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.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

Analog Input Filtering Circuit
The analog filtering circuit is designed for use with an electret microphone. Electret
microphones typically require biasing, which is provided by MIC bias jumper, JP3. The
analog signal generated by a typical electret microphone has a peak-to-peak voltage
in the single millivolts range. The analog filtering circuit has a maximum gain of 300,
which can be controlled with the potentiometer labeled GAIN and is a 2nd order
low-pass filter with a cut-off frequency of 5 kHz. Jumper JP3 needs to be removed if the
analog input is provided by input test point.
DS41618A-page 10
 2011 Microchip Technology Inc.
1.4.2
PWM Filtering from RC2
The microcontroller output RC2 provides an active-low pass filter that can be used to
generate analog signals. A high-frequency PWM output from RC2 can be pulse-width
modulated to vary the amplitude of the output signal.
1.4.3
PICtail™ Daughter Board Interface
The PICtail daughter board interface breaks out each pin of the microcontroller in
addition to providing +VDD and ground. The header is designed to be compatible with
existing PICtail daughter boards. Visit the Microchip web site to find more details on
PICtail daughter boards.
1.4.4
PICkit™ Serial Analyzer Connector
The PICkit serial analyzer connector provides pins for serial communication. The serial
communications lines are designed to be used with the PICkit serial analyzer, but are
also provided for general purpose communications as well. The serial communications
pinout is shown below:

ICSP™ (In-Circuit Serial Programmer™) Connector
A 6-pin ICSP programming capability and RJ-11 connectors are provided for
programming the microcontroller. The PIC18LF46K22 can be programmed and debugged
through these connectors using Microchip In-Circuit Debuggers/Programmers.
Note:
1.4.6
The programming voltage on the microcontroller VPP pin must be below 9V
according to the programming specification. Protection circuitry (8.2V
Zener with 820 Ohm series resistor) is in place to ensure that VPP does not
exceed programming specifications.
Temperature Sensor
An MCP9700 temperature sensor is located on the board. The MCP9700 is an analog
temperature sensor that provides a linear voltage output versus temperature. The
voltage output of the temperature sensor is connected to the RE1 pin of the microcontroller.
1.4.7
25LC1024 Serial EEPROM
A Microchip 1024 Kbit serial reprogrammable Flash memory with both Flash and
byte-level serial EEPROM functions is provided.
The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible
serial bus. The bus signals are a clock input plus separate data in and data out lines.
Access to the device is controlled by a Chip Select (CS) input on the microcontroller pin
RA6.

32.768 kHz Crystal
The 32.768 kHz tuning fork crystal is interfaced to the RC0/T1OSO and RC1/T1OSI
pins for use with the Timer1 peripheral.
1.4.9
128x64 OLED
The display provided on the development board is a 128x64 organic LED display. It
interfaces to the microcontroller via Serial Peripheral Interface (SPI). The controller on
the OLED is the SSD1306.
1.5
POWERING THE DEMO BOARD
The demonstration board can be powered in the following ways:
1. The board accepts a 2.5mm coaxial power connector in J3. Acceptable voltages
range from +5 to 12 VDC.
2. Microchip In-Circuit Debuggers/Programmers can be used to provide power at
connector P1 or P3. Do not exceed a voltage of 3.6 VDC or a current of 100 mA
on the board if a debugger/programmer is being used to power the board.
3. The PICkit Serial Analyzer can be used to provide power at connector P2. Do not
exceed a voltage of 3.6 VDC or a current of 100 mA on the board if the PICkit
Serial Analyzer is being used to power the board.
1.6

Chapter 2. Troubleshooting
2.1
INTRODUCTION
This chapter describes common problems when using the PIC18F4XK22 Development
Board and their solutions.
2.1.1
The board does not power up.
Make sure that the green POWER LED has turned on. If the LED is not on, check to
see that the +9V power supply is properly connected.
2.1.2
Microcontroller is not executing code.
First check to make sure that the microcontroller has been programmed with the firmware that is intended to run. If the part is programmed, ensure that the current jumpers
JP1 and JP4 are in place.
2.1.3
The microcontroller will not program.
Check to make sure that the programmer/debugger is properly connected to the PC
and powered. Make sure that the board is also powered with the +9V power supply.
Programming can only occur when the current jumper, JP1, is connected.
