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.

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.

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:
2012 Microchip Technology Inc.
START LEARN MODE
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

KEELOQ PACKET INFORMATION
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:

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:
DS41646A-page 20
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.

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
I2C™
USART
The on-board switch “S1” selects these interfaces. Jumpers J7 and J8 pull-up resistors
when I2C 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.

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.
