Introduction of the TME Board
Thermal management is the combination of temperature sensing, fan control and the algorithms to
provide critical and optimized cooling to conserve power and reduce acoustic noise while
maintaining appropriate system temperatures. Typical solutions include the interaction with many
forms of both digital and analog temperature sensors. A thermal management solution must be able
to interact with a variety of I2C- or PWM-based digital or thermistor, diode-based or other analog
temperature sensors. Additionally, when controlling the active cooling elements in a system,
typically fans, the thermal management solution must be able to drive many independent control
signals to those elements based on internal algorithms.
The PSoC® 3 architecture enables a flexible and unique method of thermal management all in a
single chip combining the analog sensing capabilities, multiple I2C bus interfaces to sensors and
unique CPLD-like closed- or open-loop fan control capabilities with a built-in MCU available to
run the optimization algorithms for the cooling elements based on system temperature sensors.
The PSoC Thermal Management Expansion Board Kit (EBK) is a part of the PSoC development kit
ecosystem and is designed to work with the CY8CKIT-001 PSoC Development Kit (DVK) and
CY8CKIT-030 PSoC 3 Development Kit (DVK). It enables you to evaluate a system’s thermal
management functions and capabilities of PSoC 3 devices. You can evaluate the example projects
described in this guide or design and customize your own thermal management solution using
components in Cypress’s PSoC CreatorTM software (included in this kit) or by altering example
projects provided with this kit.
The PSoC Thermal Management EBK is used with the PSoC family of devices and is specifically
designed and packaged for use with the PSoC 3 device family. PSoC 3 is a programmable
system-on-chip platform for 8-, 16- and 32-bit applications. It combines precision analog and digital
logic with a high-performance, single-cycle on average, 67 MHz 8051 processor. With the
flexibility of the PSoC architecture, you can easily create your own custom thermal management
solution on chip with the exact functionality you need, in the way you want it – no more, no less.
This kit contains a thermal management expansion board and requires a Cypress host development
board in order to use it. As a part of the PSoC development kit ecosystem, it works with the
CY8CKIT-001 and CY8CKIT-030 kits.
The TME not only delivers the hardware required for system level integration, but is also
accompanied by a set of full source demonstrations illustrating the usage of on-board chip and
guidelines for designing custom specific applications.

2.2 Block Diagram of the TME Board Block Diagram of the TME Board
Figure 2-3 shows a functional diagram of the PSoC Thermal Management solution. This solution
enables control of up to 16 4-wire fans through CPU based firmware control (open-loop), hardware
control (closed-loop) all as a function of system temperatures (f(T)), all on a single chip. Digital
(1-wire, I2C, PWM) and analog temperature sensors (diode) can be interfaced to the PSoC using
configurable and customizable component modules.
Speed (Tachometer) signals from up to 16 fans are interpreted by the PSoC. In the open loop mode,
fan control can be configured by the firmware running on the PSoC (with CPU intervention). The
firmware synchronizes to hardware using end-of-cycle (eoc) pulses. Fan Drive signals are generated
by individual hardware PWMs on the PSoC (no banks) to drive the 4 wire fans. In the closed loop
mode, speed control is implemented entirely in hardware (no CPU intervention whatsoever). Fan
stall and speed regulation alerts are monitored in hardware. When implemented using a temperature
controlled algorithm, the temperatures are aggregated using a customizable function and then, in
turn, are the inputs to the fan-speed control algorithms. This implementation can also be
implemented in such a way that the relationships between the temperature sensors and specific fans
in the systems create physical thermal zones, which may utilize different algorithms for both
temperature sensor aggregation as well as fan-speed control to provide the optimal cooling in the
respective zones.
To enable thermal monitoring, custom PSoC components used to interface with different analog and
digital sensors are provided. This is explained in Section 4 of this User’s Manual. For analog
sensors, PSoC also provides on-board filtering, multiplexing and a 0.1% accurate internal voltage

reference for high resolution and highly accurate temperature sensor interface. PSoC 3 and PSoC 5
devices also include non-volatile EEPROM memory used in thermal solutions for event logging and
run-time system configuration storage. Communication with a host Board Management Controller
can be achieved via I2C, SMBus, PMBus or a variety of other communications protocols
implemented with easy-to-use PSoC Creator component blocks. In addition, external GPIO’s are
available on the PSoC devices for custom use.
Figure 2-3 Block Diagram of TME Board
Figure 2-4 shows the block diagram of the PSoC Thermal Management EBK. This kit demonstrates
control of up-to four 4-wire fans through firmware control (open-loop), hardware control (closed
loop) and as a function of system temperature – f(T). Two fans are mounted on the EBK. The
demonstration projects included with this kit show all three modes of fan control.
A 40-pin connector is provided on the EBK to route the input/output signals for thermal
management control to the PSoC on the host development board (such as the CY8CKIT-001 or
CY8CKIT-030). This connector carries power, fan PWM control and tachometer data lines, analog
and digital temperature sensor signals. SMBus alert, serial data and serial clock lines are also routed
from the host PSoC to a header on the expansion board. This will enable you to interface to the
EBK and receive alert and status information about the system.
