KEY FEATURES
1.
External power supply 8-16 V AC/DC.
2.
Choose between external and USB
power supply.
3.
Very fast and flexible on-board USB pro
grammer. The key feature is expandabili-
ty. By downloading new software, you will
be able to program new MCUs in coming
years.
4.
DS1820 temperature sensor allows to
measure temperature with 0.5°C accu-
racy.
5.
Two RS232 ports for communication with
PC or another microcontroller.
6.
16-channels for MCU Analog-to-Digital
Converter.
7.
MMC/SD Multimedia card socket.
8.
Jumpers to select default logic state of
the appropriate pins.
9.
LCD connector allows easy connection of
LCD in 4-bit mode.
10.
Graphic LCD connector allows easy connection of GLCD.
11.
70 buttons allow control of every pin on the microcontroller.
12.
Buttons to select high/low state of the pins.
13.
See all the signals -each pin has a LED.
14.
On-board Ethernet socket.
15.
Switches on the SW2 turns on/off the LEDs on ports. Select port
to connect LEDs to. These switches are used to disconnect all
LEDs from MCU pins.
16.
Set LCD contrast according to display characteristics.
17.
Set GLCD contrast according to display characteristics.
18.
On-Board peripherals are connected to the microcontroller
via switches.
19.
Enabling/disabling ethernet connection to MCU.
20.
Reset circuit - if the reset button is pressed MCU will start execut
ing from the beginning of the program.

CONNECTING THE SYSTEM
The development system box contains a development system, product CD, USB cable,
RS232 cable and this manual.
Step no.1
First of all, take the system out of the box. Unpack the USB cable and connect it to the PC.
Do not connect it to LV18FJ yet.
Step no.2
Install the PICFlash programmer. Start the installation from the product CD:
CD_Drive:\zip\lv18picflash.zip
Step no.3
Open the folder
CD_Drive:\zip\drivers
and run installation for the appropriate operating sys-
tem. Do not connect LV18FJ until the installation is finished.
Step no.4
Connect USB cable to LV18FJ. Run and use LV18PICFlash.exe as explained in the docu-
ment ‘lv18PICFlash
with mikroICD support’
CD_Drive:\pdf\lv18picflash_manual
After these four steps your LV18FJ is installed and ready for use. You can now read a pro-
gram from the chip or load an example from the product CD.

DEVELOPMENT
INTRODUCTION
The LV18FJ development system is a full-featured development board for Microchip’s low
voltage microcontrollers. It is designed to allow students and engineers to easily test and
explore the capabilities of low-voltage microcontrollers. It also allows low-voltage micro-
controllers to be interfaced with external circuits and a broad range of peripheral devices,
making it possible for the user to concentrate on software development.
Figure 1 illustrates the development board. There are identification marks beside each com-
ponent on a silkscreen. These marks describe connections to the microcontroller, operation
modes and provide additional information. Since all relevant information is provided on the
board there is almost no need for additional schematics.
