Power Supply to Pod

The pod can have power supplied either by the ICE or by your system. Configure the project

debugger settings in PSoC Designer with the appropriate power supply setting. See PSoC

Designer documentation for information on setting power options for the debugger.

Using the enCoRe II Internal 3.3 Volt Regulator Output (VREG)

Some enCoRe II devices have a built-in 3.3-volt regulator that can be used to supply external

devices with regulated voltage. To use the regulator for external devices, a 1.0uF or larger

ceramic cap must be loaded close to the output pin. When using the pod, this capacitor must

be loaded on position C12 on the bottom side of the pod board. The capacitor footprint on the

board at C12 is a 0805 sized surface mount footprint. Note that this capacitor must not be

loaded if using the VREG pin (P1.2) on enCoRe II as a GPIO. Be sure that the external

circuitry does not consume more power than the enCoRe II VREG output can provide as

specified in the data sheet. Note that the Wireless enCoRe II does not have an internal

voltage regulator.

External Clock Use with Pods

Emulation is not supported when using an external clock source for the enCoRe II’s CPU

clock. Designs which need external clock inputs are advised to use the internal clock for

emulation, then switch to the external clock for final testing.

CY3655 Hardware User Guide

USB Port

The USB type-B connector allows a USB connection to a PC. The power pin of the connector

goes to a jumper (J5) labeled “VBUS PWR” to allow USB power to be disconnected from the

system for emulator based development. In addition the USB signals can be viewed with an

oscilloscope or logic analyzer at header J7. For best USB signal quality, remove the jumpers

on J8 and J9 that connect the PS/2 port.

PS/2 Port

The PS/2 connector allows a PS/2 connection to a PC using the supplied cable. The power

pin of the connector goes to a jumper (J13) labeled “PS/2 PWR” to allow PS/2 power to be

disconnected from the system for emulator based development. In addition the PS/2 signals

can be viewed with an oscilloscope or logic analyzer at header J7. The enCoRe II pins used

for PS/2 are normally P1.0 and P1.1, but the alternate pins P1.5 and P1.6 can be used by

moving the jumpers on J8 and J9 to the side labeled “ALT PS/2”.

Analyzer Headers

P1, P2, and P3 are 20-pin headers that are compatible with Agilent logic analyzer terminator

adapters. This feature allows for a quick and simple debugging connection.

Prototyping Area

An area on the board is available for user-customized prototyping. The through-hole area

contains 0.1” spaced holes appropriate for DIP devices. On each side of the through-hole area

there is a ground row and a power row. Each power row can be individually configured to use

either the board’s VCC or the VREG output from the enCoRe II. There is also a surface mount

prototype area that accepts either 0.050” pitch parts or 0.025” pitch parts. Holes on the

outside of the surface mount pads allow signals to easily be soldered from elsewhere on the

board. A single row of signals above the proto area allows enCoRe II signals to be wired to

the proto area. This row has all signal names in silkscreen by their respective holes on both

the top and bottom side of the board.

Pushbuttons and LEDs

Three pushbuttons and three LEDs are available on the board for general purpose use. The

following table shows the enCoRe II signal name relation to the pushbutton or LED and its

jumper.

Pushbutton or LED Jumper enCoRe II Signal Name

D1 LED J12 P0.5

D2 LED J17 P0.6

D3 LED J19 P1.3

S1 Pushbutton J11 P0.2

S2 Pushbutton J16 P0.3

S3 Pushbutton J18 P0.4

The jumpers can be used to isolate the LED or pushbutton from the enCoRe II if desired. Note

that the LEDs use the same power as the enCoRe II. Driving the enCoRe pin low illuminates

the LEDs, and pushbutton presses can be detected by making the appropriate enCoRe II pin

an input with the pull-up enabled and detecting a low level when the button is pressed. Also

note that the pushbutton inputs are connected to enCoRe II pins that can be configured as

external interrupt pins.

Suggestions for Connecting the Pod

The Applications board can be used in conjunction with PSoC Designer and a pod for

development using the ICE-Cube in-circuit emulator. To do this, place either the PDIP-40 or

PDIP-24 foot into the socket at U1 and attach the pod. Note that the PDIP-18 and PDIP-16

feet cannot be used on the Applications board as their pin-outs differ substantially from the

PDIP-24 foot.

External Crystal or Ceramic Resonator Use

An external crystal or ceramic resonator can be used with the PDIP-40 part if a custom

frequency or tighter tolerance frequency is needed. The footprint at Y1 on the board can be

loaded with an HC49 sized through-hole or surface-mount crystal. Optionally a two- or

three-pin ceramic resonator can be used in this position. When using a crystal or ceramic

resonator, the resistors R2 and R3 should be removed to isolate the clock signals from the rest

of the board. Positions C4 and C5 should be populated with the appropriate load capacitance

for enCoRe II and the chosen crystal or ceramic resonator. Note that three-pin ceramic

resonators with built-in load capacitors do not need external capacitors loaded. Refer to the

enCoRe II data sheet for details on crystal or ceramic resonator specifications. Note that the

24-pin enCoRe II device does not support external crystals or ceramic resonators.

CY3655 Hardware User Guide

Using the enCoRe II Internal 3.3 Volt Regulator Output (VREG)

The enCoRe II has a built-in 3.3-volt regulator that can be used to supply external devices with

regulated voltage. To use the regulator for external devices, a 1.0uF or larger ceramic cap

must be loaded close to the output pin. For 40-pin devices, load the capacitor on position C2.

For 24-pin devices load the capacitor on position C9. The capacitor footprints on the board at

C2 and C9 are 0805 sized surface mount footprints. In addition there is a larger footprint

available to add a tantalum or electrolytic capacitor at C1 if more capacitance is desired for

larger transients, although the ceramic capacitor must still be used at C2 or C9 even if C1 is

loaded. Note that these capacitors must not be loaded if using the VREG pin (P1.2) on

enCoRe II as a GPIO. Be sure that the external circuitry does not consume more power than

the enCoRe II VREG output can provide as specified in the data sheet. Note that some

enCoRe II devices and all Wireless enCoRe II devices do not have an internal 3.3v regulator.

Wireless enCoRe II Development using the Applications Board

The Applications board provides a useful platform for Wireless enCoRe II development. The

following is a list of items to keep in mind when using the Applications board for Wireless

enCoRe II development.

•External power can be easily connected to the board using the Vcc and GND headers.

•The Wireless enCoRe II Pod must be used for emulation with voltages below 4 volts.

•The prototyping area of the board can be used to attach radio modules or other

components.

•Be aware of voltage restraints when using in-circuit programming. The ICE-Cube

powers the target at 3.3 volts when programming. The MiniProg powers the target at 5

volts when programming. Make sure any extra circuitry on the target board can

withstand the programming voltage.

In-circuit Programming on the Applications Board

enCoRe II devices and Wireless enCoRe II devices can be programmed while on the

Applications board using the ICE-Cube. Follow the programming steps below:

1. Using a USB cable plug the ICE-Cube into a PC that has the PSoC Programmer

application installed. Make sure the ICE-Cube is powered on.

2. Connect the yellow ISSP cable to the ICE-Cube through the RJ45 adapter. Note: Do

not use a black ISSP cable as it does not properly support enCoRe II or Wireless

enCoRe II.

3. Place the 5-pin end of the ISSP cable on the 5-pin header (J2) of the Applications

board. It will only go on in one orientation.

4. Make sure no external power supply is connected to Vcc or GND on the Applications

board. Make sure that a USB cable is not connected to connector J6. Make sure that a

PS/2 cable is not connected to connector J10. Note that the programming is done over

Page 8 of 16

CY3655 Hardware User Guide

the P1.0 and P1.1 pins, so any extra circuitry connected to those pins could affect

programming success. Also note that the programming from ICE-Cube is done with

ICE-Cube supplying 3.3 volts to the target system, so make sure any connected devices

can tolerate that voltage. The ICE-Cube is limited to properly supplying a maximum of

250 mA to the target circuit during programming.

5. Launch the PSoC Programmer application.

6. In the programming application, select the Port as the ICE-Cube by choosing

“USB/xxxxCxxx” where the “x” is specific to the USB device ID of your ICE-Cube. Most

likely, the ICE-Cube will be the only device in the list that is not an LPT port.

7. First select the appropriate device family then select the device to be programmed.

8. Load the programming file using the “File Load” button.

9. Program.

enCoRe II devices and Wireless enCoRe II devices can be programmed while on the

Applications board using the MiniProg (sold separately). Follow the programming steps below:

1. Using a USB cable, plug the MiniProg programmer into a PC that has the PSoC

Programmer application installed.

2. Place the MiniProg programmer on the 5-pin header (J2) of the Applications board. It

will only attach in one orientation. Note that there may be slight mechanical interference

with the MiniProg from the J9 header, but it will still work properly.

3. Make sure no external power supply is connected to Vcc or GND on the Applications

board. Make sure there is not a USB cable connected to connector J6. Make sure

there is not a PS/2 cable connected to connector J10. Note that the programming is

done over the P1.0 and P1.1 pins, so any extra circuitry connected to those pins could

affect programming success. Also note that the programming from MiniProg is done

with MiniProg supplying 5 volts to the target system, so make sure any connected

devices can tolerate that voltage. The MiniProg is limited to properly supplying a

maximum of 100 mA to the target circuit during programming.

4. Launch the PSoC Programmer application.

5. In the programming application, select the Port as the MiniProg. After selecting the

MiniProg, make sure that in the “Results” column of the window, an unexpected

firmware version was not found. If necessary, update the MiniProg’s firmware by

choosing “Upgrade Firmware” in the “Utilities” menu.

6. First select the appropriate device family then select the device to be programmed.

7. Load the programming file using the “File Load” button.

8. Program.
