The Zone 1 speed transfer function is table driven and follows the profile shown in Table 6. When temperature
increases, temperature vs speed will be as shown in Table 6. However, when temperature decreases, speed will decrease
only when temperature change is more than hysteresis. For example, when temperature is decreasing, speed will change
at 30 degree if current temperature is 35 degree or above. This is due to the reason that hysteresis is set to 4 for zone 1.

Zone 2 consists of two temperature sensors and a single fan. The Zone 2 speed transfer function is table driven and is
shown in Table 7. Note that the temperature range is narrow and close to room temperature. This is to allow for simple
testing at room temperature by just touching a temperature sensor with a warm finger to cause a fan speed change. In Zone
2, the temperature sensors are combined using a weighted average, where the 1-wire temperature sensor (U2 on PSOC
TM EBK) is given a 90% of the weight. The PWM temperature sensor (U3 on PSOC TM EBK) is given a 10% weight. In this
example, U2’s temperature reading will dominate the overall zone temperature calculation.
When temperature increases, temperature vs speed will be as shown in Table 7. However, when temperature
decreases, speed will decrease only when temperature change is more than hysteresis. For example, when
temperature is decreasing, speed will change at 25 degree if current temperature is 27 degree or above. This is
due to the reason that hysteresis is set to 1 for zone 2.

Firmware Structure
The Thermal Management System example consists of dedicated .c and .h files for every function (see Figure 23). You can
remove any function you do not need by removing the associated .c and .h file. The main application is responsible for the
user interface and for periodically calling the thermal manager. The application implementation can be found in main.c. The
thermal manager implementation can be found in ThermalManager.
The main application needs to call ThermalManager_Start() only to initialize the thermal manager, and then it must
periodically call ThermalManager_Service() and then call LCD_Menu() to run temperature and speed updates.
All the parameters that define the zone composite temperature sensor algorithm and the zone temperature to fan speed
algorithm are defined at the top of thermalmanager.c. To modify these settings, refer to thermalmanager.h for the relevant
keywords
Figure 23. Workspace Explorer
The entries in Table 6 and Table 7 are defined in the highlighted boxes in Figure 24. You can change temperature versus
fan speed entries based on design requirements.

Figure 24. Zone Temperature Versus Fan Speed Lookup Table
You can also change the key zone configuration parameters shown in Figure 25 based on design requirements. In this
figure, the red highlighted box shows where the weights for different temperature sensors are entered. See Table 5 for
details.
The blue highlighted box shows where the hysteresis for both the zones is set. Hysteresis has been defined to avoid
unnecessary fan speed changes in the temperature borders of the lookup table. For example, if the Zone 1 temperature
varies between 34.9 °C and 35.1 °C, the fan speed will be fluctuating between 5,500 and 6,500 RPM. To avoid this,
hysteresis logic is implemented in the firmware. In this case, it is defined as “4,” which means that if the temperature
changes from 34.9 °C to 35 °C, the fan speed will change from 5,500 to 6,500 RPM, but if the temperature again falls from
35 °C, the fan speed will not change until 31 °C to avoid unnecessary speed fluctuations in the border. You can change this
entry according to design requirements.
