1 Introduction
The EVBlpc213x board was created with the aim of providing a hardware base for a designer of
systems relying on the MMlpc213x minimodule, allowing to realize and verify quickly one’s own
ideas. Having this in mind, the board has been designed in such a way that the user has access
to all terminals of the module which are led out to connectors. The board houses also such
peripherals as: LEDs, push-buttons, potentiometers, a LCD display, a RS232 interfaces, and a 1-
Wire connector. All these elements are accessible through pin connectors, permitting their
connection with any processor port. The board has also a large prototype area which permits the
designer to connect other elements in any configuration. Due to the incision (v-cut) between the
prototype area and the rest of the board, the prototype part can be broken off. The board contains
also a power supply which relieves the user from the need to provide a regulated supply voltage.
Together with the board, we deliver GCC compiler as well as demonstration software.
The EVBlpc213x along with the MMlpc213x minimodule can be also used in didactic laboratories
of informatics colleges and universities. It can be also used to build circuits realizing thesis
projects.
We wish you nothing but success and a lot of satisfaction in designing and
developing new electronic equipment based on the EVBlpc213x board and
the MMlpc213x minimodule.

Board supply
The EVBlpc213x board can be supplied from an external power supply with an output of 7-12 V AC or 9-15 V
DC, having a standard plug with a bolt diameter of 2.1 mm, connected to supply socket J3. In case of a DC
supply voltage its polarity is irrelevant.
Regulated +5V and +3.3V voltages are led to J1 (+5V) and J15 (+3.3V) connectors, ground to J14.

LED diodes
The EVBlpc213x has 8 LED diodes which play the role of the simplest interface between the system and the
user. The board is constructed in such a way that it allows any connection between the diodes and
microcontroller leads. A diode lights up when a low signal level is applied to appropriate leads. The LED
current flowing into the microcontroller pin is about 3.5mA.

LCD display
MMlpc213x has place for standard 2x16 characters LCD display with HD44780 compatible controller. Display
terminals D4-D7, RS, E, contrast and backlight are led to LCD connector J7. LCD connector is designed in
this way, that it is possible to connect contrast signal to onboard potentiometer with use of jumpers, or with
use of wire to any microcontroller pin, that can generate PWM (through RC low pass filter, which can be built
on prototype area). Similarly, LCD backlight can be permanently turned on by closing jumper, or can be
controlled by any microcontroller pin.
Because LCD connector contains only higher part of display bus, it has to work 4-bit mode. Also, RW line is
permanently connected to ground, what allows only read operation, but it is sufficient to proper operation.
Such approach minimizes required microcontroller port pins to six.

potentiometer.

RS-232 interfaces
EVBlpc213x has two RS232 ports with DB-9 connector. TxD and RxD lines (and also RTS and CTS for port 1)
are led to jumpers through MAX3232 transceiver.
Stuffing jumpers causes connection of TxD and RxD signals to microcontrollers UART0 or UART1 ports.
RS232 signals can also be connected to any microcontroller’s pins with use of wires. Drawing below shows
implementation of RS232 ports.

1-Wire interface
The EVBlpc213x board has a 1-Wire bus connector. This connector can be used to connect e.g. a digital
DS1820 thermometer or Dallas/Maxim iButton reader from. The data signal has been applied to the J13
connector and designated as 1-W. It can be connected to any microcontroller lead-out by means of the

Programming/debugging of module can be done through JTAG interface.
JTAG is a four-lead interface permitting the takeover of control over the processor’s core. The possibilities
offered by this interface are, among others: step operation, full-speed operation, hardware and software
breakpoints, inspection and modification of contents of registers and data memories.
EVBlpc213x board has standard, 20-pin connector, allowing operation with all JTAG debuggers.
