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.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

2.1
INTRODUCTION
The MCS3142 Dual KEELOQ Encoder Wireless Remote Control Development Kit uses
an identical receiver module and demo board as seen in the Wireless Security Remote
Control Development Kit User’s Guide.
(http://ww1.microchip.com/downloads/en/DeviceDoc/41646A.pdf). This chapter will
explain how to setup the board and show the general operation.
2.2
USING THE STAND-ALONE DEMO
2.2.1
Setup
There are only a few steps to perform to get the stand-alone demo working:
1. Open the plastic enclosure of the red key fob by carefully prying apart the two
halves with a flat-head screw driver. Observe the correct battery polarity and
insert the coin battery into the holder. Put the key fob back together.
2. To verify that the key fob is properly installed, press any button and the LED
should flash when a button is pressed.
3. Plug in the RF receiver daughter board on the PICtail slot of the demo board.

2.2.2
Operation
The pre-programmed demo is used to demonstrate the operation of Microchip Remote
Keyless Entry (RKE) solutions. The demo highlights the capabilities of transmitting and
receiving secured data wirelessly. Two different methods, Classic KEELOQ and Ultimate
KEELOQ, are used in this demo.
The pre-programmed demonstration shows how to secure information during data
transmission.The transmitter sends out two types of packets. A Typical packet contains
the device serial number, button code, synchronization counter, timer (Ultimate
KEELOQ only) and various other parameters used in the decryption and validation
process. A Seed packet contains special data related to the encoder’s encryption key.
A Seed packet is sent infrequently, and only used when pairing a transmitter to a
receiver.
FIGURE 2-2:
MCS3142 KEY FOB
Pressing any one of the four buttons on the red key fob will start the encryption process
and eventual transmission of a KEELOQ packet. The LED will flash momentarily to
indicate a transmission.Table 2-1 describes the transmitter buttons and their functions.

The kit is configured to use the Secure Learn pairing mechanism. This requires the
encoders to transmit a special packet, called a Seed packet, with special information
the receiver needs to properly decrypt transmissions. This kit is configured to transmit
a Seed transmission with both buttons assigned to a particular encoder are pressed.
The pairing phase also requires a Typical transmission to complete the pairing process.

 2014 Microchip Technology Inc.
Quick Start
To pair a transmitter to the receiver using Secure learn:
1. Press SW3, the Secure Learn button on the Embedded Security Development
Board to enable Secure Learn mode.
2. If learning the Classic KEELOQ encoder, press both buttons 1 and 2. If learning
the Ultimate KEELOQ encoder, press both buttons 3 and 4. This will cause the
special Seed packet to be sent.
3. The receiver will indicate reception of the Seed transmission.
4. If learning the Ultimate KEELOQ encoder, press either button 3 or 4 to send a
Typical transmission.
5. The receiver will indicate successful pairing.
The kit also includes the SX1239 Receiver PICtail Daughter Board. It houses the
Semtech SX1239 wideband receiver. The target application configured the receiver on
start-up.
2.3
KEELOQ SCREENS
This section describes all of the LCD screens when used with the MCS3142
transmitter.
Note:
The receiver will always display the encoder serial number associated with
a transmission, regardless of the transmitter’s status with the receiver.
Only a message from a paired transmitter can be accepted by the receiver. If a packet
is received from an unknown transmitter, the message ‘Not Learned’ will be
displayed on the LCD, as shown in Figure 2-3 and Figure 2-4. The type of transmission
and the transmitter’s serial number are also displayed on the screen.

Chapter 3. Hardware Self-Test
3.1
INTRODUCTION
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 displayed 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.
3.2
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.
3.3
LED TESTS
There are two sets of LEDs. When the LED tests start, the message “LEDs Flashing”
will be displayed on the first line of the LCD display. During the tests, two sets four LEDs
(D4-D7) and seven LEDs (D8-D14) will flash in a pattern. 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.
3.4
RTCC TEST
When RTCC tests are initiated, the LCD display will show the clock and calendar. If no
coin battery for the RTCC has been installed, the time displayed will be close to the
reset time of January the 1st, 2012. If a coin battery for RTCC is installed, the time
displayed will be based on whatever was previously set, plus the time that has 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.
 2014 Microchip Technology Inc.
DS40001746A-page 18
Hardware Self-Test
3.5
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 appear; otherwise,
the “Fail” status will be displayed.
Note:
 2014 Microchip Technology Inc.
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 be working), the SPI test might show failure status. The demo
board expects an SX1239 to be identified on the SPI interface.

The host side 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 and debugged via
the ICSP™ header (J4).
The target application half has a PIC16LF1938 microcontroller. The PIC16LF1938
microcontroller communicates with the 28-pin PICtail connector (J1), the Serial
Accessory Port (P20), four push button switches (SW1-SW4), and four LEDs (D4-D7).
The PIC16LF1938 microcontroller can be programmed/debugged via the ICSP (J5).
The Embedded Security Development Board schematic is shown in Appendix
C. “Embedded Security Development Board Schematics” as Figure C-2.
5.3
SERIAL ACCESSORY PORT (P20)
The Serial Accessory Port provides a simple serial interface for the external modules.
These modules may be either an external sensor or an accessory board. The partial
list of Microchip boards with SAP capabilities includes the following:
• LCD Serial Accessory Board
• RS-232 Serial Accessory 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
Jumpers J7 and J8 connect pull-up resistors, typically useful when I2C is selected and
the pull-up resistors are not available on the daughter board.

USB INTERFACE PORT
The Microchip MCP2200 provides USB to UART support. The USB interface port can
also be used to power the Embedded Security Development Board directly. Please see
Section 8.2 “Installation” for more information about connecting the board to a PC.
5.5
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 the PICtail port, and perform different
functionalities. Refer to the Microchip web site http://www.microchip.com for accessory
daughter boards with PICtail port.
5.6
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.
5.7
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 is commonly used with Ultimate KEELOQ, which
relies on the system clock as part of its security.
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.

5.8
PUSH BUTTONS
The Embedded Security Development Board has two sets of push buttons. SW1-SW4
on the target application side and SW5 on the host controller side.
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 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.
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 I2C 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.
5.9
LEDS
There are two sets of LEDs that are controlled by the target application and the 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.
LEDs D15 and D16 on the left half are used to identify the TX and RX operation of
MCP2200. The default configuration of the MCP2200 does not enable this feature, but
it may be enabled using the MCP2200 configuration utility (see Section 7.2 “Install”).
LEDs D12 and D13 are used by the preprogrammed demo firmware to identify the TX
and RX communication between the host and target microcontrollers.
LED D2 indicates the power availability. This LED cannot be controlled by the target
application or by the host microcontroller.
5.10
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 a
Microchip MCP1703, LDO regulator U3.

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.

The daughter board features the Semtech SX1239 Low-Power Integrated UHF
Receiver (http://www.semtech.com/wireless-rf/rf-receivers/sx1239/). The PICtail
daughter board can plug into the 28-pin PICtail connector, featured on many Microchip
Technology development tools.
The antenna connection has a pin socket for plugging a wire antenna. This
demonstrates a simple and low-cost antenna option.
The antenna pin socket can be removed by heating it with a soldering iron and cleaning
the connection. An SMA or reverse polarity SMA (RP-SMA) connector can be soldered
in place on the PCB. A whip or sleeve dipole antenna can then be used.
If an SMA+ different antenna is used, the matching circuit will be less ideal. Pre-made
antennas have a fixed, lower impedance. The wire used has a higher impedance.

6.1
INTRODUCTION
The software on the demo board was constructed so that a developer can easily
customize the existing code base. The entire code is written in ‘C’ and has clearly
documented sections where the developer can insert custom code.
6.2
PROGRAMMING THE MCS3142
Since the MCS3142 is a hardware encoder, its entire memory map cannot be
programmed. Only portions of the MCS3142 memory are programmable. Please see
Section 7.3.3 “Generate Source” for more information on how to generate code for
the MCS3142 via the MPLAB X KEELOQ plugin.
To modify the configuration data 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.
The following steps need to be followed to program the MCS3142:
• Remove the PCB board from the plastic enclosure and lay the PCB board on a
non-conductive 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.
Note:
6.3
Avoid touching the PCB antenna when testing.
DEVELOPING WITH THE EMBEDDED SECURITY BOARD
The Embedded Security Development Board acts as a receiver in the MCS3142
Wireless Security Remote Control Development Kit. The target application
microcontroller on the right side of the development board interacts with the receiver.
All data receiving and KEELOQ security functionalities are performed by the target
application microcontroller. The host microcontroller is only used to drive the LCD
display and package data for the PC interface. The developer should only need to
develop on the target side. The prototyping area under the four push buttons for target
application controller can be used to prototype the application.

Intra-Board Communication
This file contains the necessary communications between the two sides. The PC application needs to be informed of any updates relating to KEELOQ. As a consequence,
there are numerous places within the target application code that grab data and send
to the host controller. This code should be left untouched since it has no effect on the
actual data manipulation of KEELOQ.
SX1239
This is the receiver that the target uses for receiving demodulated data. It uses SPI
communication for its configuration. Please see the SX1239 data sheet for more
information regarding its numerous registers and settings.
NVM Mediator
The “nonvolatile” mediator provides access to the EEPROM where learned devices
and their settings are saved. The developer should access this using the find(),
write(), read() methods.

Chapter 7. KEELOQ MPLAB X Plugin
7.1
INTRODUCTION
The KEELOQ plugin is a utility that provides Serialized Quick Turn Programming (SQTP)
file generation for all HCS/MCS devices. Since the entire configuration is done within
the context of an existing MPLAB X project, it can be used as a general KEELOQ
programmer.
7.2
INSTALL
The plugin requires an existing MPLAB X project with an appropriate KEELOQ device
selected as its target to be set as the main project. The tool uses the current main
project inside of MPLAB X to select the correct device and workspace to attach the
generated code.
The KEELOQ plugin is available from the Plugin Center of MPLAB X.
To manually install, open up MPLAB X and browse to: Tools->Plugins->Available Plugins and then locate the KEELOQ plugin in the available plugins list.
1. An MPLAB X project must first be created or opened with the correct KEELOQ
device selected. Select File->New Project to start a new project. Follow the
rest of the steps, making sure to select a device from the KEELOQ Family.

EXPORT SQTP
7.3.1
SQTP File Generation
Serialized Quick Turn Programming serialization is a method of programming 8-bit
microcontrollers, whereby each chip is programmed with a slightly different code.
Typically, all locations are programmed with the same basic code except for a few
contiguous bytes which are programmed with a different number (referred to as ‘key’
or ‘ID number’ or ‘serial number’) in each member. Typical applications of such
programming are remote transmitters for car alarms or garage door openers where
each unit must have a different access code.
Microchip offers a flexible SQTP program for customers who wish to have their devices
programmed by the factory with unique settings. By using the MPLAB X KEELOQ plugin,
all the user has to do is specify key parameters such as manufacturer’s code and
encryption algorithm. The utility can then output a file that can be sent to Microchip for
production programming or used on a variety of Microchip and third party programmer
tools.

Viewing Data
Each of the three KEELOQ technologies contains two panels. One is a graphical view
and another is a textual-based logger with an accompanying table with two available
rows. Each row of the table represents a single learned device. The Table tab will show
relevant information to any learned device that corresponds to its KEELOQ technology.
Any data that is changed will momentarily change to a red coloring. The Panel’s tab in
which the data changed will also have its tab color change.
8.4
PAIRING A TRANSMITTER
The demo board and PC application are now synchronized with one another. Once
successfully paired, a text box will be populated with the learned data being sent to the
PC for it to keep its own records. Since each paired transmitter is kept in nonvolatile
memory, this data only needs to be saved once unless a resynchronization is required.
The application reads out every saved device upon a successful connection to the
board.
Once a device is saved in the application, a row in one of the KEELOQ table updates
itself. The following figure shows a single device that is just learned.

Classic KEELOQ
The Counter Delta box indicates the difference between two transmitters’ sync counter
values. Since the graphic updates only to the latest transmitter received, this value is
sometimes invalid until at least two transmissions from a single device are performed.
The red circle represents a simplified Synchronization window as shown in Figure 8-8.
The size of the pie is arbitrary, but the technique is fundamental.
FIGURE 8-8:
SYNCHRONIZATION WINDOW FOR THE CLASSIC KEELOQ
ALGORITHM
The synchronization counter is an always-incrementing event counter. It increments
whenever a new packet is prepared on the transmitter. Each time a transmission is
authenticated, the intended function is executed and the transmission’s synchronization counter value is stored in EEPROM. From the currently stored counter value there
is an initial “Single Operation” forward window of 16 codes. This 16-code “window” is
represented by the dotted blue line. The current sync value is represented by the black
line and the previous received by the blue line.
FIGURE 8-9:
COUNTER DELTA 1
If the difference between a received synchronization counter and the last stored
counter is within 16, the intended function will be executed on the single button press
and the new synchronization counter will be stored. Storing the new synchronization
counter value effectively rotates the entire Synchronization window.

A delta of ‘1’ is typical under normal operation. To easily see this delta grow, press the
Transmit button on the fob multiple times while being out of range from the receiver.
Then come back towards the receiver and press again. The delta will now be greater
than ‘1’.
When the sync counter gets to its maximum value, the fob needs to be reprogrammed
in order to resume normal operation again.
Advanced KEELOQ
Please see the previous section regarding how the Sync Counter window works.
KEELOQ’S Advanced Sync window has identical operation compared to Classic
KEELOQ with the exception that Advanced has a larger, 32-bit sync counter.
Ultimate KEELOQ
The pie in the Ultimate KEELOQ graphic uses the time-stamps between the transmitter
and receiver to construct a delta.
FIGURE 8-10:
ULTIMATE KEELOQ TIME-STAMP WINDOW
In the absence of a transmission, the PC will continuously increment its clock every ¼
second. A transmission will update the Receiver Clock block with the receiver’s time.
The transmitter’s time is symbolized by the black line and should land directly
in-between the two blue lines. The blue lines represent the acceptable drift between the
receiver and transmitter’s clocks. If the receiver has determined that the transmitter is
out of sync, it will force a re-sync event. The Receiver +10 secs button can be used to
simulate this re-sync event. The Delta Timer block holds the time difference between
the receiver’s clock and transmitter’s clock.
The KEELOQ block indicates the battery voltage on the recently received transmitter.
8.6
CALCULATOR
The GUI can also be used as a graphical calculator.
Some of the blocks appear raised than the others, indicating an input. The mouse
pointer will also transform into a hand as the mouse hovers over a raised block. These
special blocks are inputs to the calculator and can be used to manipulate the graphic.
Note:
All inputs to the system are in hexadecimal format.
After applying the changes, the graphic will update itself from the new stimulus. Note
that the effects are not saved to the transmitter, receiver, or inside the learned devices
table. These changes do not persist between sessions.

RECEIVER SETTINGS
The receiver settings can manipulated via the GUI. To access these options, navigate
to Settings->Board Options to see a similar screen as below:
FIGURE 8-11:
BOARD SETTINGS DIALOG
The drop-down options for the center frequency contain common settings for the
receiver. The Hex input box provides a convenient way to visual the decimal frequency
in a hexadecimal format. The modulation can also be configured between OOK and
FSK. When satisfied, press the Program Receiver button to apply the changes to the
board. The kits come with a receiver that has a matching circuit that is designed to a
specific frequency. Changing the frequency far from its originally designed center
frequency will have adverse affects on the receiving range.
Note:
8.8
These settings will not persist between power cycles of the demo board.
VERSIONING
It is advised that the latest PC application and Host/Target firmware be downloaded
from the web at www.microchip.com/keeloq. The Help window will list the firmware of
the development board and of the application.
