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. -

RESET button The EVBlpc213x board is equipped with an on-board resetting button; by pressing it we force a low state on the RESET terminal of the module. #RESET RESET Figure 11 Implementation of the RESET push-button. RS-232 interfaces EVBlpc213x has two RS232 ports with DB-9 connector. TxD and RxD lines are led to jumpers through MAX3232 transceiver. -
Page 11: Usb Interface
USB interface Board is equipped with USB interface connector. USB allows connection with PC or other USB host and transfer data with up to 1MB/s speed. Along with USB connector there are RC filtering circuits and jumper for connecting USB bus power with board +5V voltage. 100n USBDN USBDP... -
Page 12: 1-Wire Interface
Pull-up is by default turned on by R13 resistor. Active reset signal or low level on UDP_PUP line turns off pull- up, what is interpreted by USB host as disconnection of USB device. 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. -
