Note the following details of the code protection feature on Microchip devices:  
Microchip products meet the specification contained in their particular Microchip Data Sheet.  
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the  
intended manner and under normal conditions.  
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our  
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data  
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

2.5  
DEMO OPERATION  
The pre-programmed demo is used to demonstrate the basic operation of Microchip  
Remote Keyless Entry (RKE) solutions. The demo highlights capabilities of transmitting  
®
and receiving data that is secured over the air. Two different methods, KEELOQ Classic  
®
and KEELOQ AES, are used in this demo.  
2.5.1  
Key Fob as Transmitter  
The pre-programmed demonstration shows how to secure information during data  
transmission. Pressing any one of four buttons on the red key fob, the information  
about the pressed button will be encrypted and transmitted. When data is being  
transmitted, the LED on the key fob will flash. Two ways to secure the information have  
been shown in this demo: KEELOQ Classic and KEELOQ AES. When button 1 or 2 (see  
Figure 2-2) is pressed, the information is secured with KEELOQ Classic before the  
transmission; when button 3 or 4 (see Figure 2-2) is pressed, the information is secured  
with KEELOQ AES before the transmission.  
For details on KEELOQ Classic and KEELOQ AES, please refer to Microchip application  
®
notes AN1259, “KEELOQ Microcontroller-Based Code Hopping Encoder” and AN1265  
®
KEELOQ with AES Microcontroller-Based Code Hopping Encoder”.  
The key fob has four push buttons and is powered by a CR2032 coin battery. The key  
fob is shown in Figure 2-2, where the four buttons are labeled individually.

2.5.2  
Embedded Security Development Board as Receiver  
When the SX1239 Receiver PICtail Daughter Board receives a secured packet, the  
content of the packet is acquired by the target application microcontroller. Based on the  
length of the received packet, the target application microcontroller decides the cipher  
(KEELOQ Classic or KEELOQ AES) that is used to secure the data. The decryption  
process reveals the plain text, and the authentication process verifies whether the plain  
text is valid information.  
2.5.2.1  
KEELOQ CLASSIC  
For KEELOQ Classic, only a message from a known transmitter can be accepted by the  
receiver. If a packet is received from an unknown transmitter, the message “KLQ  
Transmitter Not Learned” will be displayed on the LCD, as shown in Figure 2-3.  
FIGURE 2-3:  
ERROR MESSAGE OF RECEIVING PACKET FROM  
UNKNOWN TRANSMITTER  
To learn a transmitter, the receiver initiates the learning process by pressing button  
SW4. The learning procedure will be started and the message “Learn mode active”  
will be displayed on the LCD, as shown in Figure 2-4.  
FIGURE 2-4:  
START LEARN MODE  
2012 Microchip Technology Inc.  
DS41646A-page 17  
Wireless Security Remote Control Development Kit User’s Guide  
In the event no KEELOQ Classic packet from an unknown transmitter is received within  
18 seconds, the KEELOQ Classic learn mode will time out and display the message  
Learn mode timeout” on the LCD, as shown in Figure 2-5.  
FIGURE 2-5:  
LEARN MODE TIMEOUT  
The known transmitters and their latest counters are stored in the Nonvolatile Memory  
(NVM) space of the microcontroller. When all slots in the NVM space for transmitters  
are taken, the learning process will fail. Pressing and holding button SW3 for a few  
seconds will erase all transmitter records from the NVM, and then the display message  
Memory Erased” on the LCD, as shown in Figure 2-6.  
FIGURE 2-6:  
ERASE TRANSMITTER RECORDS FROM MEMORY  
When a KEELOQ Classic packet is received from a known transmitter, the contents of  
the packet is displayed on the LCD, as shown in Figure 2-7. The following information  
from the KEELOQ Classic packet are available:  
• Encoder: KLQ that represents KEELOQ Classic  
• Serial number of the transmitter: 28-bit serial number (according to Figure 2-7) in  
this transmission  
• Counter: 16-bit number (according to Figure 2-7) in this transmission  
• Function Code: A bitmap of the pressed buttons (it will be 3 if both KLQ buttons  
are pressed), depending on the button pressed on the key fob  
FIGURE 2-7:  
KEELOQ PACKET INFORMATION  
DS41646A-page 18  
2012 Microchip Technology Inc.  
Getting Started  
2.5.2.2  
KEELOQ AES  
For KEELOQ AES, there is no requirement that a transmitter must be known to the  
receiver before a packet can be accepted, so there is no learning process for a packet  
that is encoded with KEELOQ AES cipher. When a KEELOQ AES packet is received, the  
contents of the packet is displayed on the LCD, as shown in Figure 2-8. The following  
information from the KEELOQ AES packet are available:  
• Encoder: AES that represents KEELOQ AES  
• Serial number of the transmitter: 32-bit serial number (according to Figure 2-8) in  
this transmission  
• Counter: 32-bit counter (according to Figure 2-8) in this transmission  
• Function Code: A bitmap of pressed buttons, depending on the button pressed on  
the key fob  
FIGURE 2-8:  
2.6  
EMBEDDED SECURITY DEVELOPMENT BOARD HARDWARE SELF-CHECK  
A hardware self-check can be performed to ensure the hardware integrity of the  
Embedded Security Development Board. The instruction of the hardware self-check is  
displayed on the LCD. The test result is either checked by firmware and display on the  
LCD, or verified by user observation.  
To initiate the hardware self-check, press and hold push button SW1 before powering  
up the Embedded Security Development Board. SW1 can then be released when  
HDW Self Tests” is displayed on the LCD screen. Four individual hardware self-tests  
will then be performed one by one.  
2.6.0.1  
BUTTON TESTS  
Button Test” will be displayed on the first line of the LCD display. Test instructions of  
pressing individual buttons will be displayed on the second line of the LCD display.  
Once a required push button is pressed, the test instruction message will be changed  
for the next push button. Once all push buttons have been tested, SW1 needs to be  
pressed to move forward to the LED test.  
2.6.0.2  
LED TESTS  
There are two sets, ten LEDs, which can be controlled by the host and target  
application microcontroller separately. When LED tests start, the message “LEDs  
Flashing” will be displayed on the first line of the LCD display. During the tests, two  
sets of LEDs will be flashing separately, while LEDs from the same set should be  
flashing together. The user should observe that all LEDs are turned on and off with  
flashing intervals of roughly one second. Once the user has verified the LED test, SW1  
needs to be pressed to move forward to the RTCC test.  
2012 Microchip Technology Inc.  
DS41646A-page 19  
Wireless Security Remote Control Development Kit User’s Guide  
2.6.0.3  
RTCC TEST  
When RTCC tests are initiated, the LCD display will show the clock and calendar. If no  
coin battery for RTCC has been installed, the time displayed will be close to the reset  
time of January 1, 2012. On the other hand, if a coin battery for RTCC is installed, the  
time displayed will be based on whatever is previously set, plus the time that has been  
passed. Observe that the clock is advancing. Once the RTCC test is done, SW1 needs  
to be pressed to move forward to the SPI test.  
2.6.0.4  
SPI TEST  
The SPI test in hardware self-check is performed to the SPI bus that connects the  
target application microcontroller and the SX1239 Receiver PICtail Daughter Board.  
Therefore, the SX1239 Receiver PICtail Daughter Board must have been plugged in  
before this test starts. Once the SPI test starts, the target application microcontroller  
requests specific information from the SX1239 receiver through the SPI bus. If the  
expected response is received, then the “Successful” status will be displayed;  
otherwise, the “Fail” status will be displayed.  
Note: If a PICtail daughter board other than the SX1239 Receiver PICtail  
Daughter Board is plugged into the PICtail connector, even though the SPI  
bus may still work, the SPI test might show failure status. The reason is due  
to the expected values to be received from the SX1239.

PRINTED CIRCUIT BOARD DESCRIPTION  
The key fob PCB is a two-layer, plated through hole, 0.031 inches (0.7874 millimeters)  
thick, FR4 material. Figure 3-2 shows the top layer of the PCB. All components, except  
the LED, are on the top layer. A PCB antenna is employed in the design for reduced  
cost and compactness. The PCB antenna is explained in more detail below.  
P1 is the ICSP™ programming port. See Chapter 6. “Developing with the Wireless  
Security Remote Control Development Kit” for suggestions on developing and  
programming the key fob.

PCB ANTENNA DESCRIPTION  
The PCB antenna is a combination of top and bottom PCB layer traces, as shown in  
Figure 3-4. The feed point from the transmitter is on the right side of the figure. It is a  
top layer trace shown in red. It taps into the PCB loop antenna on the bottom layer  
shown in blue. The antenna loops to the left side of the PCB and is terminated to ground  
by a capacitor.  
The PCB antenna is an “electrically small loop antenna.” That is, the wavelength of the  
antenna is very much less than the one-quarter wavelength that antennas are normally  
designed to. This type of antenna has an extremely high quality factor (Q). Therefore,  
it is very susceptible to parasitic impedances and very challenging to impedance match  
to the transmitter.

Figure 3-4 is a design suggestion. The designer is cautioned that even though this  
design can be copied, the final product will require tuning. There are many factors that  
determine the performance of a PCB antenna: thickness of the copper layer, thickness  
of the PCB material, choice of the PCB material (e.g., FR4), and choice of the passive  
components used in the impedance matching circuit. The PCB antenna dimensions are  
not critical. Once the design has been tuned, what is important is the consistency of the  
manufacture.

HARDWARE DESCRIPTION  
5.2.1  
Serial Communications Connections  
The Embedded Security Development Board is divided into two halves. The left side is  
the host controller half. The right side is the target application half. The two halves are  
connected by three wires labeled TP1, TP2, and TP3. Table 5-1 lists the respective  
microcontroller I/O port connections.

The host controller half is controlled by a PIC16LF1947 microcontroller. The  
PIC16LF1947 microcontroller communicates with a 16x2 character LCD display  
(LCD1), an MCP2200 USB to UART communications IC (U2), an MCP795W10 SPI  
Real-Time Clock Calendar IC (U5), four push button switches (SW5-SW8), and seven  
LEDs (D8-D14). The PIC16LF1947 microcontroller can be programmed/debugged via  
the ICSP™ header, J4. The host controller half schematic is shown in Appendix C as  
Figure C-2.  
The target application half has a PIC16LF1398 microcontroller. The PIC16LF1398  
microcontroller communicates with the 28-pin PICtail connector (J1), Serial Accessory  
Port (P20), four push button switches (SW1-SW4), and four LEDs (D4-D7). The  
PIC16LF1398 microcontroller can be programmed/debugged via the ICSP header, J5.  
The target application half schematic is shown in Appendix C as Figure C-3.  
5.2.2  
Serial Accessory Port (P20)  
The Serial Accessory Port provides a simple serial interface for the external modules.  
These modules may be either external sensor or accessory board. The partial list of  
Microchip boards with SAP capabilities includes the following:  
• LCD Serial Accessary Board  
• RS232 Serial Accessary Board  
For more information about the existing accessory boards, visit http://www.microchip.com  
or refer to the “RS-232 Serial Accessory Board User’s Guide” (DS70649).  
The following interfaces are supported by the Serial Accessory Port:  
• 3 or 4 wire SPI  
2
• I C™  
• USART  
The on-board switch “S1” selects these interfaces. Jumpers J7 and J8 pull-up resistors  
2
when I C is selected and the pull-up resistors are not available on the daughter board.  
Software modifications are expected to use those interfaces when pins are assigned  
different functionalities. For more information on the port pin assignment, see the  
schematic in Appendix C.  
5.2.3  
USB Interface Port  
Microchip MCP2200 provides USB to UART support. MCP2200 provides automatic  
conversion between UART and full-speed USB 2.0 communication. At the same time,  
the USB interface port can be used to power the Embedded Security Development  
Board directly. For more information, please refer to the Microchip MCP2200 data  
sheet.  
DS41646A-page 28

Embedded Security Development Board  
5.2.4  
PICtail Port  
The PICtail port is a 28-pin interface port that supports Microchip’s RF-based daughter  
cards. The PICtail port provides the following interfaces to the daughter cards:  
• Power Supply  
• SPI interface  
• Interrupt request lines  
• Other digital/analog I/O lines  
Note: The user must be careful about the PICtail port pins that share different  
functions of the board. The user needs to check the schematics before  
assigning functions for any port pin.  
There are many Microchip accessory daughter cards, which have PICtail port  
connectivity. When not used as one of the components in the Wireless Security Remote  
Control Development Kit, the Embedded Security Development Board can be  
connected with any daughter board with PICtail port, and perform different  
functionalities. Refer to the Microchip web site http://www.microchip.com for accessory  
daughter boards with PICtail port.  
5.2.5  
LCD Display  
The Embedded Security Development Board supports 16x2 character LCD display with  
backlight. The LCD is controlled by the host microcontroller through the SPI port. For  
details about the LCD display, refer to the data sheet of NHD-C0216CZ-FSW-FBW-3V3  
by Newhaven Display (http://www.newhavendisplay.com).  
5.2.6  
Real-Time Clock and Calendar (RTCC) Module  
The Embedded Security Development Board RTCC module can be used to set and  
track clock and calendar precisely. The RTCC functionality is achieved with the  
Microchip MCP795W10. The RTCC module is controlled by the host microcontroller  
through the SPI interface. The RTCC module can be powered either by the 3.3V power  
from the Embedded Security Development Board, or by a separate coin battery when  
external power is not available. For details on operating this RTCC module, refer to the  
data sheet of the MCP795W10 at http://www.microchip.com/MCP795W10.  
5.2.7  
Push Buttons  
The Embedded Security Development Board has two sets of push buttons. Each set  
consists of four individual push buttons and serves as input to the host and target  
application microcontrollers.  
The four push buttons for the target application microcontroller are read as a single  
analog input. Depending on the different ratios of pull-up and pull-down resister values,  
the input analog voltages to the master microcontroller are different. Therefore, through  
the ADC on the target application microcontroller, the button that is pressed can be  
identified. Such design is used to save I/O pin requirement for the target application  
microcontroller. The details of the push buttons design can be found in the schematics  
in Appendix C.  
The four push buttons for the host microcontroller are four separate digital inputs to the  
slave microcontroller, due to the abundant I/O pin availability for the slave  
microcontroller. All buttons are assigned to the individual interrupt lines of the  
microcontroller and are not driven by external pull-up circuitry to save power  
consumption. The user software must enable the PORTB pull-ups of the  
microcontroller before evaluating the button state.  
2012 Microchip Technology Inc.  
DS41646A-page 29  
Wireless Security Remote Control Development Kit User’s Guide  
The MCLR push button is connected to the RE3/MCLR pin of the target application  
microcontroller. The RE3/MCLR pin of the target application microcontroller is also one  
of the SPI lines that control the host microcontroller. When the target application and  
host microcontrollers are interconnected, the RE3/MCLR pin of target application  
microcontroller is configured to be a normal digital I/O pin; therefore, the MCLR push  
button is ineffective. Otherwise, if an SPI intercommunication is not required between  
the target application and host microcontroller, the pin can be configured as RESET  
and the MCLR button can be used.  
5.2.8  
LEDs  
There are two sets of LEDs that are controlled by the target application and host  
microcontrollers, respectively. The target application MCU controls a set of four LEDs  
through the digital output pins. The host MCU controls a set of six LEDs through digital  
output pins. The two sets of LEDs may be useful in the demo or debugging process.  
Two LEDs (D15, D16) on the left half are used to identify the TX and RX operation of  
MCP2200. They cannot be controlled by the target application or host microcontroller.  
Similarly, LED D2 indicates the power availability. This LED cannot be controlled either  
by the target application or the host microcontroller.  
5.2.9  
Power Supply  
The Embedded Security Development Board can be powered by one of the following  
two sources:  
• USB port  
• External 3.3V power source through GND and +VEXT connectors  
Jumper J6 is used to choose the power source. When the left side, pins 1-2 of J6, are  
closed, USB power is selected; when the right side, pins 2-3 of J6, are closed, external  
power source is selected.  
When the USB port is used to power the board, the input voltage is stabilized by  
Microchip MCP1703, 250 mA, 3.3V and low quiescent current LDO regulator U3.  
5.2.10 ICSP™ Programming/Debugging Ports  
There are two ICSP™ programming/debugging ports on the Embedded Security  
Development Board. The ICSP port J4 on the left is used to program the host  
microcontroller. The ICSP port J5 on the right is used to program the target application  
microcontroller. Figure 5-2 shows the ICSP ports.

Chapter 6. Developing with the Wireless Security Remote  
Control Development Kit  
6.1  
INTRODUCTION  
This chapter provides some suggestions regarding the development of an RKE  
solution on the Wireless Security Remote Control Development Kit. General design  
considerations are provided on both the transmitter and receiver side.  
6.2  
DEVELOPING WITH A KEY FOB AS TRANSMITTER  
To modify the hex code in the key fob, the developer needs to open the red plastic  
enclosure. The ICSP™ port is available on the key fob PCB as six contact areas. To  
program the PIC12LF1840T39A on the PCB, the developer needs to perform the  
following steps:  
• Remove the PCB board from the plastic enclosure and lay the PCB board on a  
nonconductive surface.  
• Align the six ICSP pins to the contact areas on the PCB. Push the ICSP pins to  
the contact areas and avoid any movement during programming. Figure 6-1  
shows how to program the key fob.  
• When testing the key fob transmission when the plastic enclosure is open, avoid  
touching any PCB area with your finger.  
Note: For simplicity, all key fobs in the demo share the same serial number.  
FIGURE 6-1:  
PROGRAMMING THE KEY FOB  
As a secured RKE system, KEELOQ security keys, especially the manufacturer key is  
essential to the security of the whole system. It is highly recommended to use  
®
code-protect of the PIC MCU memory.  
2012 Microchip Technology Inc.  
DS41646A-page 31  
Wireless Security Remote Control Development Kit User’s Guide  
The Microchip RKE demo uses PWM, driven by interrupt, in data whitening procedure.  
The transmission data rate over the air that can be achieved is tightly related to the  
operation speed of the microcontroller. Higher data rate requires faster processing  
speed. Higher transmission data rate may reduce the total active time for each  
transmission; however, higher microcontroller processing speed generally has more  
current consumption. The real application may need compromise between higher data  
rate and faster processing speed to get the optimal battery life.  
6.3  
DEVELOPING WITH THE EMBEDDED SECURITY DEVELOPMENT BOARD  
AS RECEIVER  
The Embedded Security Development Board acts as a receiver in the Wireless  
Security Remote Control Development Kit. The target application microcontroller on  
the right side of the development board is the driving host for the receiver. All data  
receiving and KEELOQ security functionalities are performed by the target application  
microcontroller. On the other hand, the host microcontroller is mainly used to drive the  
LCD display in this demo.  
If the developer decides to develop the application on the target application  
microcontroller only, intercommunication between the target application and host  
microcontrollers can be ignored. The prototyping area under the four push buttons for  
target application controller can be used to prototype the application.  
Same as the transmitter, when continuous mode is used to receive data, the data rate  
is tightly associated with the processing speed of the microcontroller. Unlike the  
transmitter, which is usually powered by battery, the receiving side usually is powered  
by mains power, and power consumption is of less concern. It is possible to run the  
microcontroller faster to compensate higher data rate.  
On the other hand, if the developer decides to use the host microcontroller too, then  
the intercommunication between the two microcontrollers may need attention. The host  
microcontroller is an SPI slave, and thus requires faster response to the SPI command.  
Generally speaking, if no SPI delay is applied by the target application controller side,  
the operation speed of the host microcontroller needs to be double that of the target  
application microcontroller.
