PIC18F2525/2620/4525/4620 7.Module:Timing Diagrams andSpecificationsTable 26-6: External Clock Timing Requirements(page 343), has been revised (changes andadditions are shown in bold text).TABLE 26-6:EXTERNAL CLOCK TIMING REQUIREMENTS8.Module:EUSARTThe RX pin sampling information in Section 18.1.2“Sampling” has changed. This section now reads as follows:18.1.2SAMPLINGThe data on the RX pin is sampled three times by a majority detect circuit to determine if a high or a low level is present at the RX pin when SYNC is clear or when BRG16 and BRGH are both not set.The data on the RX pin is sampled once when SYNC is set or when BRGH16 and BRGH are both set.9.Module:MSSPIn Section 17.3.2 “Operation”, the following note has been added:10.Module:QFNIn the QFN pin diagram on page 3 and in Table1-3: PIC18F4525/4620 Pinout I/O Descriptions, the following note has been added: Note:It is recommended to connect the bottom pad of QFN package parts to V SS.Param.No.Symbol Characteristic Min Max Units Conditions1A F OSC External CLKI Frequency(1)DC1MHz XT, RC Oscillator modeDC25MHz HS Oscillator modeDC31.25kHz LP Oscillator modeDC40MHz EC Oscillator modeOscillator Frequency(1)DC4MHz RC Oscillator mode0.14MHz XT Oscillator mode425MHz HS Oscillator mode410MHz HS + PLL Oscillator mode5200kHz LP Oscillator mode1T OSC External CLKI Period(1)1000—ns XT, RC Oscillator mode40—ns HS Oscillator mode32—µs LP Oscillator mode25—ns EC Oscillator modeOscillator Period(1)250—ns RC Oscillator mode2501µs XT Oscillator mode40250ns HS Oscillator mode100250ns HS + PLL Oscillator mode5200µs LP Oscillator modeNote1:Instruction cycle period (T CY) equals four times the input oscillator time base period for all configurations except PLL. All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at “min.” values with an external clock applied to the OSC1/CLKI pin. When an external clockinput is used, the “max.” cycle time limit is “DC” (no clock) for all devices.Note:The SSPBUF register cannot be used withread-modify-write instructions, such asBCF, BTFSC, COMF, etc.2005 Microchip Technology Inc.DS80222B-page 3PIC18F2525/2620/4525/4620DS80222B-page 4? 2005 Microchip Technology Inc.11.Module:Electrical CharacteristicsParameters D031A and D041A have been added to Section 26-3 “DC Characteristics”, as shown below:12.Module:Electrical CharacteristicsIn Table 26-1: Memory Programming Require-ments, parameters D132, D132A, D133 and D133A have been changed.

The mikroProg programmer is connected to the development system via the CN6 connector, Figure 3-9.mikroProg is a fast USB 2.0 programmer with mikroICD ™ hardware In-Circuit Debugger. Smart engineering allows mikroProg ™ to support PIC10®, PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and PIC32® devices in a single programmer. It supports over 570 microcontrollers from Microchip ®. Outstanding performance, easy operation and elegant design are it’s key features.Programing with mikroProg programmerFigure 3-9:Connecting mikroProg to mikromediaspecial programming softwarecalled mikroProg Suite for PIC. Thissoftware is used for programmingof ALL Microchip® microcontrollerfamilies, including PIC10®, PIC12®,PIC16®, PIC18®, dsPIC30/33®, PIC24®and PIC32®. Software has intuitiveinterface and SingleClick™ programmingtechnology. Just by downloading thelatest version of mikroProg Suite yourprogrammer is ready to program newdevices. mikroProg Suite is updatedregularly, at least four times a year, soyour programmer will be more and morepowerful with each new release.Figure 3-10: Main window of mikroProg Suite for PIC® programming softwarePrograming with ICD2® or ICD3® programmerThe microcontroller can be also programmedwith ICD2® or ICD3® programmer. Theseprogrammers connects with mikromediaboard via ICD2 CONNECTOR BOARD.In order to enable the ICD2® and ICD3®programmers to be connected to thedevelopment system, it is necessary to providethe appropriate connector such as the ICD2CONNECTOR BOARD. This connector should befirst soldered on the CN5 connector. Then youshould plug the ICD2® or ICD3® programmerinto it, Figure 3-11.Figure 3-11:Connecting ICD2®or ICD3® programmerBoard is equipped with reset button, which is located at the top of the front side (Figure 4-2). If you want to reset the circuit, press the reset button. It will generate low voltage level on microcontroller reset pin (input). In addition, a reset can be externally provided through pin 27 on side headers(Figure 4-3).Figure 4-2: Frontal reset buttonFigure 4-1: Location of additional reset buttonFigure 4-1.5. microSD Card SlotFigure 6-1: microSD card slotBoard contains microSD card slot for using microSD cards in yourprojects. It enables you to store large amounts of data externally, thus savingmicrocontroller memory. microSD cards use Serial Peripheral Interface (SPI) forcommunication with the microcontroller.Figure 5-1:Crystal oscillator moduleBoard is equipped with 16MHz crystal oscillator (Y1) circuitthat provides external clock waveform to the microcontrollerCLKO and CLKI pins. This base frequency is suitable for further clockmultipliers and ideal for generation of necessary USB clock, which ensuresproper operation of bootloader and your custom USB-based applications.The use of crystal in all other schematics is implied even if it is purposely left out, because of the schematics clarity.Figure 8-2: 3.5mm headphones jackThe development system features a TFT 320x240 displaycovered with a resistive touch panel. Together they form afunctional unit called a touch screen. It enables data to beentered and displayed at the same time. The TFT display iscapable of showing graphics in 262.144 diffe r ent colors. Figure 7-1: Touch ScreenOn board ADXL345 accelerometer is used to measure accelerationin three axis: x, y and z. The accelerometer function is defined by theuser in the program loaded into the microcontroller. Communicationbetween the accelerometer and the microcontroller is performed viathe I2C interface.You can set the accelerometer address to 0 or 1 by re-soldering the SMDjumper (zero-ohm resistor) to the appropriate position. Jumper is placed inaddress 1 position by default.10. USB connectionFigure 9-1: ConnectingUSB cable to Micro USBconnectorPIC18F67K40 microcontroller has an integrated USB module, which enables you toimplement USB communication functionality to your mikromedia board. Connection withtarget USB host is done over micro USB connector which is positioned next to the battery connector.Figure 11-1: Flash memory moduleSince multimedia applications are getting increasingly demanding, it is necessary to provide additional memory spaceto be used for storing more data. The flash memory module enables the microcontroller to use additional 8Mbit flash memory.
