E. About the Cypress CY3640 USB Starter Kit
Overview
The Cypress CY3640 USB Start er Kit incl udes a fully functional USB thermometer devic e, a
Windows95 thermometer application, and a USB Thermometer device driver. Together, these
components allow the user to m easure and display temperatures between 0ºC and 70ºC to an
accuracy of ±1ºC.
In addition to bei ng a useful US B device, Cypress has designed t he US B S tarter Kit to serve as
an easily customizable platform for USB device development using the Cy pr ess CY7C63X0X
family of USB contr oller s.
Features
The CY3640 has the following features:
The Cypress USB Controller is socketed i n a 20- pin socket
It may be removed, reprogrammed, and replaced for easy development of new assembly
code.
Cypress has supplied a bread board ar ea ( sea of holes)
This area will accept wir e wrap pi ns and wire wrap sockets. This area will make it easy to
develop additi onal logic on-board.
A connector for use with standard 40-pin flat-cable connectors has been prov ided.
All signals fr om the Cypress USB Controller, which are useful for the developm ent of exter nal
logic, are available at pins on the connector. The signal names are label ed on the t op lay er of
the board. Pin numbers on the c onnec tor are labeled on both the top and bottom layers of the
board to make it easy to wire to the connec tor.
An identical set of signal vias is placed adjacent to the connector for easy wiri ng to the
signals.
Connections to ext er nal power source
There is a location f or an ext er nal power supply c onnec tor, but the connector is not suppli ed
with the kit. Indiv idual labeled locations for Vss, USB Vbus (the positive supply of the USB ),
and External Vcc are provided on either side of the sea of holes.
LED indicators (Power and Enumeration)
The CY3640 includes two LEDs: a red and a green one. A s conf igured when the CY3640 is
shipped from the f actor y, the LEDs are used to indicate that power is applied and that the
USB host has enumerated t he Cy pr ess USB Thermometer device, respectively.
The anode of each LED is connected to the USB Vbus (positive supply) through a current
limiting resistor . The cathode of each device is connected to three places to allow you to
reconfigure them for your own purposes: a j um per , a pin on the 40-pin connector, and a hole
for installi ng a wir e wrap pi n.
The Power LED
The Power LED (as shipped from Cypress) is used t o indicate that power (Vbus) from the
USB has been applied. It is connected through a jumper (JP1) and a current limiting resistor
(R4) directl y between Vbus and Vss, and will be lit whenever power is applied through the
USB. The user may remove JP1 if desired.

User’s Guide
The cathode of thi s LED is also connected to a pin on the 40- pin c onnec tor (pin 8) and to an
adjacent hol e that may be used to install a wire wrap pin. This allows the user to remove the
factory-installed jumper to Vss and use the LED for their own purposes.
Although it may be convenient to know when the USB i s appl yi ng power, dur ing
Note:
development. The f act that JP1 is left c onnec ted to Vss makes the dev ic e not strictly
compatible wit h the USB specification, because it will draw approxim ately 20 mA whenever it
is connected. T he USB specification limits power prior to the device being configured to 500
µA.
The Enumeration LED
The Enumeration LED ( as shipped f r om Cy pr ess) is used to i ndic ate that the USB
Thermometer dev ic e has been enumerated. The cathode of the LED is connected to P13
through a jumper (JP2) which controls its path to Vss.
The cathode of thi s LED is also connected to a pin on the 40- pin c onnec tor (pin 10) and to an
adjacent hol e that may be used to install a wire wrap pin. This allows the user to remove the
jumper to P13 and use the LED for their own purposes.
The switch (SW1)
SW1 (as shipped) on the Cypress USB Thermometer is used to select whether the
Thermometer Windows application displays the temperatur e in Centigrade or Fahrenheit. It is
a momentary SPST.
One pole of the switch is connected to Vss. The other pole is connected to Vcc (Vbus)
through R4, to a pin on the 40-pin connector (pin 6), to an adjacent hole that may be used for
installi ng a wire wrap pin, as well as to the GPIO P 12 of t he USB controller through a jumper
JP3. This allows the user to remove the jumper to P12 and use SW1 for their own purposes.
The breadboard area
Sea of holes
Cypress has provided an area that will ac c ept wire wrap pi ns and wire wrap sockets for
development of l ogic and functionality on the board.
USB Vbus (Vcc) and Vss connections
We have provided loc ations for connect ing power and ground from the USB to your bread
board area. These locations will ac c ept wire wrap pins.
External Vcc connect ions
If you need to power your breadboard with an external supply, a connector site (P 1) i s
supplied for t hat purpose. Two capacitor locations are also provi ded adjac ent to the
connector for by pass. C6 i s a bul k bypass and C7 is f or high frequenc y . These capacitors are
not populated wit h the CY3640 as shipped, and y ou shoul d use components appropriate to
your needs.
The External Vcc supply is brought to the bread board area and connected to three locations
labeled (oddly enough) Ext. Vcc. You may insert wire wrap pins in these locations to rout e to
your breadboard area.
The temperatur e sensor (U2)
The temperatur e sensor dev ic e is socketed so i t can be removed if you need to use the
associated pins on the Cy pr ess USB Contr oller for other logic on your breadboard.
Ferrite bead locati ons
If noise is a problem in your envir onm ent, locations for two ferrite beads (FB1 and FB2) have
been provided: one f or the V cc supply from the USB and one for the Ground return to the

USB. These beads should not be nec essarily and are provided for exceptional noisy
environments.
The locations are shorted by a trac e on the bottom layer of the PC board. If you desire to use
ferrite beads, you should c ut the traces and install beads suitable to your needs.
Other items of interest
Bulk capacit or bl eeder r esi stor ( R5)
A resistor is provided to bleed off t he c har ge stor ed on the bulk capacitor . This is provided to
insure that charge is removed fr om the bulk c apaci tor and hence the board logic, within a
short period aft er the devic e is unpl ugged from the USB.
USB connector
A “B” receptacl e has been provided on the board so a detachable A/B cable can be used with
the device.
A footprint for an in-li ne c onnec tor (P2) to a permanently attached USB cable has been
provided if you need to have a non- r em ov able US B cable.
