Page 3: Introduction
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. -

Page 6: Board Configuration
Board configuration EVBlpc213x board has eleven configuration jumpers. Correct jumper settings are necessary for proper board operation. Placement of jumpers on the board and their description is shown below. Figure 2 Placement of configuration jumpers. Jumpers description: Default Description setting +5V supply voltage for MMlpc213x minimodule. -

Closed Closing these jumpers allows in system programming of microcontroller memory via Closed RS232 port (with use of Philips LPC Flash Utility). +5V supply voltage for external use. +3.3V supply voltage for external use. Ground. 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. -
Page 8: Push-Buttons
Push-buttons The EVBlpc213x board is equipped with four microswitches which can be connected to any lead of the microcontroller. Pushing a button causes a low state on any port terminal. +3.3V Figure 5 Implementation of push-buttons. 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. -
Page 9: Potentiometers
Potentiometers EVBlpc213x has two potentiometers, POT0 and POT1. The potentiometers can be used to simulate the outputs of analog circuits. The voltage across POTx terminals can be adjusted in the 0...3.3V range. +3.3V ADJ1 ADJ0 Figure 8 Implementation of potentiometers. Buzzer The board has a built-in acoustic signaler, controlled by a logic low state through a transistor. -
Page 10: Rs-232 Interfaces
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. -

+3.3V +3.3V 100R 1-WIRE 1WIRE Figure 12 Connection of the 1-Wire connector. JTAG connector 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. -
